Detailed Version Guide

OptiFine for Fabric uses a structured versioning system. Every release follows this format: **`[.[.]][-channel[.]]`** Examples: - `2.5` — stable - `2.5.1` — hotfix for `2.5` - `2.6-alpha.1` — first alpha release for a seperate Minecraft version The version number describes **the pack itself**, not the Minecraft version. Minecraft compatibility is shown separately on Modrinth. --- ## Version Number Breakdown ### Major — `` Large updates to the pack. This number only increases when the pack undergoes a significant redesign or major feature shift. ### Minor — `` Normal updates within a major version. This increases when the pack receives meaningful improvements, mod additions, compatibility changes, etc. ### Build — `` A patch‑level counter **within the same Minecraft version**. This number increases when the pack receives bug fixes or small adjustments for that specific Minecraft version. This number **resets when Minecraft updates**, because each Minecraft version starts its own patch sequence. Examples: - `2.5` → Minecraft 1.21.1 (stable release) - `2.5.1` → Minecraft 1.21.1 (first patch)j - `2.5-alpha.1` → Minecraft 1.21.2 (first alpha build) - `2.5-beta.2` → Minecraft 1.20.1 (second beta build) Build numbers simply indicate bug fixes and other minor changes tied to Minecraft versions. --- ## Release Channels Channels appear after a dash. - `-dev` — Experimental development builds. Unstable and incomplete, highly likely to not even work. - `-alpha` — Early testing builds. Features may be missing or broken. - `-beta` — Feature‑complete testing builds. Mostly stable. - **No suffix** — Stable release and/or hotfix. Fully tested and recommended. Recency is shown by the dot and the number. - A channel followed by `.` indicates the senority of the build. For example: - `-alpha.1` indicates the first alpha build - `-dev.3` indicates the third dev build - `-beta.4` indicates the fourth beta build --- ## Choosing the Right Version - Use the **latest stable** version for your Minecraft version. - Only use **alpha**, **beta**, or **dev** builds if you need early access or want to help test. Minecraft compatibility is shown on Modrinth, while the version number reflects the evolution of the pack itself.
