The center of this proposal is a batch call which authorizes the runtime upgrades v0.5.1 and v0.5.2, but the latter is authorized approximately 24 hours (7200 blocks) after the former to provides some time to execute the upgrade. Both of those upgrades have already been tested on Battery Station for a couple of weeks and are running stable. The upgrades have been withheld on mainnet because there have been some issue with transaction fee payment with currencies other than ZTG, but this issue has been resolved by now.
