Fabric modifies Minecraft's class files using and its fork of Spongepowered Mixin.

Fabric is highly modular and is composed of several elements, most of which can be found in the GitHub organization.

More Information

Fabric's first version was made available in 2016, but the toolchain wasn't ready for mass usage until 2018 when it was released officially.

Since then, Fabric has updated to every Minecraft version (including "snapshot" versions) in a relatively quick time span.

asiekierka stepped down from Fabric development sometime during July/August of 2019. modmuss50 has continued developing FabricMC.
