Iron Oak

Iron Oak now runs on Minecraft 26.3.

This is a port, not a feature update — the same mod as 1.3.0+26.2, rebuilt for 26.3. That is why the version stays 1.3.0.

Minecraft 26.3

• Built for 26.3 with Fabric Loader 0.19.5 and Fabric API 0.160.7.
• Requires Java 25.
• Works on a dedicated server as well as in single player.

Still on 26.1 or 26.2?

Stay on 1.3.0+26.2. This build will not load on 26.2 — Minecraft 26.3 reshaped the worldgen feature API, so the jar genuinely needs 26.3. Nothing is missing from the 26.2 build; it is the same mod, and it stays available and maintained.

Same for the older lines: 1.21.11 → 1.3.0+1.21.11, 1.21.1 → 1.3.0+1.21.1.

Under the hood

Nothing a player will notice, listed so the change is not mistaken for a behaviour change: 26.3 collapsed ConfiguredFeature into Feature, which meant rewriting all six tree generators, and cookingtime became a required field on cooking recipes — the burning and washing recipes now state it explicitly at the same 200 ticks they always used.

The infused-tree growth path was walked in-game before release.
