  • ✨ Additional pack updates and changes may come throughout the 26.3 beta cycle.

🧪 Beta Notice

26.3-1.0.0-beta is an early beta release.

Because Minecraft 26.3 is a new major game version for the pack, compatibility is still being worked on.

More mods may be temporarily removed, re-added, updated, or changed as development continues.

💾 Important — Back Up Your Worlds

⚠️ Please back up your important worlds before updating to OptiFabricium 26.3-1.0.0-beta.

Before updating:

  1. 🗂️ Close Minecraft completely.
  2. 💾 Make a copy of your saves folder.
  3. 📁 Store the backup somewhere outside your Minecraft instance.
  4. 🔒 Keep the backup until you've confirmed the new version works correctly.
  5. ✅ Only delete the backup once you're confident your worlds are safe.

Do not rely on the modpack itself to protect your worlds. Keep your own backup of any world you care about.

📌 Final Note

Minecraft 26.3 — Wilderness Bound has arrived, and OptiFabricium is beginning its next development cycle.

This is only the first beta, so expect more changes, mod updates, re-additions, and improvements throughout the 26.3 cycle.

More updates coming soon! ⚡
