Avid have just released Pro Tools 12.5.1 which by the looks of the release notes is one rather epic bug fix release.
Its great to see Avid apparently squashing so many bugs in one hit and this is rather promising if its a sign of things to come.
If you had been experiencing issues with Pro Tools 12.5 take a look at the fix list below and see if your issues have been addressed.
The update should be appearing in you Avid accounts and Application Manager over the next few days if it's not there already.
