According to various sources in the Steem Network, Steemit plans a secret hard fork of the Steem network. This is because the source code had been hidden from public view and review and the Steemit group had been very secretive and no public announcement had been made on the Steemit blog either.
One of the rumors seem to imply that this hardfork will be to change the power down time for Steem to 30 days (which was one of the proposals made by Steemit Inc)
According to Blocktrades:
However, this forced Blocktrades to discontinue its support for STEEM on May 19, 2020. Sources say that the hardfork will happen on May 20.
