EOSIO-explorer v1.2.0

EOSIO v2.0.5

On April 21, 2020 we released EOSIO v2.0.5. Updates in this release include security, stability, and other changes.



  • Addressed a time-out issue with trace_api_plugin as it is very likely that the default value of http-max-response-time-ms must be increased for large blocks
  • Fixed potential leak in OC’s wrapped_fd move assignment operator

Other Changes:

  • Added compressed file support for trace_api_plugin to reduce redundancy in the data stream
  • Changed the RPC call v1/trace_api/get_block to allow for asynchronous HTTP support and the get_block command to run on the configurable http-threads pool as opposed to the main application thread
  • Merged changes on the develop branch to 2.0.x
