⛈ Issues while updating?

If you encounter a problem during update, please check this collection of the most common issues encountered over the past couple of release cycles first, and test if the included fixes solve your problem.

♻ Changes

✨ Improvements

• Explicitly declare in-memory storage for rate limiter. Gets rid of warnings under latest flask-limiter versions.

🐛 Bug fixes

• #4656 - Fix cookie suffix creation on the frontend to properly work with multi-level subpaths. The wrong suffix caused OctoPrint's core UI not to be able to extract the CSRF token when running behind a reverse proxy with a multi-level prefix path, rendering the UI non functional.
• #4659 - Fix the sanity check on the backup download API so that backups created through the CLI or third party plugins named arbitrarily will be downloadable by admins.
