EDIT: Released BuildCraft 6.2.6, which does an urgent update to the RF API (fixes newest CoFH mods, Ender IO?) and fixes a crash bug with fluids. Sorry!

For Developers

The builder API and the gate APIs have a few changes, namely, the builder API got a refactor and IStatementParameter has some extra functions yu need to implement. However, I believe the API should stay fully stable from now on for the foreseeable future.
