This is a RELEASE CANDIDATE for version 1.9.0. The latest STABLE release is v1.8.2.

The eosio.system and eosio.bios contracts contained in this release can only be deployed on an EOSIO blockchain after the activation of the WTMSIG_BLOCK_SIGNATURES consensus protocol upgrade.

System contract

The system contract tracks a variable (total_activated_stake) to determine the first moment when 15% of all stake has voted so that it can trigger full activation of the system's features. After activation occurs, this variable is no longer needed. In previous releases, this variable continued to be updated even though it no longer had a purpose or even a well-defined meaning after activation. Furthermore, checks within the code that enable full functionality still referred to this variable. Since manipulation of this variable could potentially have adverse effects on the operation of the system contract, this release prevents further updates to the variable after activation and avoids depending on its value in the logic of the code after activation (#400).

Dependencies

This release depends on eosio.cdt v1.7.x and (optionally) on eosio v2.0.x. To compile the contracts in this release, first install eosio.cdt v1.7.0-rc1. To also compile the unit tests, first build and install eosio v2.0.0-rc2. The eosio.bios and eosio.system contracts in particular also require that the WTMSIG_BLOCK_SIGNATURES consensus protocol upgrade has been activated on the EOSIO blockchain before they can be deployed.
