Chestifier

First release for the 1.21.2-1.21.4 line. Minecraft changed its rendering and inventory APIs several times across 1.21.x, so the code for 1.20.5 does not run on 1.21.2, and the code for 1.21.11 does not run there either. This release ports Chestifier to the API used by 1.21.2 through 1.21.4.

Fixes for this Minecraft version

• Fixed the frozen-slot markers rendering in the corner of the screen instead of behind the items in your hotbar.
• Fixed the button icons appearing washed out, and item count numbers flickering or fading in and out while a chest was open.
• Fixed a crash on startup caused by a render hook that no longer exists in 1.21.2.

Inherited fixes and hardening

Carried over from the 0.1.3 release:

• Fixed a crash when the highlight color in the config was invalid: it now falls back to the default instead of crashing the render every frame.
• Fixed a crash risk when sorting/matching against a chest with zero slots.
• Fixed a latent bug in the enchantment sort comparison that could throw under certain inventory states.
• Corrupt/unreadable config files are now backed up to chestifier.json.bak before falling back to defaults, so a bad config no longer silently destroys your settings.
• The search box no longer leaks its text/focus state between different opened chests.
• Errors from optional third-party mod integrations are now logged properly instead of being silently swallowed.
• Various internal cleanup: shared layout constants, deduplicated code, clearer naming.
