@ -19,6 +19,12 @@ Notable improvements and fixes
Although flow control remains off by default, enterprising users can now enable it for external commands with
``stty`` (#2315).
- A new ``fish_add_path`` helper function to add paths to $PATH without producing duplicates, to be used interactively or in ``config.fish`` (#6960).
For example::
fish_add_path /opt/mycoolthing/bin
will add /opt/mycoolthing/bin to the beginning of $fish_user_path without creating duplicates,
so it can be called again and again from config.fish or just once interactively, and the path will just be there, once.
- ``fish_preexec`` and ``fish_postexec`` events are no longer triggered for empty commands.
- The ``test`` builtin now better shows where an error occured (#6030).
- builtins may now output before all data is read. For example, ``string replace`` no longer has to read all of stdin before it can begin to output.
