BitShares (BTS) community members issued the “Statement of the Association on the Upgrade of Version 4.0-To All Witnesses”, which stated that the Association has developed a version 4.0 patch program, which aims to restore the voting system to the version before 4.0 To eliminate adverse effects. This patch only fixes changes that have not been added privately without community voting, and does not affect the normal use of other functions of version 4.0. The statement called on all witnesses to install the patch. After the witness installs the patch file, the patch file will automatically take effect at 21:55, August 20, Beijing time. The core developer abit proposed to perform a hard fork at the same time the patch file takes effect.
