xonsh 0.16.0 on Python PyPI

Added:

Square brackets can now be used in command arguments without quotes (e.g. echo a[b])
Add XONSH_BASH_PATH_OVERRIDE option (off-by-default) to override what is
returned by xonsh.platform.bash_command.
Added PATH.prepend(path) to add path to the beginning.

Changed:

Xonsh AppImage now on Python 3.12 that works faster.
Xonsh AppImage: pinned prompt-toolkit version until fix upstream issue.
Builtin aliases (xontrib, history) switched to threadable mode.
EnvPath methods (append, remove, add, insert) prepare the path before action.
Replaced black formatter with ruff-format <https://docs.astral.sh/ruff/>_
source_foreign_fn now does not run subshells in interactive mode, so
associated RC files like zshrc and bashrc will not be auto-loaded on
sourcing.

Removed:

Removed ArgParserAlias.hook_pre_add_argument, ArgParserAlias.hook_post_add_argument.
Please use custom action instead to modify the argument options.
Removed deprecated module xonsh.proc
Removed usage of deprecated cgi module

Fixed:

Fixed an issue with completions when using absolute paths to commands and having $UPDATE_COMPLETIONS_ON_KEYPRESS set to True. #5127
Jobs: fixed "index out of range" exception.
Expressions like 2>1 are now parsed correctly as Python code instead of being treated like special io-redirection operators.
Redirect tokens in quotes (e.g. ">", "2>", "2>1") are now correctly passed to commands as regular arguments.
Fixed NotADirectoryError during load dircolors.
Fixed a bug that caused xonfig web to overwrite its own configuration file. See #5297
If an error is encountered while loading the xonshrc file, the traceback is now output as plain text rather than as a list of Tokens

Authors:

xonsh.AppImage excluded from this release because of #5364.
