Deprecations and removed features

• The default fossil prompt has been disabled (#12342).

Interactive improvements

• The bind builtin lists mappings from all modes if --mode is not provided (#12214).
• Line-wise autosuggestions that don’t start a command are no longer shown (739b82c34db, 58e7a50de8a).
• Builtin history now assumes that PAGER supports ANSI color sequences.
• fish now clears the terminal’s FLUSHO flag when acquiring control of the terminal, to fix an issue caused by pressing ctrl-o on macOS (#12304).

New or improved bindings

• Vi mode word movements (w, W, e, and E) are now largely in line with Vim. The only exception is that underscores are treated as word separators (#12269).
• New special input functions to support these movements: forward-word-vi, kill-word-vi, forward-bigword-vi, kill-bigword-vi, forward-word-end, backward-word-end, forward-bigword-end, backward-bigword-end, kill-a-word, kill-inner-word, kill-a-bigword, and kill-inner-bigword.
• Vi mode key bindings now support counts for movement and deletion commands (e.g. d3w or 3l), via a new operator mode (#2192).
• New catpuccin-* color themes.

Improved terminal support

• set_color learned the strikethrough (--strikethrough or -s) modifier.

For distributors and developers

• The CMake option WITH_GETTEXT has been renamed to WITH_MESSAGE_LOCALIZATION, to reflect that it toggles localization independently of the backend used in the implementation.
• New cargo xtask commands can replace some CMake workflows.

Regression fixes:

• (from 4.1.0) Crash when autosuggesting Unicode characters with nontrivial lowercase mapping (#12326, 78f4541116e).
• (from 4.3.0) Glitch on read --prompt-str "" (#12296).
