All the Mods 10 version 8.3 dropped on October 15, advancing the NeoForge loader to 21.1.259 while remaining on Minecraft 1.21.1.
The pack continues its kitchen-sink model: one download that bundles several hundred mods covering tech, magic, exploration, automation and building. Players get a pre-tested combination instead of assembling and debugging their own list.
Loader Update from 8.2
Version 8.2, released September 22, used NeoForge 21.1.251. The step to 21.1.259 is the main documented change. The hosting blog notes this difference affects startup configuration and recommends reading the release notes rather than swapping only a few files.
Client and Server Downloads Differ
The main download, All the Mods 10-8.3.zip, is for the client launcher. Servers require the separate ServerFiles-8.3.zip from the Additional Files section on CurseForge; it is listed at roughly 1.2 GB. Using the client archive on a server produces missing files or version errors. Stop the server, back up the world and configs, test the new pack on a copy, then update. Confirm the loader version matches before inviting players back.
