Changelog — v0.1 (Initial Release)

Release date: September 11, 2026
Minecraft version: 1.20.1
Modloader: Forge

Added

• Initial release of the SMP Qc420 modpack with 323 mods installed and configured.

• Performance mods installed and tuned for smoother rendering (Embeddium and related rendering pipeline mods).

• Foliage/leaf optimization mods installed (CullLessLeaves, Optileaves) to reduce leaf render load while keeping foliage detail.

• Core survival multiplayer mods and content expansions (building, decoration, exploration, tech, and magic mods) added to give players a full progression experience.

• Base server configuration set up for private SMP play among friends.

Changed

• N/A (first release — no prior version to compare against).

Fixed

• Resolved startup mixin conflicts between CullLessLeaves and Embeddium/Optileaves so the modpack now boots cleanly on server start.

• Addressed server payload-limit errors encountered during initial setup to ensure stable client-server communication with a large modlist.

Known Issues

• Some mod interactions may still need further balancing as more players join and test the pack.

• Future versions will introduce additional content, further optimization passes, and bug fixes based on in-game testing.

Notes

This is v0.1 of SMP Qc420 — more versions and mod additions will follow. Enjoy the pack!
