Release 4.0.2

As mentioned in
https://github.com/fish-shell/fish-shell/pull/9688#discussion_r1155089596,
commit b77d1d0e2b (Stop crashing on invalid Unicode input, 2024-02-27), Rust's
char type doesn't support arbitrary 32-bit values.  Out-of-range Unicode
codepoints would cause crashes.  That commit addressed this by converting
the encoded bytes (e.g. UTF-8) to special private-use-area characters that
fish knows about.  It didn't bother to update the code path in builtin read
that relies on mbrtowc as well.

Fix that. Move and rename parse_codepoint() and rename/reorder its input/output
parameters.

Fixes #11383

-fish 4.0b1 (released December 17, 2024)
+fish 4.0.2 (released April 20, 2025)
+====================================
+
+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 (:issue:`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 (:issue:`11277`, :issue:`11290`).
+- Key combinations using the super (Windows/command) key can now (actually) be bound using the :kbd:`super-` prefix (:issue:`11217`). This was listed in the release notes for 4.0.1 but did not work correctly.
+- :doc:`function <cmds/function>` is stricter about argument parsing, rather than allowing additional parameters to be silently ignored (:issue:`11295`).
+- Using parentheses in the :doc:`test <cmds/test>` builtin works correctly, following a regression in 4.0.0 where they were not recognized (:issue:`11387`). 
+- :kbd:`delete` in Vi mode when Num Lock is active will work correctly (:issue:`11303`).
+- Abbreviations cannot alter the command-line contents, preventing a crash (:issue:`11324`).
+- Improvements to various completions, including new completions for ``wl-randr`` (:issue:`11301`), performance improvements for ``cargo`` completions by avoiding network requests (:issue:`11347`), and other improvements for  ``btrfs`` (:issue:`11320`), ``cryptsetup`` (:issue:`11315`), ``git`` (:issue:`11319`, :issue:`11322`, :issue:`11323`), ``jj`` (:issue:`11046`), and ``systemd-analyze`` (:issue:`11314`).
+- The Mercurial (``hg``) prompt can handle working directories that contain an embedded newline, rather than producing errors (:issue:`11348`).
+- A number of crashes have been fixed. Triggers include prompts containing backspace characters (:issue:`11280`), history pager search (:issue:`11355`), invalid UTF-8 in :doc:`read <cmds/read>` (:issue:`11383`), and the ``kill-selection`` binding (:issue:`11367`).
+- A race condition in the test suite has been fixed (:issue:`11254`), and a test for fish versioning relaxed to support downstream distributors' modifications (:issue:`11173`).
+- Small improvements to the documentation (:issue:`11264`, :issue:`11329`, :issue:`11361`).

+fish 4.0.1 (released March 12, 2025)
+====================================
+
+This release of fish includes the following improvements compared to fish 4.0.0:
+
+- Key combinations using the super (Windows/command) key can be bound using the :kbd:`super-` prefix (:issue:`11217`).
+- Konsole's menu shows the "Open folder with" option again (:issue:`11198`).
+- ``$fish_color_search_match`` will now only be applied to the foreground color if it has an explicit foreground. For example, this allows setting::
+    set -g fish_color_search_match --reverse
+- Cursor shape commands (``\e[2 q``) are no longer sent in non-interactive shells or in redirections (:issue:`11255`).
+- :doc:`status <cmds/status>` gained a ``is-interactive-read`` subcommand, to check whether the script is being called from an interactive :doc:`read <cmds/read>` invocation.
+- fish's background tasks are now started in a way that avoids an error on macOS Terminal.app (:issue:`11181`).
+- Using key combinations within qemu should work correctly.
+- Prompts containing control characters no longer cause incorrect display of command lines (:issue:`11252`).
+- Cancelling the command-line in Vi mode displays correctly again (:issue:`11261`).
+- The acidhub prompt properly displays the git branch again (:issue:`11179`).
+- Completions for ``wine`` correctly include files again (:issue:`11202`).
+- On macOS, paths from ``/etc/paths`` and ``/etc/manpaths`` containing colons are handled correctly (:issue:`10684`). This functionality was included in the 4.0.0 release notes but was missing from the source code.
+- The XTerm ``modifyOtherKeys`` keyboard encoding is no longer used under WezTerm, as it does not work correctly in all layouts (:issue:`11204`).
+- kbd:`option-left` and other similar keys should now work in iTerm versions before 3.5.12; the kitty keyboard protocol is now disabled on these versions (:issue:`11192`).
+- The kitty keyboard protocol is no longer used under Midnight Commander, as it does not work correctly (:issue:`10640`).
+- fish now sends the commandline along with the OSC 133 semantic prompt command start sequence. This fixes a test in the kitty terminal (:issue:`11203`).
+- Git completions for third-party commands like "git-absorb" are completed correctly again (:issue:`11205`).
+- Completions for ``diskutil`` no longer produce an error (:issue:`11201`).
+- The output of certain error messages no longer prints newlines to standard output (:issue:`11248`).
+- A number of crashes have been fixed, including file names longer than 255 bytes (:issue:`11221`), using fish on a btrfs filesystem (:issue:`11219`), history files that do not have the expected format (:issue:`11236`), and pasting into an empty command line (:issue:`11256`).

    - ``bind ctrl-x,alt-c 'do something'`` binds a sequence of two keys.
 
    Any key argument that starts with an ASCII control character (like ``\e`` or ``\cX``) or is up to 3 characters long, not a named key, and does not contain ``,`` or ``-`` will be interpreted in the old syntax to keep compatibility for the majority of bindings.

 - fish can now be built as a self-installing binary (:issue:`10367`). That means it can be easily built on one system and copied to another, where it can extract supporting files.
   To do this, run::

-- :kbd:`ctrl-c` during command input no longer prints ``^C`` and a new prompt, but merely clears the command line. This restores the behavior from version 2.2. To revert to the old behavior, use ``bind ctrl-c __fish_cancel_commandline`` (:issue:`10213`).
 - Bindings can now mix special input functions and shell commands, so ``bind ctrl-g expand-abbr "commandline -i \n"`` works as expected (:issue:`8186`).

-- ``stderr-nocaret`` was introduced in fish 3.0 (and made the default in 3.3). It makes ``^`` an ordinary character instead of denoting an stderr redirection, to make dealing with quoting and such easier. Use ``2>`` instead. This can no longer be turned off since fish 3.5. The flag can still be tested for compatibility, but a ``no-stderr-nocaret`` value will simply be ignored.
-- ``qmark-noglob`` was also introduced in fish 3.0 (and made the default in 3.8). It makes ``?`` an ordinary character instead of a single-character glob. Use a ``*`` instead (which will match multiple characters) or find other ways to match files like ``find``.
-- ``regex-easyesc`` was introduced in 3.1. It makes it so the replacement expression in ``string replace -r`` does one fewer round of escaping. Before, to escape a backslash you would have to use ``string replace -ra '([ab])' '\\\\\\\\$1'``. After, just ``'\\\\$1'`` is enough. Check your ``string replace`` calls if you use this anywhere.
-- ``ampersand-nobg-in-token`` was introduced in fish 3.4. It makes it so a ``&`` i no longer interpreted as the backgrounding operator in the middle of a token, so dealing with URLs becomes easier. Either put spaces or a semicolon after the ``&``. This is recommended formatting anyway, and ``fish_indent`` will have done it for you already.
-- ``remove-percent-self`` turns off the special ``%self`` expansion. It was introduced in 3.8. To get fish's pid, you can use the :envvar:`fish_pid` variable.
