Changes for Minecraft 1.21 players

Changes from Wurst 7.46.2

By default, MobSpawnESP will no longer filter out dark spots that are too small for any mobs to spawn, as this filter was found to crash the game sometimes. (/d/841)
Added a "Hitbox check" setting to MobSpawnESP, allowing you to re-enable the filter for dark spots that are too small. The "Unstable" option matches MobSpawnESP's old behavior, while "Slow" is a new version of the filter that shouldn't cause any crashes but significantly slows down the game compared to "Unstable".
Fixed a some weird colors appearing in the sky when Navigator's main screen is open.
Added automated end-to-end testing similar to the client_test that Fabric API does. Every time the code changes, GitHub Actions will actually run Wurst, do some basic things with it, take screenshots along the way, and report back if anything goes wrong. If for whatever reason you want to run this test yourself, you can do so by adding the JVM argument -Dwurst.e2eTest.

Changes from Wurst 7.46.3

Fixed X-Ray not working if you use Fabric API 0.110.5 in Minecraft 1.21.4 or 1.21.4-rc3. As a result of this fix, older Fabric API versions are no longer supported in the affected Minecraft versions.
If you somehow obtain a stack of multiple totems of undying, AutoTotem will now count them correctly.
Fixed ServerFinder skipping over some servers when checking if they work. (#1086)
.give and .itemlist now display the same error message if a given item name is invalid.
.give can now place the given items anywhere in your inventory, not just in the hotbar.
Fixed .give not working and added a test to make sure that won't happen again.
Fixed .copyitem not working and added a test to make sure that won't happen again.
Added a test for the .modify command.

Changes from Wurst 7.46.4

Fixed a compatibility issue with Sodium 0.6.1. Sodium 0.6.0 remains supported too. (#1088)
Dropped support for Sodium 0.4 and 0.5, which don't actually exist for modern Minecraft versions anymore.

Changes from Wurst 7.46.5

Fixed NoFall not working in Minecraft 1.21.4. (#1092, /d/891)
Added a test for NoFall, so next time a snapshot breaks it, we'll know before that Minecraft update is released.
Updated to Fabric API 0.112.0+1.21.4.
Updated to Gradle 8.11.1.
Updated to Loom 1.9.

Changes from Wurst 7.46.6

Fixed a crash in Minecraft 1.21.1 when breaking a block in survival mode or seeing a piston retract. This crash was caused by of X-Ray's mixins, which was broken in a very subtle way that neither the automated mixin audit nor the manual X-Ray testing caught. (#1095, /d/923, /d/924, /d/926, /d/927, /d/933)
Fixed Freecam's fake player being invisible when you enable it for the first time. (#1096, #1098)
Breaking a block in survival mode, watching a piston extend and retract, and using X-Ray are now part of the automated test suite.

Note: Since these changelogs are taken directly from previous Wurst updates that did not originally support these Minecraft versions, they might sometimes not make sense in this context.
