will add /opt/mycoolthing/bin to the beginning of $fish_user_path without creating duplicates,

- ``string match --regex`` now integrates named PCRE2 capture groups with fish variables, allowing variables to be set directly from ``string match`` (:issue:`7459`). To support this functionality, ``string`` is now a reserved word and can no longer be wrapped in a function.
|
||||
- Globs and other expansions are limited to 512,288 results (:issue:`7226`). Because operating systems limit arguments to ARG_MAX, larger values are unlikely to work anyway, and this helps to avoid hangs.
|
||||
- fish will now always attempt to become process group leader in interactive mode (:issue:`7060`). This helps avoid hangs in certain circumstances, and allows tmux's current directory introspection to work (:issue:`5699`).

- A new ``fish for bash users`` documentation page gives a quick overview of the scripting differences between bash and fish (:issue:`2382`).

Syntax changes and new commands

- Logical operators ``&&`` and ``||`` can be followed by newlines before their right operand, matching POSIX shells.

- When globbing, a segment which is exactly ``**`` may now match zero directories. For example ``**/foo`` may match ``foo`` in the current directory (:issue:`7222`).

you need a function to run any time ``read`` is invoked by a script,

use the new ``fish_read`` event instead (:issue:`7039`).

- ``status`` gained new ``dirname`` and ``basename`` convenience subcommands

- The ``type`` and ``_`` gettext functions are now implemented as a builtin for performance purposes (:issue:`7342`, :issue:`7036`).
|

- Broken pipelines are now handled more smoothly; in particular, bad redirection mid-pipeline
|

results in the job continuing to run but with the broken file descriptor replaced with a closed

- ``fish_greeting`` is now a function that reads a variable of the same name, and defaults to setting it globally. This removes a universal variable by default and helps with updating the greeting. However, to disable the greeting it is now necessary to explicitly specify universal scope (``set -U fish_greeting``) or to disable it in config.fish (:issue:`7265`).
