This release contains a few important bug fixes and improvements for Minecraft 1.17.1.

Highlights

• Improved frame rates when loading or updating chunks.
• Fixed a memory leak caused by sync objects never getting released.
• Added options to control how many threads are used for chunk building, and to always defer chunk updates for improved frame times. The default number of threads used for chunk building is more optimally chosen and should help improve frame rates on slower CPUs.
• Improved the precision of the compressed vertex format, reducing texture glitches found with some texture packs and vanilla blocks
• The inner faces of leaves are no longer rendered if fast graphics are enabled, significantly reducing the geometry count of scenes with lots of foliage (thanks ADudeCalledLeo.)
• Config file handling has been greatly improved, and if a corrupted config file is found, the user will be prompted to fix the problem instead of the game crashing.

And everything else...

• Mods which provide config file overrides will no longer crash on first startup (thanks tbejos.)
• Improved our shader code slightly to reduce overhead in the vertex stage, potentially helping older graphics cards.
• Improved compatibility with the legacy AMD graphics drivers on Windows.
• Fixed a problem where empty draw calls would be submitted during chunk rendering.
• Some other minor improvements and fixes...
