What version should I use?

To get the correct version of OptiFine for Fabric for your setup:

1. Open the Versions tab.
2. Click Game versions.
3. Select the Minecraft version you want to play on.
4. Choose the latest stable release (the newest version without a suffix like -alpha, -beta, or -dev).

How to compare versions:
Pick the version with the highest numbers from left to right. For example:

• 3.4.1 is newer than 2.5.3
• 3.5.2 is newer than 3.4.1

If no stable releases exist for your Minecraft version, you may use a dev, alpha, or beta build, but these may contain bugs or missing features.

A detailed explanation of the versioning system is available below.

This pack uses a continuous, global versioning system. Every release follows this format:

<major>.<minor>.<build>[-channel]

Examples:

• 2.5.6 — stable
• 2.5.7 — hotfix for 2.5.6
• 2.6.0-alpha — alpha release

The version number describes the pack itself, not the Minecraft version. Minecraft compatibility is shown separately on Modrinth.

Version Number Breakdown

Major — <major>

Large updates to the pack.
This number only increases when the pack undergoes a significant redesign or major feature shift.

Minor — <minor>

Normal updates within a major version.
This increases when the pack receives meaningful improvements, mod additions, compatibility changes, etc.

Build — <build>

A global release counter.
Every release (alpha, beta, release, etc.) uses the next available build number.

This number does not reset when Minecraft updates.
It also does not stay tied to a specific Minecraft version.

Examples:

• 2.5.6 → Minecraft 1.21.1 (stable release)
• 2.5.7-alpha → Minecraft 1.21.2 (alpha release)
• 2.5.8 → Port to Minecraft 1.20.1 (stable release)
• 2.5.9 → Minecraft 1.21.1 (patch)

Build numbers simply increase as the pack evolves.

Release Channels

Channels appear after a dash and never inside the numeric version.

• -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.

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.
• Hotfixes for older Minecraft versions will always use the next global build number.

Summary

This versioning system:

• Keeps version numbers simple and continuous
• Works cleanly across all Minecraft versions
• Avoids branching or resetting numbers
• Makes prerelease channels obvious
• Ensures every build has a unique, chronological version

Minecraft compatibility is shown on Modrinth, while the version number reflects the evolution of the pack itself.
