This version fixes the known issue from last version where “latest block” request may fail. Now we only expose through RPC the blocks that are saved in storage. Several fixes for fast-sync stability, and fixes for the failing test from the Ethereum Testing suite are also included. There is a refactor of PoWMiningCoordinator for EthashMiner and the Keccak-256 miner.
