[ziogaschr]

This release includes an important fix for a miner DoS vulnerability, where an attacker could toggle mining intermittently by broadcasting statuses with fake total difficulties. All users are recommended to upgrade to this version or later.

What's Changed

• Spiral hardfork activation values for ETC mainnet are configured per spec. Block 19_250_000, eta January 31, 2024.
• MESS (ECBP1100) is scheduled to deactivate coincidentally with the Spiral hard fork.

Fixes

• Fix miner auto-pause vulnerability (#596)

Does MESS deactivate on Mordor at the same block as mainnet?

[meowsbits]

No... in fact, Mordor doesn't have any specification or implementation yet to deactivate it. That's a good TODO, though.
