Features
Improved LSL script performance for regions with many idle scripts
Known Issues
In certain cases, Premium Plus users can still be charged for mesh uploads after crossing a region boundary (server#2565). If the estimated upload cost appears as nonzero, returning to the previous region or teleporting to a far-away region is a workaround.
There are still some cases in which P2P chat conversations can hit session initialization failures (server#2573)
