22.0

No softfork changes. The version before Steem release 22.1 which contained the patch described in GitHub here. Note: this version is compatible with 22.1.

22.1

No softfork changes. The clean version before all the "drama".

22.2

Softfork changes implemented by a super-majority of witnesses to prevent Tron's accounts from voting on witnesses, voting on content, voting on SPS proposals, powering down, and transferring stake. Details here.

22.3

My version of the soft-fork which prevented Tron from voting for witnesses, but did not block them from doing anything else. Details here.

22.333

Hive account@therealwolf's version. See his comment in reply to this post.

22.4444

Non-Tron witnesses running the same code as 22.1 (no softfork) but in symbolic protest of Tron's hostile takeover.

22.5

Tron witnesses running the same code as 22.1 (no softfork) who were put in place by Tron + exchanges as part of a hostile takeover.
