This is *hopefully* the last hotfix as I work to get the new desktop player stable for all users.

If you have not used MPV Shim and were unable to use the new Desktop client, this release fixes the issue. The problem was that the authorization wasn't working properly, but for all previous MPV Shim users, the old one made the application appear to work. If video played inside web player window, didn't seem to support advanced codecs, or the "cast" icon didn't indicate the player was connecting to the backend, you were affected.

**You will need to log out from the web client and log in again for the application to work properly if you used a broken version.**

If you have launched a broken version of the desktop client within the past 12 hours, you will need to clear your cache. (This will not be needed in newer releases.) Open a command prompt or terminal and enter:

- Windows: `rd /s /q %appdata%\jellyfin-mpv-shim\cache`
- Linux: `rm -r ~/.cache/jellyfin-mpv-desktop/`

This is another bug fix release to hopefully make the desktop client usable for more people. The renderer has been switched from EdgeHTML (Microsoft Edge) to CEF (Google Chrome). This should make the application behave better, but unfortunately it doubles the download size. The new version also remembers how it was positioned and sized on the screen.


This release should fix an issue where the desktop client is starting with a blank screen.
