Minecraft Forge 1.20.2

What's new in this version:

New:
- New, rewritten networking
- Better support for proxies such as Velocity and BungeeCord
- Drastically simpler architecture and implementation
- Packets are now records
- Make SimpleChannel use a varInt for the discriminator allowing essentially unlimited packets
- Use official mappings for in-repo patches, will be converted to SRG during build
- Send known channels to the server when they send us theirs
- Optimise `ForgeRegistry#validateContent`
- Optimise and clean-up BackgroundScanHandler code
- Optimise path filter in mod loading
- Make default Entity.getAddPacket automatically use Forge's enhanced spawn packet if necessary.
- This spawn packet needs to be re-designed, it is effectively only there to hook into creating the new entity instance. This will be re-evaluated during the clean-up in 1.21+
- Clean-up FMLLoader and Launch Handlers
- New test suite
- Test mods are now treated as their own jars, as well as having their mods.toml auto-generated. No more mods.toml conflicts!
- Add pattern matching support to Data run mod list
- Rewrite our GameTest hooks to be more sane
- Add game test to GlobalLootModifierTest which validates the smelting modifiers
- Revive ConditionalRecipe and ConditionalAdvancement
- Also directly add conditional support to all vanilla recipe data generators
- Revive custom ingredient types.
- Add a CrashReportAnalyser that tries to identify the mod that crashed the game
- This feature scans your crash report as it is being generated and lists suspected mods that could be the cause of the crash, accounting for coremodding as well.
- This makes it easier to find the culprit as it is often listed clearly in the crash report itself (e.g. "Suspected mods: buggymod")
- Improve mod loading error message for errors inside mod constructors
- No longer shows a vague error if the error happens inside a constructor - Forge now tells you the actual error
- Optimise registries by using fastutils collections to minimize boxing
- Significantly faster builds with large clean-up and reorganization. Skip redundant decomp/recomp step on CI
- Gradle 8.4
- Datagen addOptionalTag/s methods that allow passing the TagKey itself instead of passing the location
- Add ClientPauseEvent

- Improve mod description formatting in mods screen
- No longer fussy about indentation in mods.toml files
- Fixes the [CR] text being shown for some mods
- Updated to use newer libraries that reduce the amount of command line arguments needed to run the game.
- Fix issues in the SecureModule's classloader that caused resources to not be seen when they are on parent module layers.
- Make Ingredient check for invalidation on getItems(), invalidate ingredients on tags update
- Fix texture UV values for obj models
- Fix tag loading being unordered
- Add more sanitization to the ChannelListManager to further improve support for third-party modded servers and proxies
- Move Chunk Watch/Unwatch events to fire after sync packets have been sent to the client
- This makes sure that modders who send extra chunk data will have clients who know about the chunk.
- Fix rare crash with early display window, fixes #9673
- Don't turn off VSync when rendering from Minecraft context
- Fix KeyModifiers not being properly taken into account
- Rework KeyModifiers system to properly allow keybinds to be triggered when multiple modifiers are pressed.
- Fix setting keybinds whel using keyboard inputs to select the menu
- Fix LoadingErrorScreen inner headers are not centered
- Fix TagLoader error not printing tag name correctly

Removed/deprecated:
- Removed FakePlayer system, it's broken and needs a major rewrite
- This was removed as it frequently had edge-cases that gave a false sense of security and was a bit of a "wack-a-mole" game to find and fix issues with each MC version
- Deprecate EntityRenderersEvent.AddLayers functions that hard case to LivingEntityRenderers as the backing maps do not guarantee that type
