2.4.3 is out too!
It’s recommended especially for OAuth2 users.
The auto updater should also update you in the next weeks/days.

thank you,
Markus (for the sync client team)
PS: Note that the 2.5.0 beta1 is out too. It has a new interesting feature called “virtual files” which allows you to get the full file tree without the actual contents. The file content gets synced down on double click. Download it from https://github.com/owncloud/client/releases/tag/v2.5.0-beta1 or switch to the ‘beta’ channel in the settings of your 2.4.3 client.
