OptiFabric Origins (1.14.4 & 1.15.2)
These are the old versions of 1.14.4 and 1.15.2 OptiFabric, updated to work again with the latest Fabric Loader and latest supported Fabric API. I've used code and fixes from later versions of the official OptiFabric to patch these older ones. Full credit goes to modmuss50 for creating OptiFabric and Chocohead for maintaining it, without them this wouldn't have been possible.
