Kusama v0.7.11
Hotfix release for the issue described at https://medium.com/@gavofyork/kusamas-first-adventure-2cd4f439a7a4
This introduces reversion and black-listing logic to allow blocks to be marked bad and be reverted (assuming that the state is still available).
It marks block 0x15b1b925b0aa5cfe43c88cd024f74258cb5cfe3af424882c901014e8acd0d241
as bad (Kusama block #516510) and forces it and all others after it to be re-authored.
It also introduces a time warp; specifically, the wall clock time after 2020-01-07 09:00:00 GMT will be 247,788 seconds (around 69 hours) in the past, but will proceed at 6 times the speed of real-time until it equal real-time at which point standard wall-clock behaviour will take over. This will happen 41,289 seconds (around eleven and a half hours) later at around 20:28 GMT on the same day.
It also includes a number of additional features and fixes, including support native runtime execution for both the provisional Polkadot mainnet and Kusama.
