- Use password field for bot token and client secret values in the admin panel.
- Add a per-server "Kick user if they are no longer in allowed user groups" flag.
- Fix old sync long entries not being pruned as expected.
- When modifying the XenForo user-group to Discord role mappings, only trigger a re-sync for the affected server to avoid excessive API calls.
Note that some functionality mentioned as being included in the 2.8.4 release was not actually included so this release resolves that.
