# Change Log This document covers what has changed in each release of Kermit 95 since its first open-source release in 2022. For a more in-depth look at what has changed, check the git commit log. Because it's been over 20 years since the last stable release of K95, changes for the Kermit 95 v3.0 beta releases (which are already more usable than the last stable release) are temporarily included here, with the full v3.0 change log living in the [Whats New in 3.0](whats-new.md) document. When the final release of v3.0 eventually happens, the details about the various v3.0 eventually be moved elsewhere, with the full v3.0 change log taking their place. ## Kermit 95 v3.0 beta 8 - Date TBD, likely mid-2026 This release comes with *significant* changes to the way Kermit 95 handles color. While every effort has been made to ensure there are no unexpected behaviour changes to applications and terminal emulations not using more than 16 colours, these are big changes so its not impossible something may have been missed. If you notice any unexpected color changes from beta 7 in applications and terminal emulations that *do not* use the new 256-color/24-bit color modes, *please log a bug* so it can be fixed! ### Default character set for the Linux Console Terminal emulation has changed In past releases, Kermit 95 used ASCII for the remote character set when emulating the linux console terminal (the drop-down may have said latin-1 but this was a bug). As most linux distributions and other terminal emulators switched to UTF-8 by default well over a decade ago, Kermit 95 now does the same starting with 3.0 Beta 8 If this causes problems, you can restore the previous default character set by placing the following macro in your k95custom.ini file which will be executed whenever you switch to the linux terminal type: ``` def tt_linux { set term remote dec-special G3 set term remote latin1 G2 set term remote latin1 G1 set term remote ascii G0 } ``` ### A New Terminal Type: K95 This release of Kermit 95 includes a new "K95" terminal type which aims for compatibility with modern terminal software expecting something "xterm-compatible". It provides many more features and a more compatible default keymap than the previously recommended "linux" terminal type. It is, at the time of writing, *generally* compatible with xterms "xterm-256color" terminfo description, but there is always the possibility that xterm (and its terminfo description) will change in some incompatible way in the future, and Kermit 95 does a few things differently from xterm. So for the best results and fewest compatibility issues rather than just claiming to be xterm like some other terminals, Kermit 95 includes its own terminfo description. For the time being, this terminfo entry must be manually installed on any hosts you connect to. This can be easily done by just running `take terminfo.ksc` from the K95 command screen if you've got both `kermit` and `tic` on the remote host. Otherwise, you can transfer `k95.src` (included with the K95 distribution) to the remote host and run `tic -x k95.src` to install it. This will likely become the default terminal type in some future release of Kermit 95. But as the required terminfo description isn't distributed except as part of K95 at this time, the default terminal remains VT220 for now. ### New Features - Support for multiple color palettes of up to 256 colors, switchable at runtime with the new `SET TERM COLOR PALETTE` command. _Display_ of more than 16 colors is limited to the Windows GUI version of K95, with the Windows and OS/2 Console versions picking the nearest color from the 16-color palette for display - Included palettes are: - xterm 256-colors (the new default palette) - xterm 88-colors - vt525 16-colors - vt525 monochrome - vt525 alternate (uses bold, underline, blink and reverse attributes for color instead of normal ANSI color attributes) - aixterm 16-colors (the palette used by prior Kermit 95 releases) - Screen colors can be set to values from the larger palette with the `SET TERMINAL COLOR` command by using the new INDEX keyword followed by color number. For example: `SET TERM COLOR TERM INDEX 15 black` would set the foreground to color 15 in the current palette, and the background to black. - You can change colors in the larger palette with `SET GUI RGBCOLOR INDEX ` - You can show the full color palette with `SHOW GUI /PALETTE` - You can find out the currently set color palette with either the `SHOW TERMINAL` command, or the new `\v(color_palette)` variable. - You can still select the 88-color or 256-color palette in console versions of K95, but this is only for compatibility purposes. On display, the nearest color in the 16-color palette will be used instead. - Support for full 24-bit color is now available in GUI versions of Kermit 95 for Windows XP SP3 or newer. This is enabled by picking the `xterm-rgb` (256-colors + RGB) color palette, and disabled by picking any other color palette. - 24-bit color *can* be supported on older Windows releases, but is disabled for now to reduce memory requirements. If there is demand, 24-bit color versions for vintage windows can be provided in the future. - Screen colors can be set to any 24-bit RGB color with the `SET TERMINAL COLOR` command by using the new RGB keyword, for example: `SET TERM COLOR TERM RGB 255 110 00 black` would set the foreground to an amber color, and the background to black. - If 24-bit color is enabled, the telnet client will try to set the `COLORTERM=truecolor` environment variable if it can and if this behavior is not turned off with `SET TELNET SEND-COLORTERM OFF`. The COLORTERM environment variable is used by some applications rather than relying on potentially out-of-date terminfo/termcap entries to detect 24-bit color support. - The SSH client will also try to set the `COLORTERM=truecolor` environment variable if it can, but this will only work if the SSH server has been configured to accept the COLORTERM environment variable; to make it work, it will likely have to be added to the `AcceptEnv` list in `/etc/ssh/sshd_config` on the server. - Support for VT525 color including its alternate color and mono SGR color modes. - New screen elements can be given color via `SET TERMINAL COLOR` - Blinking text (if the blink attribute is disabled with the new `SET TERMINAL ATTRIBUTE BLINK OFF COLOR` command) - Bold text (if the bold attribute is disabled with the new `SET TERMINAL ATTRIBUTE BOLD OFF COLOR` command) - The text cursor - Dim text (if the dim attribute is disabled with the new `SET TERMINAL ATTRIBUTE DIM OFF COLOR` command) - New "k95" terminal type with its own terminfo description. This aims to be generally compatible with modern xterm-like terminal emulators, rather than emulating a specific hardware or unix console terminal. - Two new special keyboard modes - `META` - This is a subset of the `EMACS` keyboard mode which does not modify any function keys. - `XTERM-META` - This sets the 8th bit for keyboard input, equivalent to xterms "interpret 'meta' key" option. - Clipboard access for the remote host is now supported via OSC-52. This can be enabled or disabled for read, write or both with `SET TERMINAL CLIPBOARD-ACCESS`. You can optionally choose to be notified when the remote host attempts to access your clipboard. For security, the default is disabled with a notification. - Support for xterm focus tracking (mode 1004) - Support for DEC Private mode 8 (DECARM): keyboard autorepeat. This was the last VT10x escape sequence K95 could reasonably support. The only ones left unimplemented are the interlaced video mode, and the confidence tests neither of which can be reasonably supported by an emulator. - New experimental ADDS Regent 25 emulation - New SET BELL option to flash the window title and task bar button in addition to any visible/audible bell setting. - Synchronized Output mode - Crossed-out character attribute - VT420 text macros - REXX support has been extended to all Windows systems except for: NT 3.50 or older, and 64bit Windows systems with an Alpha or Itanium CPU. Newly supported includes: Windows 95/98/ME, Windows NT 3.51/4.0/2000 on x86/Alpha/MIPS/PowerPC, and Windows 8/10/11 on 32bit and 64bit ARM. - Xterm alternate screen (K95 terminal type only). Can be disabled with the new command `SET TERMINAL ALTERNATE-BUFFER DISABLED` - VT330/VT420 page memory - available to the K95 terminal type and (until a VT420 emulation is added) the VT320 terminal type. [DECCRA](https://davidrg.github.io/ckwin/dev/ctlseqs.html#deccra) and [DECRQCRA](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqcra) can now work across pages, while [DECRQDE](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqde) and [DECXCPR](https://davidrg.github.io/ckwin/dev/ctlseqs.html#dsr-decxcpr) now include page information - DECterm Ruled Lines - K95G can now save the terminal screen as an image rather than plain text. For example, `SAVE TERMINAL SCREEN /FORMAT:PNG screenshot.png`. The following output formats are available: - Windows Bitmap (.bmp) - Windows Enhanced Metafile (.emf) - PNG (Windows XP+ only) - GIF (Windows XP+ only) - New option to not clear the terminal screen when it is resized: `SET TERM CLEAR-ON-RESIZE { ON, OFF }` - Soft-fonts (DRCS) for VT220 and higher emulations are now supported - The VT520 Play Sound control sequence is now supported. - Proper Smooth Scroll is now supported in K95G. - New `CLEAR TERMINAL SCROLLBACK-ONLY` command. Clears the scrollback while preserving current terminal screen contents. ### Enhancements - The Control Sequences documentation ([preliminary version available online](https://davidrg.github.io/ckwin/dev/ctlseqs.html)) has been _heavily_ revised. The whole document was converted from HTML to a more bespoke format from which various HTML documents are now generated allowing