• Fixed #597; prompt shows leftover text sometimes (regression introduced in v1.6.10).
• Fixed #596; it's easy to forget whether Enter in history list executes or inserts.

• Added os.setalias() for setting a doskey alias without needing to invoke the doskey.exe program.
• Fixed a case where match descriptions could be displayed with incorrect padding and truncation (regression introduced in v1.6.6).
• Lua debugging enhancements:
  • Changed the built-in embedded scripts to include debug info, which allows some Lua error messages to be more useful for troubleshooting.
  • Added srcmap command in the Lua debugger to override where to find source files.

• Added an optimization to further reduce flicker when re-drawing the prompt.
• Added a user_data.shared_user_data table to allow linked argmatchers to share data with each other while an input line is being parsed (see Responding to Arguments in Argmatchers for details).
• Fixed #579; popup lists could accidentally truncate text in the first column when there's only one column.
• Fixed #576; setup exe doesn't remove old uninstall exe files.
• Fixed #575; error when color.executable is set and color.unrecognized is not (regression introduced in v1.6.2).

• Fixed #574; prompt.spacing "eats" lines containing Unicode Surrogate Pairs such as for some nerdfont icons (Windows Terminal accidentally returns that such lines are empty).
• Fixed #573; C# was unable to read Clink's version resource.
• Fixed #555; security advisory CVE-2020-24370 for a Lua bug.

v1.6.8

• Fixed #571; error in clink.bat under some circumstances (regression introduced in v1.6.7).

v1.6.7

• Recognize the little-known cmd /r as a synonym for cmd /c so that Clink can optimize and skip injecting into a cmd /r process.
• Fixed displaying descriptions when they're left-justified (regression introduced in v1.6.6).
• Fixed argmatcher:chaincommand("run") to not find argmatchers for builtin CMD command names (since CMD doesn't get invoked in that case, so it won't get interpreted as a CMD command).
• Fixed argmatcher:chaincommand() to find an argmatcher for a builtin CMD command even if a directory exists with the same name (since CMD interprets that case as a CMD command).
• Fixed argmatcher:chaincommand("cmd") so when exec.aliases is enabled it can include aliases as completions.
• Fixed argmatcher:addarg({loopchars="+", etcetc}) so that -Q:+x still gets parsed into two input words -Q: and +x.
• Fixed to parse foo^ bar as two words "foo" and "bar".
• Fixed to recognize ^echo (etc) as a builtin CMD command name despite embedded ^ characters.
• Fixed #570; fixed #569 more thoroughly, and cd /d cannot be used anywhere because it also requires command extensions.

• Fixed #570; fixed #569 more thoroughly, and cd /d cannot be used anywhere because it also requires command extensions.

• Added clink history --no-show-time to allow omitting history timestamps even when the history.time_stamp setting is show.
• Fixed match display to not right justify descriptions when the screen isn't wide enough or when descriptions contain aligned columns (like clink set completions do since v1.6.3).
• Fixed clink history when output is redirected; strip any escape codes that might be embedded in the time format.
• Fixed #569; cmd /e:off causes syntax error in clink.bat script.
• Fixed #567; clink history compact accidentally deletes all timestamps.
• Fixed documentation error in Lua API Reference about "w" mode in io.open() and io.sopen() (the behavior was correct, but the documentation was inaccurate/unclear).

• Added all match fields in the table of matches passed to the clink.onfiltermatches() callback function.
• Fixed stripping colors from strings (e.g. when displaying in popup lists); it didn't strip 8-bit and 24-bit colors correctly.

NOTE: This release includes changes that enable clink-gizmos's FZF integration to show nerd fonts file icons in completion lists. See the README file there for more info. It also requires using dirx.

• Added rl_buffer:hassuggestion() and rl_buffer:insertsuggestion() for direct access to inserting suggestions without invoking Readline commands.
• Added clink.dirmatchesexact() and clink.filematchesexact() which are the same as the non-exact variants, except these don't append a * to the search pattern. For example, clink.filematchesexact("*.zip") can collect exactly "*.zip" file matches instead of "*.zip*".
• Added OS version info to clink info.
• Added UNC share name completion when using Executable Completion (the exec.enable setting).
• Fixed completing input . or .. when the exec.enable setting is enabled.
• Fixed applying colored-completion-prefix when match display filtering is active or a match has a custom display field.
• Fixed the exec.path setting so it doesn't accidentally include directories if their names end with an executable extension such as .exe.
• Fixed finding an argmatcher registered with a full path (e.g. c:\foo\bar.exe) when a full path is entered without a drive letter (e.g. enter \foo\bar.exe).
• Fixed #562; clink autorun install strips quotes by mistake.

• Breaking Change: For the four Ctrl-- key combinations, Clink got the Shift key backwards and generated inaccurate input codes. And that broke the Readline/bash default key binding for undo (the Windows default key binding of Ctrl-z works fine). If your .inputrc file has bindings for any of the Ctrl-- key combinations then you can keep the keys working the same by updating the key bindings. You can even use the $if clink_version >= 1.6.3 syntax in your .inputrc file to make it define the key bindings differently in different versions of Clink.

  Key Combination	Old Code	New Code
  Ctrl--	"\C-_" or C-_	"\e[27;5;189~"
  Ctrl-Shift--	"\e[27;6;189~"	"\C-_" or C-_
  Ctrl-Alt--	"\e\C-_" or "\M-\C-_" or M-C-_ or etc	"\e[27;7;189~"
  Ctrl-Alt-Shift--	"\e[27;8;189~"	"\e\C-_" or "\M-\C-_" or M-C-_ or etc

• Completions for all clink set settings include the current value in the description field (e.g. type clink set Alt-= to see Clink settings and their current values).
• Fixed to differentiate between undo and vi-undo commands again (they do the same thing, but are technically different commands).
• Fixed execute-named-command to also accept Ctrl-- for undo (the emacs binding for undo).
• Fixed redisplaying multi-line prompts after using completion during execute-named-command.
• Fixed accidentally loading the history file twice on each prompt; now it loads once, as intended.
• Fixed another double-free and potential crash in the Readline library; after navigating through history entries and then editing a history entry, pressing Ctrl-c or Ctrl-Break could cause a crash or memory corruption (regression exposed by changes in Readline 8.2).
• Applied fixes for 6 Lua bugs, curated by @goodusername123 (thank you!) from Lua.org:
  • "Dead keys with nil values can stay in weak tables."
  • "Expression list with four or more expressions in a 'for' loop can crash the interpreter."
  • "Label between local definitions can mix-up their initializations."
  • "Return hook may not see correct values for active local variables when function returns."
  • "Suspended __le metamethod can give wrong result."
  • "Wrong code generated for a 'goto' followed by a label inside an 'if'."
• Fixed the Lua debugger so 5-digit line numbers don't break indentation when showing source code lines.
