see version client_2.2.0 changelog

i got tired of the incompatibilities between common mods and Roughly Enough Items.

Create and Ars Nouveau do not have their specialized crafting prompts represented in the REI GUI, as well as multiple other examples (Farmers' Delight, etc.).

see 2.1.1 changelog

there is a recipe conflict between Only Hammers and Excavators and Quark.

if you tried to craft a stone hammer (2 sticks, 2 stone, 1 cobble), Quark adds recipes that allow crafts of vanilla stone tools out of any variety of stone (including smelted cobble[stone], andesite, diorite, etc.), so that recipe would give you the stone pickaxe instead of a stone hammer.

this is the version to use for a dedicated server.

it removes mods (i.e. visuals-only, client-side dependencies, etc.) that would cause a server not to function.
