EOSIO Version 1.2.0 Release: MongoDB Plugin Enhancements, Community Plugin Integrations, and Replay Optimization

Today we are pleased to release the next incremental version of EOSIO, V1.2.0. You can view the detailed release notes here on Github, and find documentation on the EOSIO Developer Portal.

The MongoDB Plugin in V1.1 could be used instead of the history plugin for get_actions and get_transactions. The V1.2 release extends the functionality of the mongo_db_plugin to include get_key_accounts and get_controlled_accounts, both of which can be stored in the existing accounts collection document.