for more consistent styling and easier maintenance. The new documentation now includes, where possible, references to terminal documentation for the various control sequences K95 implements (or doesn't). - The way terminal operating system commands are parsed has been rewritten to be more flexible and to make adding support for new operating system commands easier. - True bold can now be turned off in K95G with the new command `SET TERMINAL ATTRIBUTE BOLD OFF`. When off, it still affects text color unless its turned off with `SET TERMINAL ATTRIBUTE BOLD OFF COLOR` in which case the color set with `SET TERMINAL COLOR BOLD` is used. - True bold can now be turned on such that it only affects the font and not the texts color with `SET TERMINAL ATTRIBUTE BOLD ON FONT-ONLY` (this is of course incompatible with applications that use the bold attribute to access the upper eight colors) - True dim is now turned off in K95G when `SET TERMINAL ATTRIBUTE DIM OFF` is given. Like with bold, it still affects color unless turned off with `SET TERMINAL ATTRIBUTE DIM OFF COLOR` in which case the color set with `SET TERMINAL COLOR DIM` is used. - Added a new `IF REXX` test for checking if REXX support is available - Negative screen coordinates are now supported on the command line (`--xpos`, `--ypos`) and in the `SET GUI WINDOW POSITION` command. Negative coordinates may be required in multi-monitor setups to place the window on a display to the left of or above of the primary display. - New SET TERMINAL SIZE command allowing both width and height to be set in one go. - Release builds should now include the Git commit SHA they were built from in the `SHOW VERSIONS` output going forward - The linux console terminal emulation now uses the UTF-8 character set by default as most linux distributions moved to UTF-8 long ago now. - Upgrade OpenSSL to 3.5.7 - Drastic improvements in terminal throughput which helps when you accidentally cat a large file: - SSH connections are around 33x faster - Telnet and other IP connections are around 8x faster - Pipe and PTY connections are around 87x faster - Doubled maximum terminal lines to 256 in K95G on modern systems - Added a new function, `\fterminalchecksum`, which produces a checksum of the terminal screen using the same algorithm as DECRQCRA. Parameters allow you to specify a region of a particular page to calculate a checksum off. If parameters are left off it calculates the checksum of the entire page on screen. Unlike DECRQCRA, it is not bound by page margins. - `SET TERM COLOR ERASE` now takes effect immediately rather than requiring a terminal reset to take effect. - In K95G the Dim attribute is now rendered by reducing the foreground intensity by half - this matches the behavior of Xterm and the Windows Terminal. K95Gs previous approach of treating Dim as a synonym for Bold produced odd effects in PowerShell which renders autocomplete suggestions using the Dim attribute combined with whatever the foreground color is. - Updated K95Gs list of preferred fonts to include _Cascadia Mono Regular_, a Unicode font suitable for terminals which is better populated than the other fonts bundled with Windows that K95 knows about. This font was created for and also ships with the Windows Terminal and is available under an open license. The new preferred fonts list (in order) is included below. The three Andale fonts, plus Everson and Monotype are commercial fonts not likely to be present on most systems. K95G will pick the first one of these it finds if the user has never chosen a font: - Andale Mono WT J - Andale Mono 64 - Cascadia Mono Regular - Bitstream Vera Sans Mono - Everson Mono Terminal - Monotype.com - Andale Mono - Lucida Console - Courier - Terminal - System - Upgraded to zlib 1.3.2 - The Secondary DA response when the terminal type is set to VT220 or VT220PC now reports the VT220 identification code, rather than the code for VT320. - DECCARA supports changing color attributes the K95 terminal type - Added a new \v(ntime_ms) variable which provides the current time since midnight in milliseconds. - The default screen update interval is now 20 milliseconds giving a frame rate of 50 frames per second. The old default was 100 milliseconds (10fps), but overridden by the default k95custom.ini. - An updated version of ConPTY is now packaged with kermit 95 for modern x86, x86-64 and arm64 hosts to enable better terminal emulation in PTY sessions. - The PTY command will now launch the Windows shell (cmd.exe) by default if no other command is specified - WYSE WY-50 and compatible escape sequences for setting the smooth scrolling speed (`ESC `` <`, `ESC `` =`, `ESC `` >`, `ESC `` ?`) now set the appropriate smooth-scroll speed. ### New terminal control sequences > [!NOTE] > Until Kermit 95 gets a VT420 and VT525 terminal type options, control > sequences marked as requiring one of these terminals are temporarily > available under the existing VT320 terminal type instead. - [SGR-38](https://davidrg.github.io/ckwin/dev/ctlseqs.html#sgr-38-ic) and [SGR-48](https://davidrg.github.io/ckwin/dev/ctlseqs.html#sgr-48-ic) are now supported for setting colors by number using both the standard parameter-element (colon) syntax, and the old but still widely used non-standard xterm (semicolon) syntax. - [SGR-38](https://davidrg.github.io/ckwin/dev/ctlseqs.html#sgr-38-rgb) and [SGR-48](https://davidrg.github.io/ckwin/dev/ctlseqs.html#sgr-48-rgb) are now supported for setting direct 24-bit RGB colors using both the standard parameter-element (colon) syntax, and the old but still widely used non-standard xterm (semicolon) syntax. If 24-bit RGB color is not enabled or not available (eg, in the console version of K95), the nearest color in the current palette is used instead (in console versions, this is always the 16-color palette). - [DECSCUSR](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decscusr) can now control cursor blinking - [DECRQSS](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss) is now implemented for the following (VT320+ terminal type): - [SGR](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-sgr) - [DECSCA](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decsca) - [DECSCL](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decscl) - [DECSCUSR](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decscusr) - [DECSTBM](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decstbm) - [DECSLPP](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decslpp) - [DECSCPP](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decscpp) - [DECSASD](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decsasd) - [DECSSDT](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decssdt) - [DECSTGLT](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decstglt) (VT525 terminal type) - [DECSACE](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decsace) - [DECAC](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decac) (VT525 terminal type) - [DECATC](https://davidrg.github.io/ckwin/dev/ctlseqs.html#decrqss-decatc) (VT525 terminal type) - The linux console terminal emulation has been brought up to date with: - Support for [SCOSC](https://davidrg.github.io/ckwin/dev/ctlseqs.html#scosc) - Support for [SCORC](https://davidrg.github.io/ckwin/dev/ctlseqs.html#scorc) - [SGR-21](https://davidrg.github.io/ckwin/dev/ctlseqs.html#sgr-21-ul) is now underline - Three parameters for the [linux display settings](https://davidrg.github.io/ckwin/dev/ctlseqs.html#linux-disp) control sequence are now supported (linux terminal type only): - Ps = 1 - set underline color - Ps = 2 - set dim color - Ps = 3 - set current color pair as the default attribute - [OSC-R: Reset palette (linux)](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-R) (linux terminal type only) - [OSC-P: Set palette (linux)](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-P) (linux terminal type only) - SGR-38/48 - Various xterm Operating System Commands are now supported: - [OSC-2: Set Window Title](https://davidrg.github.io/ckwin/dev/ctlseqs.html#xt-wt) - [OSC-l: Set Window Title](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-l) - [OSC-4: Change Color Number](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-4) (both RGB values and X11 color names accepted) - [OSC-104: Reset Color Number](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-104) - [OSC-5: Change Special (attribute) Color Number](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-5) - [OSC-105: Reset Special (attribute) Color Number](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-105) - [OSC-6: Enable/Disable Special (attribute) Color Number](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-6) (including colorAttrMode) - [OSC-10: Change text foreground color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-10) - [OSC-110: Reset text foreground color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-110) - [OSC-11: Change text background color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-11) - [OSC-111: Reset text background color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-111) - [OSC-12: Change text cursor color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-12) - [OSC-112: Reset text cursor color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-112) - [OSC-17: Change text selection background color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-17) - [OSC-117: Reset text selection background color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-117) - [OSC-19: Change text selection foreground color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-19) - [OSC-119: Reset text selection foreground color](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-119) - [OSC-52: Manipulate selection data](https://davidrg.github.io/ckwin/dev/ctlseqs.html#osc-52).

