We've just released v1.22.0! 

This is mostly a maintenance release and now includes our electra fork work compatible up to consensus specifications v1.5.0-alpha.4 for testing excluding light client specifications. Some minor performance optimizations are included such as deserializing a single state tree at startup rather than two separate trees, shortening startup time. This is a **low priority** update.

For the full changelog, please see:
