How do I change or update the Forge version specifically?

Forge is version-sensitive: your mods are built against a particular Forge build, so choosing the right one matters. Here's how to change or update Forge specifically.

Choosing the right Forge build

Use the Software page, choose Forge (or NeoForge), then select the exact Minecraft version and Forge build you need — rather than accepting the latest.

If your modpack targets a specific Forge build, match it exactly — mods are built against a particular Forge version.

Step-by-step

1. Open the Software page.
2. Choose Forge (or NeoForge).
3. Select the exact Minecraft version and Forge build your pack needs.
4. Install (your world is kept) and Start from the Console.

For a build not offered, run the Forge installer's server files and set server.jar accordingly.

Warning: Don't just take the latest Forge build if your modpack targets a specific one — a mismatch will cause mods to fail or crash on boot.
