+            - **Fixed Offline Game Launch**: Removed upstream's check that blocked offline accounts from launching the game unless at least one Microsoft account was signed in. Offline accounts can now launch directly with 0 Microsoft accounts required.
             - **Rebased onto Official Upstream 2.3.1**: Integrated all upstream OneLauncher 2.3.1 updates, fixes, and performance improvements.
             - **Offline / Cracked Accounts**: Full offline account support with customizable username and avatar caching.
             - **Custom Offline Skins & targeted multiplayer injection**: Custom 3D skin changer, per-account UUID hash targeting preventing multiplayer skin cloning, and automatic CustomSkinLoader config generation.