Fixed an issue introduced in beta 7 which could cause SSH connections made via the dialer to cause K95 to crash - Fixed a typo on the `help screen` output (was SCRSTR, should be SCRNSTR) - Fixed a potential memory leak in the status line display. Cov-462304. - Fix control flow issue which could cause a DECRQM to do both the DECRQM and a Delete lines. Cov-462454. - Fix potential memory leak if SSH key generation fails. Cov-462508, Cov-462436 - Fix potential memory leak on ssh connect if existing connection fails to close. Cov-462163. - Fix Ctrl+C during an autodownload causing a crash - Fixed VT emulations not rendering SUB. When the VT100 and up receive a SUB character they render it as a shaded block for the VT1xx, and a backwards question-mark for the VT220 and up, as well as canceling any escape sequence. K95 will now do the same, using unicode character 0x2426 for VT220 and up. Not all fonts include this symbol, but on modern Windows Cascadia Mono does. (K95 bug 815). - Fixed a bug in the previous release that caused the backspace key to not work correctly for some "SET SSH" commands - Fixed `CLEAR APC` preventing execution of further commands in the APC sequence, access to the kermit prompt or the ability to switch back to the terminal. This bug first appeared in Kermit 95 v1.1.21. (K95 bug 837). - Fixed `CLEAR APC` defeating all safeguards around APC commands allowing a malicious host to switch APC processing to UNCHECKED. This bug first appeared in or prior to Kermit 95 v1.1.15. (K95 bug 838). - Fixed an error in the `help clear` output: the command is CLEAR APC, not CLEAR APC-STATUS. This error first appeared in K95 1.1.19. - Fixed connect command not reconnecting disconnected SSH sessions - Fixed certain menu items not being disabled when they should be if they appear in the system menu rather than menubar - Fixed a bug where the random number generator would not be initialized on the thread that runs the command screen resulting in `\frandom()` producing the same sequence every time. This only affected builds without SSL support (those targeting Windows versions older than XP), as when OpenSSL is available its random number generator is used instead. - Fixed two bugs in the REDIRECT command, both of which were previously fixed in the PIPE command: - Fixed Kermit 95 not detecting when the subprocess ends - Fixed I/O not being redirected in K95G - Fixed a whole host of problems with the host-writable status line: - The K95G window no longer tries to resize to the dimensions of the status line (80x1) when the cursor is moved there via DECSASD - K95G should no longer crash if the host tries to write to the status line shortly after moving the cursor there - You can now resize the terminal while the cursor is in the status line, and doing so no longer breaks the host-writable status line. - Text-mode popups now work when the cursor is in the status line - The cursor no longer vanishes while the host is in the status line in K95G - Fixed mark mode when the cursor is in the status line - Fixed setting and going to bookmarks while the cursor is in the status line - Fixed viewing the scrollback while the cursor is in the status line - Fixed searching the scrollback when the cursor is in the status line - Indicator status line is now shown during scrollback for host-writable status line - The status line is now temporarily shown by enlarging the K95G window when searching or using bookmarks if it is currently off. - Fixed turning the status line on after making a connection (or resetting the terminal) giving a black empty status line rather than the indicator status line you were likely after. This issue was particularly noticeable with the linux terminal type which has the status line off by default. - Fixed an issue in the dialer which could cause it to crash if the path was too long - The x86-64 version of Kermit 95 now works on Windows XP x64 Edition - Fixed DECCRA not copying attributes or obeying DECOM - Fixed DECXCPR response - it was leaving the '?' character out - Fixed DECSCPP parameter not being optional, and setting the terminal to maximum width if the parameters value is 0. Any value less than 80 will now produce an 80 column terminal, and any value greater than 80 will produce a 132 column terminal except for the K95 terminal type which behaves as DECterm and VTstar do allowing any width. Also fixed it clearing the screen when it shouldn't, and not erasing the area past the new last column when it should. - Fixed crash writing to unopened file - Mostly fixed incorrect DECRQCRA calculation. The result will now match what is produced by a real VT420/520 using the ISO Latin 1 character set, and should be correct for the VT525 too. The calculation doesn't currently handle other character sets, so for those the result will be incorrect. - Fixed K95G attempting to save a null font face name to the registry when the registry key isn't present and the user has never selected a font. This could result in garbage being saved as the font face name in the registry resulting in an odd font selection next time K95G is run. - Fixed crash opening serial ports on Windows NT 3.1 - VT-compatible emulations: - Fixed CUU not obeying the top margin while mode DECOM is reset - Fixed CUD not obeying the bottom margin while mode DECOM is reset - Fixed DECBI and DECFI only scrolling the line the cursor is on instead of the entire area within the margins as it should. And also fixed DECBI and DECFI scrolling the screen when the cursor is outside the margins. - Fixed CHT being ignored if a zero was passed as the parameter - Fixed NEL and CNL not obeying DECOM - Fixed VPA not obeying DECOM - Fixed CNL causing a scroll at the bottom margin - Fixed HVP/CUP not obeying DECOM properly - Fixed DECIC and DECIC, which was: - only ever inserting/deleting a single column regardless of parameter - operating outside margins - not operating at the left of the screen (DECIC) - Fixed IL and DL operating outside the page margins, and not sending the cursor to the left margin. - Fixed DECSERA, DECSEL and DECSED erasing visual and line attributes when they shouldn't. - Fixed ICH inserting characters with the current attribute, rather than current erase colour - Fixed DECFRA not filling with current SGR or protection attributes, and not obeying DECOM - Fixed DECSERA, DECCARA and DECRARA not obeying DECOM - Fixed DECERA not obeying DECOM, and not erasing cells with null - Fixed potential crash when exiting the console version of K95 - Fixed possible read past end of string in `TAKE` command - Fixed possible read past end of string in `DIR` command - Fixed possible read past end of string in array name parser (function arraynam) - Fixed the japanese-roman (JIS Roman) character set which has been broken since K95 1.1.21. This character set was specifically excluded from being considered a national replacement character set since at least 1996 though that didn't seem to cause problems until 2002. Unfortunately without source history for K95 I've no way of knowing what change broke it, so I've removed the code that was preventing it from being considered a national replacement character set which seems to have fixed it. (K95 bug 842) - Fixed the Clear Scrollback option causing a crash if the terminal is busy receiving a lot of data. Previously K95 would delete and recreate the buffer, now instead it will just reuse the existing one erasing lines as they are reused. - Fixed position 5/15 (0x5F) in the DEC Special Graphics Character set being underscore when it should have been the empty character / null. ## Kermit 95 v3.0 beta 7 - 27 January 2025 As of Beta 7, C-Kermit for Windows has been renamed back to Kermit 95, the name it carried from 1995 through to 2013. ### Things to be aware of when upgrading * K95G no longer opens COM1 by default. If you previously depended on this, you'll need to add `set port