- Syntax highlighting for Python files using uv as script runner in shebang #3689 (@janlarres)
## Bugfixes
- Quote filenames before substituting them into `$LESSOPEN` / `$LESSCLOSE` templates, preventing shell injection when a filename contains shell metacharacters, see #3726 (@curious-rabbit)
- Fix `--list-themes` unconditionally probing the terminal via OSC 10/11 even when `--theme` was set to an explicit value, see #3700 (regression introduced in bc42149a). (@optimistiCli)
- Fix inverted `$LESSCLOSE` warning so bat warns on nonzero exit, not on success. See #3654 (@cuiweixie)
- Sanitize control characters in filenames before displaying them in the file header, error messages, and the terminal title, preventing ANSI escape injection via crafted filenames. Closes #3054, see #3691 (@curious-rabbit)
