This release of fish fixes a number of issues identified in fish 4.0.1:

• Completions are quoted, rather than backslash-escaped, only if the completion is unambiguous. Continuing to edit the token is therefore easier (#11271). This changes the behavior introduced in 4.0.0 where all completions were quoted.
• The warning when the terminfo database can’t be found has been downgraded to a log message. fish will act as if the terminal behaves like xterm-256color, which is correct for the vast majority of cases (#11277, #11290).
• Key combinations using the super (Windows/command) key can now (actually) be bound using the super- prefix (#11217). This was listed in the release notes for 4.0.1 but did not work correctly.
• function is stricter about argument parsing, rather than allowing additional parameters to be silently ignored (#11295).
• Using parentheses in the test builtin works correctly, following a regression in 4.0.0 where they were not recognized (#11387).
• delete in Vi mode when Num Lock is active will work correctly (#11303).
• Abbreviations cannot alter the command-line contents, preventing a crash (#11324).
• Improvements to various completions, including new completions for wl-randr (#11301), performance improvements for cargo completions by avoiding network requests (#11347), and other improvements for btrfs (#11320), cryptsetup (#11315), git (#11319, #11322, #11323), jj (#11046), and systemd-analyze (#11314).
• The Mercurial (hg) prompt can handle working directories that contain an embedded newline, rather than producing errors (#11348).
• A number of crashes have been fixed. Triggers include prompts containing backspace characters (#11280), history pager search (#11355), invalid UTF-8 in read (#11383), and the kill-selection binding (#11367).
• A race condition in the test suite has been fixed (#11254), and a test for fish versioning relaxed to support downstream distributors’ modifications (#11173).
• Small improvements to the documentation (#11264, #11329, #11361).
