7. Get the correct length of delivered message when the state synchronization is correct;

8. Fixed the issue resulted from RPC concurrence;

9. Fixed the deadlock issue of testing p2p simulator;

10. Fixed the issue that when block hashes search log, the search result is simulator;

11. Fixed the issue that the empty STATICCALL accounts on other networks besides Ethereum haven’t been deleted;

12. Canceled the limit of file descriptor 2048, applied the system maximal limit instead;

13. Fixed the bug of prestate tracer;

14. Fixed the slice panic of downloader;

15. Added the legitimacy verification of “txpool.config”;

16. Fixed “hasher not returned to pool” issue;

17. Modified the rule that ethapi get nonce from txpool;

18. Fixed the bug that the version number must be integer;
