Minecraft 1.21.5 Support!

This release marks the first version compatible with Minecraft and Fabric 1.21.5. Please be aware that it may contain bugs; if you encounter any new issues, report them on the issue tracker. Exercise caution on servers with strict anti-cheat systems.

Besides the usual caution for early releases on new game versions, this update introduced significant changes to Minecraft's internal movement logic. As a result, some fundamental ViaFabricPlus patches broke, and I cannot guarantee full stability at this time.

Legacy API compatibility The api-legacy artifact has been removed and is no longer being shipped in 4.1.0+ builds of ViaFabricPlus.

Please read the v4.0.4 Changelogs for other changes as well

Bedrock 1.21.60 support!

Fixed container_close and take_item_entity packet errors; Please keep in mind that addressing these issues is particularly challenging, as Mojang introduces major technical rewrites even in minor updates.

Your financial support at https://florianmichael.de/donate is deeply appreciated and helps me continue working on this project to the best of my ability.

Technical Changes

• The project's artifact has been renamed from de.florianmichael:ViaFabricPlus to com.viaversion:viafabricplus.
• The source code package has been moved from de.florianmichael.viafabricplus to com.viaversion.viafabricplus.

Support for Jitpack has been removed. Please use the official ViaVersion repository instead.

• Stable API
  Mod authors should no longer depend on the core mod viafabricplus if they are only using the API. Instead, migrate to the viafabricplus-api artifact and update your code to use the general API endpoint.
  The API instance is now accessed via ViaFabricPlus#getImpl, which returns a ViaFabricPlusBase interface containing API functions. Refer to the detailed Javadocs or the updated development documentation for more information.

An example on how to include the api while still being able to run the mod would be:

modImplementation "com.viaversion:viafabricplus-api:4.0.0"
modRuntimeOnly "com.viaversion:viafabricplus:4.0.0"

• Legacy Compatibility
  Key internals from version 3.0.0 have been moved to the viafabricplus-api-legacy module. However, this submodule will be removed in future versions.
  The viafabricplus-api and viafabricplus-api-legacy modules no longer expose setting group holders. Instead, use ViaFabricPlus#getImpl#settingGroups to access specific setting instances.

User-Relevant Changes

• Settings
  The following debug settings have been removed:
  Send open inventory packet, Remove cooldowns, Send idle packet, Prevent entity cramming.

• Other
  Fixed blocking use delay in versions ≤ 1.8 (@lowercasebtw).
  Updated Polish translations (@Blayung).
  Updated Korean translations (@good7777865).
  Updated Simplified Chinese translations (@Andypsl8).

GitHub Repository Changes

• Visual / Low-Priority Features
  Visual-only features that are irrelevant to normal gameplay have been moved to a separate Fabric mod: viafabricplus-visuals. This mod is loaded by default but can be excluded if desired. This change simplifies updating the project to newer game versions.

• Organized Patches by Features
  All game modifications are now categorized as features. Each feature has its package under both features/ and injection/mixin/features/, organizing utility and mixin classes for easier project maintenance and porting. Refer to the updated maintenance documentation for further details.

Special thanks to @RaphiMC and all other contributors who have supported the project so far!

This release marks the first version compatible with Minecraft and Fabric 1.21.3. Please be aware that it may contain bugs; if you encounter any new issues, report them on the issue tracker. Exercise caution on servers with strict anti-cheat systems.

ViaFabricPlus for Minecraft 1.21

With this update, we are discontinuing support for Minecraft 1.21 and 1.21.1. We've implemented many bug fixes for 1.21.3 in the protocol library, allowing you to update the protocol translation code manually when using ViaFabricPlus 3.4.9 as follows:

1. Download the latest ViaBackwards .jar file from here.
2. Locate your Minecraft run folder (usually found in .minecraft for the default launcher or in your instance folder if using MultiMC).
3. Navigate to config/viafabricplus/jars and place the downloaded .jar file there.

Please be aware that these builds may become incompatible at any time. We recommend staying up-to-date with Mojang and Minecraft, and updating to 1.21.3 as soon as possible.

This update also fixes an issue with Ukrainian translations not loading correctly (thanks to @Darkhax).

Special thanks to @RaphiMC and @lowercasebtw for their help with this update! Apologies for the delay - maintaining and updating this mod is quite complex and time consuming.
