v2.2.0.5
UI - Fix UI behaviour for upgrading expired witness accounts
UI - Improve UI behaviour for displaying 'extend' button for witness accounts
UI - Add/Fix "Ctrl+L" shortcut to clear debug console text
RPC - Make 'renewwitnessaccount' command work also for upgrading witness accounts
CORE - Restore 'first' mining address for those miners whose address was changed to a new one by buils containing the issue that was fixed in 2.2.0.3 release
CORE - Improve mining behaviour for v2 transactions, insert an extra nonce, this is unlikely to matter at current mining speeds in any way but is better for correctness anyway. (Only really relevant in fringe cases like mining with -limitdeltadiffdrop=0)
