Steam Update Notes
Patch notes released on Steam carried a more comprehensive version of the same message:
- Product Update - Valve
- Updates to Borderlands have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:
- Adds DLC Support: Ensure Cross Compatibility between owners of ClapTrap’s New Robot Revolution content with those who do not own the New Revolution content.
- Stops removing valid weapons and items: Some legitimately-obtained items and weapons were being inaccurately tagged as invalid or hacked, and were being deleted from players’ inventory. The patch ensures that only invalid weapons & items are deleted.
