Sublime Text build 4213 brings Python 3.14 support and syntax highlighting improvements

Sublime Text has released build 4213, marking a significant milestone for the popular code editor with the addition of Python 3.14 support. The update brings modern scripting capabilities to developers who rely on Sublime Text's plugin ecosystem, aligning the editor with the latest version of Python's runtime environment. This upgrade comes as welcome news for maintainers of syntax highlighting packages and build systems that depend on embedded Python execution.

The release also includes Python 3.3, though the legacy interpreter is now disabled by default and slated for removal in a future version. Users experiencing plugin compatibility issues with the newer Python 3.14 host can temporarily re-enable Python 3.3 through the disable_plugin_host_3.3 setting. This transitional measure gives plugin authors and users time to adapt their extensions before the older runtime is phased out entirely. Beyond the Python updates, the official changelog lists additional categories for API, platform-specific improvements across Windows, Mac, and Linux, performance enhancements, and various fixes.
