• Added new suggestionlist.hide_hints setting to control whether to hide input hints while using the suggestion list (input hints are normally controlled by the comment_row.show_hints setting, and are hidden by default while using the suggestion list).
• Added a type-ahead optimization in popup lists to avoid redundant or unnecessary processing during incremental find or filter input.
• Improve command line parsing to recognize when an executable exists with the same name as a built-in CMD command (e.g. "echo.exe") and predict whether CMD will run the built-in CMD command or the executable file. This affects argmatchers, completion, and input line coloring.
• Changed Clink's built-in updater to verify digital signatures before applying an update.
• Fixed position of highlights in the suggestion list to consistently use the earliest matching position.
• Fixed #835; Unicode input is garbled in popup lists (regression introduced in v1.8.0).
• Fixed edge cases where certain Unicode input could be misinterpreted in popup lists and in clink-select-complete.
• Fixed potential for a buffer overread if invalid UTF8 bytes are encountered.
• Internal logging improvements.