com1` to your k95custom.ini * The mouse wheel now scrolls half a screen at time, rather than one line at a time. If you'd prefer to retain the old default, put the following in your k95custom.ini: ``` set mouse wheel up none \Kupone set mouse wheel down none \Kdnone ``` #### The default SSH directory has changed! The default SSH directory in beta 7 has changed from `\v(home).ssh` back to `\v(appdata)ssh`, the location used by Kermit 95 2.1.3 and earlier. This means Kermit 95 may not find your known hosts file, or your identity (public key authentication) files after upgrading to beta 7. If you'd prefer to keep these files in `\v(home).ssh`, the same location used by OpenSSH on modern versions of windows, add the command `set ssh directory \v(home).ssh` to your k95custom.ini > [!TIP] > To find out where `\v(appdata)`, `\v(home)` and other such directories are > on your disk, you can use the `orient` command. ### New features * SSH Port forwarding (tunneling) is now supported again in both the Direct/Local and Reverse/Remote forms. You can add forwards before establishing a connection with `SSH ADD { local, remote }` and remove all forwards of a given type with `SSH CLEAR { local, remote }`. As in past releases of Kermit 95, these commands don't have any effect on an already established SSH connection - this may be changed in the future. * New command to allow removing individual port forwards (`SSH REMOVE { local, remote }`) - previously Kermit 95 only had commands to remove *all* forwarded ports of a given type. * X11 forwarding is back. Turn on with `SET SSH X11 ON`, and set your display with `SET TELNET ENV DISPLAY` * The SSH backend has been moved into a DLL. On startup, K95 attempts to load the backend DLL provided the `-#2` command line argument has not been supplied. If no SSH backend gets loaded, you can load one manually with the new `ssh load` command. This allows K95 to load the appropriate backend automatically based on operating system (Windows XP or not) and presence of MIT Kerberos for Windows. This removes the need to manually shuffle around ssh.dll variants, and also means that alternative SSH backends not based on libssh can now be supported should anyone want to build one, opening the door to SSH on vintage windows or OS/2 systems. * SSH is now supported on 32bit ARM devices (Windows RT) for the first time * Initial very limited SSH agent support has been added. Libssh is currently the limiting factor here and SSH agent support in K95 likely won't get much better without significant improvements to libssh in this area. See the SSH Readme for more details. * REXX support has been extended to x86 systems running Windows XP or newer. This was previously an OS/2-only feature. You can now run REXX scripts and commands from the K95 command mode with the `rexx` command, and REXX scripts run from K95 can execute any Kermit 95 command by enclosing the K95 command in single quotes (eg, `'set parity none'`). For full details, see the REXX section of the K95 manual: https://kermitproject.org/k95manual/os2k95.html#os2rexx. The REXX implementation is the current Regina REXX release. regutil.dll is included but note that the Console I/O Routines it provides are not currently compatible with K95. The rexxre.dll external function package is also included providing support for POSIX regular expressions. * New command to turn the menubar on or off: `set gui menubar visible { on, off }` When the menubar is turned off in this way (rather than with the command line parameter), important menu items are moved on to the system/control/window menu (right-click on the title bar for the actions menu and a few other things): ![k95-sysmenu](https://github.com/user-attachments/assets/4a016ca5-f339-43c5-83e8-7b899b28d117) * New command to turn the toolbar on or off: `set gui toolbar visible { on, off }` * New command to turn the statusbar on or off: `set gui statusbar { on, off }` * New screen scroll kverbs: * `\Kuphscn` - Scroll up half a screen * `\Kdnhscn` - Scroll down half a screen * IBM OS/2 support is back! It should work on IBM OS/2 2.0 or newer with optional TCP/IP support provided by IBM TCP/IP 2.0 or newer. No SSH or Presentation Manager GUI as in past Kermit/2 releases. Additionally: * No PC/TCP 1.2 or IBM TCP/IP 1.2.1 support (no SDK license; the DLLs from K95 2.1.2 should work if you need it) * No dialer yet (crashes when built with Open Watcom) * No SSL/TLS support (can't be built with Open Watcom) * No legacy telnet encryption (no longer useful, but may return in a future release anyway) * Reimplemented the three checkboxes in the Dialers GUI settings page for the menu bar, toolbar and status bar. These options were new in Kermit 95 2.1.3 but were not present in previous open source releases of the dialer as it's based on code from K95 2.1.2. Any dialer entries edited with the dialer from C-Kermit for Windows betas 4-6, or Kermit 95 2.1.2 or older, will have these checkboxes default to ON. Entries last edited with the K95 2.1.3 dialer will have these three settings preserved. Turning off the GUI bars in this way does so via command line arguments rather than the new `set gui` commands so they can't be turned back on with the new `set gui` commands. * Added support xterms Bracketed Paste feature * Most of the users guide has been revised for this release and is now included as part of the release. The _Kermit Security Reference_ and sections dealing with installing and uninstalling kermit 95 are still waiting to be overhauled. ### Minor Enhancements and other changes * All executables (*.exe, *.dll) now have proper versioninfo resources * Upgraded to OpenSSL 3.4 which fixes a number of bugs and security issues and will receive security fixes until October 2026. * K95G no longer opens COM1 by default. If you still want this behaviour, add `set port com1` to your k95custom.ini * The command `set gui toolbar off` has been renamed to `set gui toolbar disabled` to better describe what it actually does and to make room for new commands to turn it on and off. The previous syntax (`set gui toolbar { off, on }`) is still accepted for compatibility with existing scripts. `set gui toolbar on` still does nothing as it always has (disabling the toolbar is a session lockdown feature) * The command `set gui menubar off` has been renamed to `set gui menubar disabled` to better describe what it actually does and to make room for new commands to turn it on and off. The previous syntax (`set gui menubar { off, on }`) is still accepted for compatibility with existing scripts. `set gui menubar on` still does nothing as it always has (disabling the menubar is a session lockdown feature) * Implemented the `set ssh identity-file` command * Added new command `set ssh directory` which allows you to set the default location where K95 looks for user known hosts and identity files. * The default SSH directory has changed from `\v(home).ssh` back to `\v(appdata)ssh` * The `ssh key` commands will now default to opening or saving keys in the SSH directory. * The `skermit` command now has help text * The default mouse wheel configuration has changed: * Wheel up/down now scrolls up/down half a screen (like PuTTY) rather than a single line. This provides better much speed than a line at a time with better usability than a screen at a time. * Shift+Wheel up/down now scrolls up/down one line * Improve exit time when the console version (k95.exe) is just being run to show usage information (`k95.exe -h` or `k95.exe --help`). Previously K95 would pause for about 5 seconds after printing usage information before returning you to the shell. * Fixed the `telnet.exe` and `rlogin.exe` stubs - these now behave as in K95 2.1.3 * Added the `ssh.exe`, `ftp.exe` and `http.exe` stubs that were included in K95 2.1.3 * `iksdnt.exe` is now included. ### Fixed bugs * Fix `fopen` causing a crash. This issue seems to