xonsh/xonsh 0.12.5 on GitHub

Added:

Autoloadable xontribs
Support for f-glob strings (e.g. ``fg`{prefix}*```)
Now xontribs support loading and unloading <https://github.com/xonsh/xonsh/issues/4541>_
with functions _load_xontrib_(xsh: XonshSession, **kwargs) -> dict,
_unload_xontrib_(xsh: XonshSession, **kwargs) -> None defined in their module.
Updated doc <https://xon.sh/tutorial_xontrib.html>_
Added a special '$LAST_RETURN_CODE' environment variable to access the return code of the last issued command. (Only set during interactive use).
New prompt-customization fields: 'last_return_code_if_nonzero', 'last_return_code'.
Documented the HISTCONTROL ignorespace option

Changed:

![] now returns a HiddenCommandPipeline when run with a background command (e.g. ![sleep 10 &])
Extended whole_word_jumping xontrib with matching bindings for
delete and backspace. The XONSH_WHOLE_WORD_CTRL_BKSP environment
variable can be set to False to avoid binding control+backspace in
incompatible terminals.
The default prompt (on unix-systems) now includes a red [] field in case a command failed.
New docs theme furo
completions from fish are now filter based on the current prefix.

Removed:

xontrib prompt_ret_code is now removed.
Now the default prompt already shows the last-return-code when the previous command fails.
Please use the new prompt fields last_return_code, last_return_code_if_nonzero from
the PR <https://github.com/xonsh/xonsh/pull/4798>_

Fixed:

Using fg for commands started in the background (e.g. ![sleep 10 &]) now works
SIGHUP (instead of SIGKILL) is sent to unfinished jobs when exiting the shell. This allows the nohup command to work properly.
bg now properly resumes jobs in the background
ExecAlias now sets the returncode of a command correctly
Empty/comment-only commands no longer get added to the history
On prompt-toolkit, when there is a job like sleep 500 & running in the background, pressing Ctrl+D twice to force quit now works properly
Environment Variables are now completed correctly when in quotes
Silence spurious errors on exit due to out-of-order cleanup
