Fabulously Optimized plans to discontinue distributing MultiMC versions on CurseForge, starting with v6.0.0.

FAQ

Why?

• The new CurseForge site layout is making it significantly harder for MultiMC and vanilla users to download there
• Due to #626, the version of MultiMC is already missing Sodium as of 4.8.1, and it is expected to miss more mods in the future
• These were never "server packs" but some users got confused
  • On the other hand, only "server packs" made them visible in the first place
• Removing that version simplifies the building and approval process on CurseForge
• MultiMC has now fixed the Modrinth issues with its latest 0.7 release
• Vanilla users are getting a #110 soon
• Pretty sure mod devs were never getting compensated when posted there
• Probably easier to make #462 work too
• Recently some approvals were unpredictably pushed for manual approval due to a Fabric Language Kotlin update (which is already updated on CF itself...)

When?

MultiMC users are right now no longer encouraged to download from CurseForge.

The deprecation itself will happen on Minecraft 1.21.

Edit: now vanilla instructions have been updated.

What does it mean to users?

Awesome news! No, really:

• MultiMC users will be able to download with a few clicks now
• Vanilla users will be able to download with a few clicks as well
• Mods and FO get the download counts they deserve on Modrinth
• No confusion about "server packs" because there never were any

Really, no drawbacks at all?

Okay, there are some. But very minor:

• Vanilla users will no longer be able to download FO manually. In terms of FO, that is actually still a good thing, as it means there will be less users who download and install just the mods, which is a very wrong thing to do. No longer the case
• It may affect FO's download count and monetization on CurseForge a bit, but also maybe not at all
• Pojav support may be slightly harder to do in the future, though not necessarily (if there is some kind of installer that can run on it) Pojav now has a modpack installer

While the new installer is not here yet, I've made a new page for vanilla user downloads, which downloads the pack and its mods directly from Modrinth and combines to a simple ZIP file.
The install instructions have been updated for 4.11.0+, with legacy ones available below.

CurseForge uploads for MMC Legacy will continue at least until (excluding) FO 6.0.0-alpha.1.

6.0.0-alpha.1 removed the already deprecated MMC format. If everything goes as planned it won't be present in stable

Completed with 6.1.0.