have come in some recent version of the Microsoft C Runtime. * Fix hitting backspace in an empty search-in-buffer crashing * Fix `pty dir` (or trying to run anything else that isn't a valid program) causing a crash * Fixed POTS modem support not being available on NT 3.50 * Fixed OpenSSL libraries not being included in the ARM32 distribution * Fixed \Kexit (Alt+x by default) not updating the state of the associated toolbar button * Fix the SSH global known hosts file not being set to something sensible on windows. It's now set to the value used by past Kermit 95 releases by default: `\v(common)ssh\known_hosts2` * Fixed generation of 4096 RSA SSH keys * Fixed stdout parameter not working correctly * Fixed a pair of issues in the OS/2 NetBIOS implementation which has likely been totally broken since Kermit 95 v1.1.17: * `SET HOST` doing nothing for NetBIOS connections * NetBIOS name not being correctly padded when making a connection to a NetBIOS Server * Fixed emacs turning off mouse reporting when started * Fixed K95G hanging when closing the window or using File->Exit with when a connection is active and GUI dialogs are turned off * Fixed K95 bug 797: Dialer generated connection scripts will no longer include `SET LOGIN PROMPT` or `SET LOGIN PASSWORD` commands if those fields do not have a value as this broke the use of the standard login.ksc script. * Fixed K95 bug 770: When editing an FTP entry in the dialer the general settings page doesn't load the port number causing it to be cleared on save. * Fixed `TYPE` command error "The /HEIGHT switch is not supported without /GUI" when the `/HEIGHT` switch has not been supplied. ### Other Source Changes * Fixed a selection of build warnings, and improved compatibility with the Open Watcom compiler. ## C-Kermit for Windows 10.0b11 beta 6 - 11 August 2024 This is a minor release focused on upgrading from OpenSSL 1.1.1 (which is now out of support) to OpenSSL 3.0.x, and libssh 0.10.5 to 0.10.6. Also included are a selection of bug fixes and other minor enhancements. Also in this release: official support for Windows NT on Alpha and PowerPC has returned after being discontinued in March 2000 and April 1998 respectively. And for the first time ever, C-Kermit is now supported on Windows NT for MIPS computers, though without TAPI support. This is also the last release carrying the "C-Kermit for Windows" name. The next release will be Kermit 95 3.0 beta 7. ### Things to be aware of when upgrading Windows XP users: current versions of libssh are no longer compatible with Windows XP. See the included SSH Readme for a workaround for SSH support on Windows XP. ### Fixed Bugs * Fixed directory listings not reporting a size or modified time for files requiring more than 32 bits to store the file size on Windows NT 3.51 and newer. This issue will remain on NT 3.1/3.50. * C-Kermit will now find the dialer correctly if C-kermit isn't started from the dialer. This behaviour was broken by rebranding the Kermit 95 dialer - C-Kermit looks for it by its window title. * The default k95custom.ini no longer produces an error when it's run in the console version of C-Kermit or in a build of C-Kermit that lacks SSH support. * Fixed the SSH, SSL and Kerberos options in the dialer not being available or not working correctly when they should be. These options are now permanently enabled whether the bundled version of C-Kermit supports these features. Previously the dialer tried to load the Kerberos, OpenSSL and SSH DLLs to see if they were there. This no longer works due to changing DLL names (due in part to changing library versions) and the fact these DLLs are now often built for 64bit while the dialer remains 32bit. * The SSH client will now check which authentication methods are allowed by the server after each authentication method is attempted. This allows the client to handle servers which change their list of allowed authentication methods during login. * Fixed `show network` command showing "SSH V1 and V2 protocols - not available" in builds that *do* have SSH support * Fixed `show network` command showing "SSH V1 and V2 protocols" when SSH V1 is no longer supported in C-Kermit for Windows. * Fixed not being able to resize the terminal area to greater than the primary display in K95G. For example, if the window was moved on to a display that was taller than the primary display and maximised the bottom of the terminal screen would not be correctly rendered. This fix only applies to modern versions of Windows. * Fixed included openssl.exe not working on Windows XP * Fixed paging for the "help options all" command where argument help contains line breaks ### Minor Enhancements and other changes * Upgraded to OpenSSL 3.0.14, the current long term support release (supported until 7 September 2026) * Updated to libssh 0.10.6 * Updated to zlib 1.3.1 * Help text for "set gui window position" updated: this command *is* supported and it does work. * The default k95custom.ini now displays a message the console-mode version (k95.exe) is run pointing new users to the GUI version (k95g.exe) * The SSH client will now attempt authentication methods in the order specified by `set ssh v2 authentication` (the list is now ordered rather than being simply a list of what is allowed). The default order is: none, gssapi, public key, keyboard-interactive, password. * Binaries are now provided for Windows NT running on Alpha, MIPS and PowerPC systems. * Upgraded to C-Kermit 10.0 Beta.11 * About window (Help -> About) now includes the beta number * Added help text for `set terminal autopage` and `set terminal autoscroll` * Increased the maximum number of terminal columns from 256 to 512 in K95G. This should be enough to fill a 4K display at with a 10pt font or larger. As this change increases memory requirements by around 1MB whether the extra columns are used or not, it has only been increased in builds targeting modern PCs. Vintage PCs will still be limited to 256 columns. * CKW no longer rejects updated OpenSSL DLLs provided the major and minor versions match. ### New features * Implemented the DECRQCRA VT420 escape sequence which is required by esctest2. This is disabled by default due to its security risks, but can be enabled with `set terminal send-data on`. As C-Kermit doesn't currently have a VT420 terminal option yet, select VT320 to make use of VT420 features. ### Source Changes * Some minor changes to support a future replacement for the dialer. * Fixed over 1,000 build warnings. Some of the things warned about could lead to application crashes on 64bit windows. ## C-Kermit for Windows 10.0b10 beta 5 - 3 July 2023 This release mostly focused on porting the codebase to 64bit Windows - x86-64, ARM64, Itanium and even the never publicly released 64bit Windows 2000 for Alpha. Also included are a selection of minor enhancements, features and bugfixes. ### Things to be aware of when upgrading This release corrects some issues with the DEFAULT template which the Dialer creates automatically on first run. The auto-created template has bad colour values for colours 1 through 9 resulting in blue appearing green, etc (terminal sessions that should have a blue background will have a green one). The correct values are in the table below - these should be applied to the DEFAULT template as well as any other connections or templates you've created via the *GUI Settings* page:
Colour RedGreenBlue
1 - blue 0 0 127
2 - green 0 127 0
3 - cyan 0 127 127
4 - red 1270 0
5 - magenta 1270 127
6 - brown 127127 0
7 - lightgray192192 192
8 - darkgray 127127 127
9 - lightblue0 0 255
