2022-01-25: Nonce Error Hotfix

This release fixes a critical bug in l2geth’s nonce handling logic that could have caused a denial-of-service. The fix has been rolled out across both Kovan and mainnet, as well as to all major infrastructure providers. If you are running a replica, please upgrade l2geth to version 0.5.8 as soon as possible. No funds were ever at risk, and the issue was never exploited.

For full details of what went wrong, see the Nonce Error Hotfix Post-Mortem.

This release also deploys last week’s timestamp changes to mainnet and performs a bunch of routine upgrades.
