Mandatory UpdateThis is an emergency update for all core desktop wallet users running 5.0.0 or lower.
A vulnerability with the budgeting system was discovered and has been fixed (PR 2137).
This release also contains a protocol upgrade (to 70921).
Users will need to update their clients before enforcement of this update goes into effect.
Update enforcement is currently scheduled to go into effect at the same block height that was scheduled for v5.0.0: 2700500
Masternodes will need to be restarted once both the masternode daemon and the controller wallet have been upgraded.
Important NoteNo user's funds are at risk if you don't upgrade in time.
However, users facing a checkpoint error after upgrade need to resync the chain.