The default logfile names in the *Log File Settings* page should also start with the `\` character - by default in prior versions they started with an invalid non-printable character. In Kermit 95 the defaults did not start with \v(appdata) so you may wish to just remove this prefix entirely instead of correcting the first character. If you have Kermit 95 installed these bugs likely doesn't affect you - while the Kermit 95 dialer has them too, Kermit 95 shipped with `C:\ProgramData\Kermit 95\dialinf.dat` which contains a DEFAULT template containing the correct values. ### New Features * Builds for 64bit Windows * x86-64 * ARM64 * Itanium * Build for ARM32 * Added TLS SNI support for the http and telnet clients * The old hostmode and other scripts are now included in the distribution with no substantial changes since Kermit 95. * Kerberos V support has returned (Kerberos IV support can be built from source) * GSSAPI authentication in the SSH client (requires MIT Kerberos for Windows, see ssh-readme for more information) * Updated to C-Kermit 10 Beta.10 * Updated to libssh 0.10.5 * Updated to OpenSSL 1.1.1u ### Fixed Bugs * Fixed crash on startup under Crossover on MacOS and Wine on Linux * Fixed `show terminal` command showing autodownload as being "on" when it was actually set to "ask" * Fixed receiving files with an as-name that includes a path using UNIX separators failing when autodownload is set to "ask" in the GUI version of CKW (receiving a file sent as `send foo.txt C:/temp/foo.txt` now works) * Fixed CKW for modern Windows (XP SP3+) not setting modified time on received files * Fixed entering plane-1 unicode values via Alt+n crashing the application (this bug was inherited from Kermit 95) * Fixed SSH bugs: * anonymous SSH (userauth none) doesn't work * buffer not flushed on logout * fixed some (but not all) occurrences of a server disconnect not being detected * `set syslog` works again - this was accidentally removed in beta 4. * The colours in the dialer *GUI Settings* for the DEFAULT template automatically created when first run were completely wrong. This bug affected Kermit 95 as well but most users wouldn't have seen it as the shipped dialinf.dat included a DEFAULT with the correct settings (along with a selection of other templates). * The default log file names in the *Log File Settings* page for the DEFAULT template automatically created when first run begin with an invalid non-printable chracter instad of '\'. This bug affected Kermit 95 as well. ### Minor Enhancements and other changes * The sample k95custom.ini file now sets: * autodownload to "on" rather than "ask" * resize mode to change terminal dimensions * SSH heartbeat on * New escape sequences in the terminal emulator * `CSI 1 8 ; Ps ; Ps t` - get text area size in characters (xterm) * `CSI > Pm t` - this is now parsed and ignored, previously this xterm-specific escape sequence would incorrectly minimise the window * A sample IKSD initialisation script is now included in the distribution Setup instructions are here: https://kermitproject.org/k95manual/wiksdadm.html * The "show features" command now includes the availability (or lack of) DECnet, SuperLAT and PTY support. Some of these are optional features for custom builds only and others may or may not be present depending on the compiler used. * "show versions" now shows OS version more correctly * Updated the dates and version numbers for windows-specific entries in the "show versions" command * k95custom.ini is now distributed as k95custom.sample to prevent customised user files from being accidentally overwritten when upgrading. The default k95.ini will now rename k95custom.sample to k95custom.ini if it can't find an existing k95custom.ini in any of the usual locations. * Updated the About dialog: xyzmodem and pathworks support are no longer guaranteed to be missing. * Improvements to the terminal status line: * Increasing the window width now gives more space to the hostname and protocol fields * If the hostname and protocol text are too long to fit, the exit text ("Command: Alt-X" by default) is hidden to make room * Maximum length for exit text increased from 20 to 30 characters (where there is room to display it) * When there is sufficient room available an extra two columns of padding is inserted between the exit text and the hostname to match the other fields ### Source Changes * Fixed build failure with Visual C++ 2017 * Fixed build failure with Visual C++ 4.1 and 4.2 * Fixed some reported build errors with Visual C++ 4.0 RISC Edition. MIPS should now build fine with TAPI disabled, PowerPC may also need debug logging turned off (`set CKF_DEBUG=no`). No one has tried building the dialer yet. * Fixed build issues with the DEC Alpha compiler in the NT 3.50 SDK. The linker supplied in the SDK is not compatible, however. * Ported to 64bit Windows * Added support for building for 64bit Windows on the DEC Alpha (AXP64 target) * Ported the core of the application to MinGW (GCC) * Added support for Visual C++ 1.0/1.1 32-bit edition * Ported to Windows NT 3.10 but there are currently unresolved bugs (networking is broken for one) * SRP support is now available as a custom build option. You'll need quite an old and insecure version of OpenSSL (1.0.1u works) and an old compiler too (Visual C++ 2003 works) * DES/CAST crypto can now be statically linked into k95.exe/k95g.exe/iksdnt.exe instead of being delivered as a shared dll (k95crypto.dll) * Building with jom (or any other sufficiently compatible nmake clone) instead of nmake is now supported for Visual C++ builds. Just `set make=jom.exe` to make better use of multicore systems. ## C-Kermit for Windows 10.0b8 beta 4 - 15 December 2022 This release is mostly a collection of minor improvements and bug fixes as I have been unexpectedly busy since the prior release resulting in the schedule slipping somewhat. ### Things to be aware of when upgrading * The third mouse button is now supported in k95g which may affect any scripts you have that map mouse buttons. On a three button mouse: * Previously: Left was button 1, Middle was unsupported, Right was button 2 * Now: Left is button 1, Middle is button 2, Right is button 3 * Updates to the Dialer to support new SSH settings have resulted in the version number for the dialer data file being bumped. It is advised you take a backup of your existing data file before running the new version of the dialer for the first time. * On first start, your data file(s) will be upgraded to the new format * SSH connection scripts generated by the new dialer will not be compatible with Kermit 95 due to a difference in supported SSH options. ### New Features: * Upgraded from C-Kermit 10.0 beta.04 to beta.07, plus beta.08 changes from the 11th and 12th of December 2022. * [New in C-Kermit 10.0 Beta.05](https://kermitproject.org/ckupdates.html#ck100beta05) * [New in C-Kermit 10.0 Beta.06](https://kermitproject.org/ckupdates.html#ck100beta06) * [New in C-Kermit 10.0 Beta.07](https://kermitproject.org/ckupdates.html#ck10beta07) * [New in C-Kermit 10.0 Beta.08](https://kermitproject.org/ckupdates.html#ck10beta08) (Only up to and including 12 December 2022) * The default `k95custom.ini` now outputs a message on startup directing new users to have a look at and optionally customise the file * X/Y/Z MODEM support is back thanks to Jyrki Salmi of Online Solutions Oy (www.online.fi) providing his "P" X/Y/Z MODEM library under the same license as C-Kermit for Windows * Terminal mouse reporting * X10 protocol (send button + coordinates on mouse down) supported for Linux and ANSI terminal types * X11/Normal, URXVT and SGR protocols (send button + modifiers + coordinates on mouse down and mouse up) supported for all terminal types * Mouse wheel supported for all but the X10 protocol: You can scroll the panels in midnight commander with the mouse wheel! * New command: `set mouse reporting x` where x is one of: * `disabled` - mouse events will not be reported * `enabled` - Applications can turn mouse reporting on. Mouse reports will be sent only if a mouse event is mapped to `\Kignore` (eg, if you map right-click to `\Kpaste` then right-click will never be sent) * `override` - Applications