The permission rule wildcard syntax change from : to is the most impactful change for existing users. If you have custom permission rules in your settings files using the old syntax (e.g., Bash(git:)), the old format continues to work but new autocomplete suggestions and documentation now use the space-asterisk format (e.g., Bash(git )). Consider updating your rules to the new syntax for consistency.

The removal of the bundled Chalk template library and HTML5 tokenizer (parse5) from the CLI reduces the package size. These were replaced by lighter-weight alternatives or removed where unused.
