The Steemit blockchain team has officially released version 0.21.0 of Steem also known as Hardfork 21 which contains code for adding a Worker Proposal System to Steem (called the Steem Proposal System or Steem.DAO) and the Economic Improvement Proposal to Steem.

Exchanges

As this is a planned hardfork of the Steem blockchain, exchanges that are operating Steem exchange nodes should upgrade as soon as possible so that there is no interruption of services when the hardfork is expected to occur on the 27th of August, 2019. Note that this is contingent on supermajority adoption by the Steem witnesses of the suggested upgrade, as is always the case with hardforks.