can turn mouse reporting on. All mouse events will be sent to the remote host and any configured action in CKW will be ignored when mouse reporting is on. For example, if you map right-click to `\Kpaste` this will only have an effect outside of applications that turn mouse reporting on. * The `show mouse` command shows the mouse reporting setting plus current state (if it's active or not, and the protocol in use) * The old registry tool (`k95regtl.exe`) is back and fixed up for C-Kermit as an interim solution until a proper installer is created. This tool lets you create desktop & start menu shortcuts and the .ksc file association. * The dialer is now included by default with C-Kermit for Windows as changes to the SSH options render it incompatible with Kermit 95 (and the Kermit 95 version incompatible with CKW) * DECnet support has been re-enabled. You must install a licensed copy of Pathworks32 in order to make LAT or CTERM connections. * SuperLAT support is now available as a custom build option - it is not enabled by default due to the unclear license on the publicly available Meridian SuperLAT SDK. * The Telnet Encryption Option (DES/CAST) is supported again, not that you should use it if you care about security. ### Fixed Bugs * Fixed a bug introduced in beta 3 that can prevent the cursor and other elements on the screen with the blink attribute set from blinking reliably * File transfers over SSH are now _much_ faster * Fixed the `set mouse activate` command (aka `set terminal mouse`) in K95G - previously this command only worked in the old console version. * Fixed support for the third mouse button in K95G - previously this only worked in the old console version. This change may affect your mouse button mapping! * Fixed a mark being set (and not cleared on mouse button release) on drag when the drag event is mapped to `\Kignore` * Fixed decoding of mouse scroll wheel event coordinates * The context (right-click) menu in the dialer now works again * The manual command now works * The `show mouse` command no longer tries to output non-printable characters bound to mouse events * SSH will now prompt for a username if the default login userid has been cleared (this is how Kermit 95 behaved) * Fixed SSH help error: hmac-md5 is not supported, but hmac-sha1 is * The GUI window now resizes correctly on Windows NT 3.5x ### Minor Enhancements and other changes: * Upgraded to zlib 1.2.13 fixing [CVE-2022-37434](https://nvd.nist.gov/vuln/detail/CVE-2022-37434) * Upgraded to openssl 1.1.1u * The libssh version number is now included in the output of the `show ssh` command * The default k95custom.ini now sets the default browser to nothing which should result in Edge being used instead of Internet Explorer. This is just a temporary workaround for the default browser not being correctly picked up. * Dialer: removed SSH v1 options as CKW now supports SSH 2.0 exclusively * Dialer: Updated the lists of available ciphers, macs and host key algorithms to match what CKW actually supports ### Source Changes: * The Dialer now builds with Open Watcom 1.9 and Visual C++ 2.0 * dropped the /ALIGN linker flag which has produced a linker warning since Visual C++ 5.0 SP3 (November 1997) ## C-Kermit for Windows 10.0b4 beta 3 - 14 September 2022 This release focused on improving SSH support, returning SSL support, minor enhancements, porting to new platforms (NT 3.50, OS/2) and new compilers (Visual C++ 2.0, Open Watcom 2.0, Open Watcom 1.9 for OS/2) ### New Features: * Idle SSH sessions can now be prevented from timing out by supplying some interval to the "set ssh heartbeat" command, for example: set ssh heartbeat 60 * Added support for "user@host" syntax to SSH command. "ssh root@myhost" should do the same as "ssh myhost /user:root" now. The implementation is pretty basic and may not handle weird input well but when it works it should be less confusing to new users. * Added mouse wheel support. By default, it scrolls one line at a time, or one screen at a time when holding Ctrl. You can remap this to whatever you like via the new "set mouse wheel" command which works like "set mouse button". * File save dialogs are now the modern (normal) type on Windows ME, 2000 and newer. Windows 95, 98 and NT4 retain the old Windows 95-look file dialogs as before. * The Shell Execute utility, se.exe, is back. Documentation is here: https://kermitproject.org/k95manual/url.html#urlsexe * SSL and TLS support has returned. The http command can now make https connections, secure telnet (telnet-ssl) works again, as does ftps * SSH is now supported on Windows XP (for now - it will probably disappear in a year or so when OpenSSL drops XP support) * The screen update interval is no longer fixed at 100ms - you can now change it with the "set terminal screen-update fast" command. Smaller intervals will feel smoother. If the interval is too small for your computer elements that are supposed to blink (such as the cursor if noblink is not set) may not blink or may not blink consistently. * The /subsystem qualifier now works on the SSH command, as does the "skermit" command allowing you to use kermit as an SSH subsytem. Documentation: https://kermitproject.org/skermit.html * SSH Keyboard Interactive authentication is now supported * New SSH-related command: set ssh v2 key-exchange-methods * "set tcp nodelay" should affect SSH sessions now too * Implemented these SSH-related commands: * set ssh v2 ciphers * set ssh v2 hostkey-algorithms. New options: ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521, rsa-sha2-256, rsa-sha2-512, ssh-ed25519 * set ssh v2 macs. New options: hmac-sha1-etm@openssh.com, hmac-sha2-256, hmac-sha2-256-etm@openssh.com, hmac-sha2-512, hmac-sha2-512-etm@openssh.com, none * set ssh heartbeat-interval * ssh key create * ssh key display * ssh key change-passphrase ### Fixed Bugs: * Fixed bug where some applications (eg, nano, htop) wouldn't come back properly after being suspended with Ctrl+Z and restored with `fg` when using the linux terminal type. * Fixed terminal being cleared the first time you move the K95G window and possibly the other random occurrences of this happening * Fixed terminal scrolling bug in Open Watcom! Builds done with Open Watcom are now functionally equivalent to Visual C++ 6 in platform support and features and have no known issues unique to that compiler. * Fixed auto-download "ask" setting not working on Windows NT 3.51 * Receiving large files (>4GB) no longer fails with "Refused, size" * Fixed the "space" command never reporting more than 4GB of available free space * Fixed incorrect (too narrow) window size on first run ### Minor Enhancements and other changes: * Improved error message when no authentication methods supported by the SSH server are enabled * Upgraded to libssh 0.10.3 * Adjusted how the cursor is drawn so it blinks more nicely in the GUI version of CKW * Removed these SSH commands as they are obsolete and will never be supported by libssh, the SSH backend used by CKW: * set ssh v1 * set ssh version 1 * set ssh v2 authentication {external-keyex, hostbased, srp-gex-sha1} * set ssh v2 ciphers {arcfour, blowfish-cbc, cast128-cbc, rijndael128-cbc, rijndael192-cbc, rijndael256-cbc} * set ssh v2 macs {hmac-md5, hmac-md5-96, hmac-ripemd160, hmac-sha1-96} * set ssh {kerberos4, kerberos5, krb4, kerb5, k4, k5} * ssh key v1 * ssh key display /format:ietf * ssh v2 rekey ### Source Changes: * Fixed compatibility with the Open Watcom 2.0 fork * Added support for building with Visual C++ 2.0 * Added support for targeting Windows NT 3.50 with either Open Watcom 1.9 or Visual C++ 2.0 * Now builds on OS/2 with Open Watcom 1.9. Only minimal testing has been done. Networking does not work and the builds are done without optimisations. Further work is required, likely by someone with OS/2 development knowledge, to get it back to the Kermit-95 level of