- `bind` has a new `--silent` option to ignore bind requests for named keys not available under the current `$TERMINAL` (#4188, #4431)
- Globs are faster (#4579)
- `string` reads from stdin faster (#4610)
- `string split` supports `-n/--no-empty` to exclude empty strings from the result (#4779)
- `cd` tab completions no longer descend into the deepest unambiguous path (#4649)
- Setting `$PATH` no longer warns on non-existent directories, allowing for a single $PATH to be shared across machines (e.g. via dotfiles).
- `funced` now has a `-s` and `--save` option to automatically save the edited function after successfully editing (#4668).

\subsection string-split "split" subcommand
`string split` splits each STRING on the separator SEP, which can be an empty string. If `-m` or `--max` is specified, at most MAX splits are done on each STRING. If `-r` or `--right` is given, splitting is performed right-to-left. This is useful in combination with `-m` or `--max`. Exit status: 0 if at least one split was performed, or 1 otherwise.

If `-r` or `--right` is given, splitting is performed right-to-left. This is useful in combination with `-m` or `--max`. With `-n` or `--no-empty`, empty results are excluded from consideration (e.g. `hello\n\nworld` would expand to two strings and not three). Exit status: 0 if at least one split was performed, or 1 otherwise.
