We released a new version of excavator:
https://github.com/nicehash/excavator/releases/tag/v1.5.4a

- added lyra2z
- fixed lyra2rev2 bug that was causing lower pool speed on some pools
- added state.set method to API: https://github.com/nicehash/excavator/tree/master/api#state-set

The purpose of state.set method is easier handling with excavator between switching. See example:
