 - Syntax highlighting for Python files using uv as script runner in shebang #3689 (@janlarres)
 
 ## Bugfixes
+- Report `BAT_CONFIG_DIR` in `bat --diagnostic`, so bug reports show a config directory that overrides `$XDG_CONFIG_HOME`. See #4068 (@ump45nose)
 - Exit quietly with status 0 instead of panicking when stdout is closed early (broken pipe) on auxiliary output paths such as `--completion`, `--config-file`, `--diagnostic`, `--generate-config-file`, `--set-terminal-title` and `cache --build`/`--clear`, matching the main output path since #232, closes #4034, see #4035 (@Mathjk)
 - Track strikethrough (SGR 9 / 29) in the ANSI style tracker so it is re-emitted like bold, dim, italic, and underline, and is no longer dropped after the first highlighted token when displaying ANSI input with syntax highlighting, see #4015 (@mikehasa)
 - Allow boolean flags to be given more than once, so that a flag set in the config file can also be passed on the command line without erroring, see #3912 (@logarithmone1128)
