- blockpool moves to its own package - uses errs pkg for its own coded errors - publicly settable config of params (time intervals and batchsizes) - test helpers in subpackage - optional TD in blocks used now to update peers chain info - major improvement in algorithm - fix fragility and sync/parallelisation bugs - implement status for reporting on sync status (peers/hashes/blocks etc) - several tests added and further corner cases covered
