Important Information About Pro Tools CS Updates
Avid Technical Support recommends that in general, only the Pro Tools users experiencing the specific problems listed in the documentation on these pages should use the following CS updates. In some cases, a CS update may be recommended for all users to avoid potential problems.

These CS (for customer support) releases are provided as interim Pro Tools releases to address the specific issues described. While our testing has not shown these changes introduce other problems, fixes in CS versions have not been fully qualified by Avid unless otherwise noted. New features or changes to existing features are sometimes included with CS updates, and those additions (unlike other fixes) are generally qualified.

All Pro Tools CS Updates are cumulative, meaning the most current CS version available for any Pro Tools release will also include all fixes from all previous CS versions for that Pro Tools release.
