CHANGELOG: Reorganize a bit

Browse Source 
The builtin-buffering thing is huge and should be early in the big
ticket items, the performance improvement to completion of commands is
cool but not all that important.

@ -5,6 +5,12 @@ Notable improvements and fixes
------------------------------
- Undo and redo support for the command-line editor and pager search (#1367). By default, undo is bound to Control+Z, and redo to Alt+/.
- 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.
This makes it usable also for pipes where the previous command hasn't finished yet, like::
# Show all dmesg lines related to "usb"
dmesg -w | string match '*usb*'
- A new variable, ``fish_kill_signal``, is set to the signal that terminated the last foreground job, or ``0`` if the job exited normally (#6824).
- Control-C no longer kills background jobs for which job control is
disabled, matching POSIX semantics (#6828).

This makes it usable also for pipes where the previous command hasn't finished yet, like::
# Show all dmesg lines related to "usb"

- ``set`` and backgrounded jobs no longer overwrite ``$pipestatus`` (#6820), improving its use in command substitutions (#6998).
- Significant performance improvements to completions (#7153).
- The documentation is now presented in a new theme (#6500, #7371).
- ``fish --no-execute`` will no longer complain about unknown commands
or non-matching wildcards, as these could be defined differently at
runtime (especially for functions). This makes it usable as a static syntax checker (#977).
- ``type`` is now a builtin and therefore much faster (#7342).
Syntax changes and new commands
-------------------------------
- Range limits in index range expansions like ``$x[$start..$end]`` may be omitted: ``$start`` and ``$end`` default to 1 and -1 (the last item) respectively.
- Logical operators ``&&`` and ``||`` can be followed by newlines before their right operand, matching POSIX shells.
- A new ``fish_is_root_user`` simplifies checking for superuser privilege, largely for use in prompts (#7031).
Scripting improvements
----------------------
@ -58,9 +60,6 @@ Scripting improvements
- ``fish_indent`` now removes spurious quotes in simple cases (#6722)
and learned a ``--check`` option to just check if a file is indented correctly (#7251).
- ``pushd`` only adds a directory to the stack if changing to it was successful (#6947).
- ``fish --no-execute`` will no longer complain about unknown commands
or non-matching wildcards, as these could be defined differently at
runtime (especially for functions) (#977).
- Added a ``fish_job_summary`` function which is called whenever a
background job stops or ends, or any job terminates from a signal (#6959).
The default behaviour can now be customized by redefining this
@ -82,7 +81,6 @@ Scripting improvements
- ``complete`` takes the first argument as the name of the command if the ``--command``/``-c`` option is not used (``complete git`` is treated like ``complete --command git``), and can show the loaded completions for specific commands with ``complete COMMANDNAME`` (#7321).
- ``set_color -b`` (without an argument) no longer prints an error message, matching other invalid invocations of this command (#7154).
- Functions triggered by the ``fish_exit`` event are correctly run when the terminal is closed or the shell receives SIGHUP (#7014).
- ``type`` is now a builtin and therefore much faster (#7342).
- ``string replace`` no longer errors if a capturing group wasn't matched, instead treating it as empty (#7343).
- ``exec`` no longer produces a syntax error when the command cannot be found (#6098).
- ``disown`` should no longer create zombie processes when job control is off, such as in ``config.fish`` (#7183).
@ -90,7 +88,7 @@ Scripting improvements
- ``set --erase`` and ``abbr --erase`` can now erase multiple things in one go, matching ``functions --erase`` (#7377).
- ``abbr --erase`` no longer errors on an unset abbreviation (#7376).
- ``test -t``, for testing whether file descriptors are connected to a terminal, works for file descriptors 0, 1, and 2 (#4766). It can still return incorrect results in other cases (#1228).
- Trying to run fish scripts with Windows line endings (CRLF) produces a sensible error (#2783).
- Trying to run scripts with Windows line endings (CRLF) via the shebang produces a sensible error (#2783).
- An ``alias`` that delegates to a command with the same name no longer triggers an error about recursive completion (#7389).
Interactive improvements

- The Mercurial prompt correctly shows untracked status (#6906).
- The ``fish_vcs_prompt`` passes its arguments to the various VCS prompts that it calls (#7033).
- The Subversion prompt was broken in a number of ways in 3.1.0 and has been restored (#7278).
- A new helper function ``fish_is_root_user`` simplifies checking for superuser privilege (#7031).
