Full Changelog: v5.4.21...5.4.22

BepInEx 6.0.0-pre.1

NOTE: This is a pre-release of a major version of BepInEx. BepInEx 5 plugins will not work with this release yet.

About upgrading

This release is mainly meant for those who use current Bleeding Edge builds to mod Il2Cpp games. If you want to use this release, follow this upgrade guide:

• If you use BepInEx 5: Stay on BepInEx 5! The current pre-release does not support loading BepInEx 5 plugins, and there are many issues.
• If you use BepInEx Bleeding Edge builds (builds 577 and lower): It is recommended that you upgrade to this pre-release to ensure all your plugins keep working. All builds after 6.0.0-be.577 will not be compatible with newer BE builds. To upgrade, simply download the appropriate ZIP below and replace your old files with the new ones.
• If you want to mod new Unity Mono games: Consider using BepInEx 5! The API is still stable, and BepInEx 6 will eventually include support for loading BepInEx 5 plugins!
• If you want to mod new Il2Cpp games: Consider using Bleeding Edge builds! Builds after 6.0.0-be.577 use updated tooling and .NET 6 for Il2Cpp. This pre-release is mainly meant for those who already have existing Il2Cpp plugins and can't upgrade at the moment.
