This release updates Developer's Toolkit to 1.21.10 and ships a BUNCH of utility changes and more!

This modpack release will likely require a full configuration reset; an incredible amount of mods were swapped for variants or removed due to version compatability.

The size of the pack has massively been reduced. We now only include 61 mods in comparison to the 113 of the original 1.2.1 release. This is for both performance reasons as well as to make the pack easier to update going forward.

All major utilities are still bundled or have been consolidated. You are encouraged to install mods for specific use-cases yourself.

We've officially migrated to Simply Optimized as our base pack due to issues during the 1.21.5 release cycle.
