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.
Detailed Version Guide
This pack uses a continuous, global versioning system. Every release follows this format:
<major>.<minor>.<build>[-channel]
Examples:
2.5.6— stable2.5.7— hotfix for2.5.62.6.0-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.
