This patch release contains 4 cherry-picked changes to address the mainnet attestation processing issue from 2025-12-04. Operators are encouraged to update to this release as soon as practical. As of this release, the feature flag --disable-last-epoch-targets has been deprecated and can be safely removed from your node configuration.
A post mortem doc will full details is expected to be published later this week.
--ignore-unviable-attestations (replaces and deprecates --disable-last-epoch-targets) to drop attestations whose target state is not viable; default remains to process them unless explicitly enabled. [PR]
