CraftEngine 26.9.2

• 26.3 support
• Improved chunk loading logics for paper 1.21.4+
• Improved resource pack optimization speed
• Fixed mcmeta not generated when using bbmodels

• Further optimized CraftEngine's handling logic for item packet. Now some client-bound-data will not be applied in certain scenarios, reducing Netty thread pressure without affecting any gameplay content. This is very effective for scenarios where hundreds of players are engaged in PvP simultaneously.
• Fixed client bound data not applied to items in shelves on chunk packet sent

Important
After updating to this version, please do not roll back.
This version officially introduces the resource pack workflow design. Please be sure to update your resource pack hosting configuration. Workflows let you control when and how resource packs are generated, packaged, uploaded, and sent. They make it easier to test changes before publishing, integrate tools like PackSquash and BlueMap, and run only the steps you need, while keeping the default setup simple.

• Introduced the resource pack workflow and added packsquash support.

CraftEngine 26.5 – A Big Update!

This is a major update for CraftEngine. From now on, versions will follow a year.month.revision format.

We’ve made over 80,000 lines of code changes and more than 600 commits, so instead of a long changelog, please check the wiki to see what’s new.

A few important things to know:

• stem_block now has a filter for the block below it. Check the wiki to update your settings, or use the new default config to fix melon stem issues.
• The feature placer changed a lot back in version 26.1. If you want to keep using the default feature config, please extract the updated default config file.
• There are many API changes in this update – and they’re stable enough to support updates for the next whole year.