functionality. * OpenSSL 0.9.8 - 3.0.5 (the latest version) now works * Added support for TLS 1.1, 1.2 and 1.3 when built with sufficiently new versions of OpenSSL ## C-Kermit for Windows 10.0b4 beta 2 - 17 August 2022 This release focused on returning some level of SSH support. Initial efforts were based on using an external SSH implementation which resulted in fixes to the DLL, PTY and COMMAND network types. External SSH didn't work well enough in the end so focus shifted to built-in SSH using libssh. Support for some older Visual C++ releases (4.0 and 5.0) was added to enable RISC NT builds in the future (Visual C++ 4.0 was the last release to support MIPS and PowerPC), and Open Watcom 1.9 support was added to enable future OS/2 work. * Fixed builds with Visual C++ 14.x (2015-2022) * Fixed file transfer crash on builds done with Visual C++ 2008 and newer * Fixed builds with free versions of Visual C++ that don't include MFC * PTY support on Windows 10 v1809 and newer * Added Open Watcom 1.9 support (win32 target only) * Fixed building with Visual C++ 97 (5.0) * Fixed building with Visual C++ 4.0 * Fixed building with the free Visual C++ 2003 toolkit & Platform SDK * Fixed 64bit file seeking * Fixed detection of current windows releases * Fixed network DLL support (set network type dll) * Fixed file transfers when built with Visual C++ 5.0 and older * Removed ctl3dins.exe from the distribution (Windows defender thinks its malware) * Now uses modern windows UI widgets on XP and newer * Built-in SSH * Added support for resizing DLL and PTY terminals when the CKW terminal is resized ## C-Kermit for Windows 10.0b4 beta 1 - 17 July 2022 This release focused on tidying up the open-source Kermit 95 release of July 2011, getting it into a buildable state, and rebranding it as C-Kermit for Windows. No effort was made to replace features missing from the original open source release except for the GUI code (which was recovered and open-sourced in late 2013). It was based on C-Kermit 10.0 beta.04 and is best built with Visual C++ 6 though 7.0-8.0 (2002, 2003, 2005) do work too. * Upgraded from C-Kermit 8.0.207 to C-Kermit 10.0 beta.04. See the [C-Kermit 8.0.208 to 10.0b4 Change Log](https://www.kermitproject.org/ckupdates.html#ck100beta04) for more information on all that's changed there. * SRP support disabled * DECnet support disabled * LAT support disabled * Kerberos support disabled * SSH support removed * SSL support disabled * Other encryption features disabled * X/Y/Z modem support removed * OS/2 support disabled * Dialer removed * zlib support disabled * Fixed builds with Visual C++ 6 * Fixed builds with Visual C++ 7 * Removed 64bit file seeking - code was broken. * Removed licensing, registration and demo mode functionality * Reworked the About dialog * Fixed builds with Visual C++ 8 (2005) * Fixed builds with Visual C++ 7.1 (2003) * Fixed builds with Visual C++ 2010 and 2012 * Updated version number, copyright dates, icons * Changed application name from Kermit 95 to C-Kermit for Windows * Disabled DNS SRV support * Removed border from GUI dialog buttons * Unused KUI code deleted * Fixed the pipe command * Fixed URLs in the help menu * Dropped separate version number for C-Kermit on Windows * Updated Windows version check * Replaced "K95" with "CKW" in the status line and prompt ## Kermit 95 v2.2 - never publicly released Kermit 95 v2.2 was never publicly released, but [this file](https://www.kermitproject.org/k95-fixes-since-213.txt) documents what's new since Kermit 95 v2.1.3. Not every change for K95 v2.2 has made it in to Kermit 95 v3.0 due to the removal of some components that could not be open-sourced. In particular, changes for the Dialer in K95 v2.2 do not apply as the K95 3.0 dialer is based on K95 v2.1.2, and changes for the SSH subsystem don't apply to K95 3.0 as v3.0 uses an entirely new SSH implementation. In particular, the following entries from the K95 2.2 change log should be disregarded: * *Not implemented*: the dialer's QUICK command now supports connections based on templates and includes a SaveAs operation (a poor man's clone) ## Previous Kermit 95 releases Change logs going back to the release of the first version in October 1995 (1.1) * [1.1.21 to 2.1.3 Change Log](http://www.columbia.edu/kermit/k95news.html) - 2 April 2002 to 21 January 2003 * [1.1.20 Changes](https://groups.google.com/g/comp.protocols.kermit.announce/c/gpLy0vTV1Ug/m/hHFQqajRe98J) - 4 April 2000 ([k95news](https://web.archive.org/web/20010405154138/http://www.columbia.edu/kermit/k95news.html)) * [1.1.19 Changes](https://groups.google.com/g/comp.protocols.kermit.announce/c/uN9G8fp84nY/m/53HTzJvYQdgJ) - 17 February 2000 * 1.1.18 - Internal CU release * [1.1.17 Changes](https://groups.google.com/g/comp.protocols.kermit.announce/c/0mZIfP_LspA/m/cqLPWLsJiFYJ) - 21 June 1998 * [1.1.16 Changes](https://groups.google.com/g/comp.protocols.kermit.announce/c/8jaYcOv0cvo/m/Er5rCyp_xG8J) - 8 April 1998 * [1.1.15 Changes](https://groups.google.com/g/comp.os.ms-windows.announce/c/IDbj1Dl16aU/m/WmJlmGtSY5cJ) - 3 October 1997 * [1.1.14 Changes](https://groups.google.com/g/comp.protocols.kermit.announce/c/KWT_5sYXeC8/m/AGvXUCtXSh4J) - 25 September 1997 * [1.1.2 to 1.1.13 Change Log](https://web.archive.org/web/19970815161519/http://www.columbia.edu/kermit/k95news.html) - 24 July 1996 to 24 June 1997 * v1.1.11 of February 1997 restored OS/2 support replacing OS/2 C-Kermit 5A(191) * [1.1.6 Announce](https://groups.google.com/g/comp.protocols.kermit.announce/c/Yb8oikR0uuQ/m/kVDydxVQKT4J) - 18 July 1996 * [1.1.5 Announce](https://groups.google.com/g/comp.protocols.kermit.announce/c/L9wpCZEBw4Q/m/Y89bIR-wp3UJ) - 2 July 1996 * [1.1.2 to 1.1.4 Change Log (down the bottom)](https://web.archive.org/web/19970815161519/http://www.columbia.edu/kermit/k95news.html) - 18 December 1995 to 7 March 1996 * 1.1.1 - 3 November 1995: * Attempts to remove preloaded entries from Dialer caused a crash * Alphabetization of Dialer entries fixed not to be case-sensitive * Download directory specification in Dialer no longer ignored * Dial prefix no longer also treated as dial suffix by Dialer * Kermit BBS Dialer entry fixed to have Backspace key send Backspace * Range checking of various numbers by Dialer fixed * SET MODEM commands in K95CUSTOM.INI no longer ignored * Improved search technique for command files * Accuracy of Dialer status line online timer improved * ZMODEM downloads fixed to work when FILE COLLISION is BACKUP or RENAME * ZMODEM transfers fixed to work over various types of TELNET connections * Faster detection of lost connections during file transfer * 1.1 - First Release - 2 October 1995 * [OS/2 C-Kermit 5A(191)](https://www.columbia.edu/kermit/cko191.html) - 23 April 1995 * Last free release before it was renamed [Kermit 95 for OS/2](https://www.columbia.edu/kermit/os2.html), ported to Windows and sold commercially * [Binaries](http://www.columbia.edu/kermit/ftp/archives/cko191.zip) (source never released) * [OS/2 C-Kermit 5A(190)](https://www.columbia.edu/kermit/os2new.html) - 4 October 1994 * Last release to include 16-bit OS/2 1.x support * Last release for which source code was publicly available until the Kermit 95 2.2 code was open-sourced in 2011 * [Source](http://www.columbia.edu/kermit/ftp/archives/ckc190.zip), [Binaries](http://www.columbia.edu/kermit/ftp/archives/cko190.zip) * [OS/2 C-Kermit 5A(189)](https://groups.google.com/g/bit.listserv.os2-l/c/BSURfg2ufek/m/GjcIh14Jt_QJ) - 18 July 1993 * [OS/2 C-Kermit 5A(188) (update)](https://groups.google.com/g/comp.os.os2.apps/c/DesD23imeHI/m/I6-udyEnNhAJ) - 3 February 1993 * [OS/2 C-Kermit 5A(188)](https://groups.google.com/g/bit.listserv.i-amiga/c/DvS37Mfjj8s/m/sYYcpymJ3woJ) - 23 November 1992 * [OS/2 C-Kermit 5A(179)](https://groups.google.com/g/fj.kermit/c/rG6d5lpJilI/m/b94gm9h4XgIJ) - 14 February 1992 * OS/2 C-Kermit 4F(091) (OS/2 Kermit 1.00) - ??
