Soon after the V11 update (which I think was a very buggy one), comes V126.96.36.199 and it brings fixes to some bugs and improves performance and stability.
According to All About Symbian, the update is available on Nokia Software Updater and Over The Air. but I cant seem to get the update when I check on device updates OTA. Probably it is regional based.
This is the screen you will see if you try to get the update via Nokia Software Updater.
Check out TheNokiaBlog‘s video on the changes/improvements from the V12 update.
So have you got your V12 yet? 😀
