Integrations

Major Changes

This release introduces the new secure upgrade feature as described in the spec. With this mechanism, off-chain code changes in eigenda-proxy can now be executed in a hardfork-style manner. Logic prior to the activation block remains backward compatible, while only the new logic is executed after the activation time.

As part of the secure upgrade mechanism, the recency window is now hardcoded in eigenda-proxy, and can be updated via secure upgrades going forward. The current configured value is 48 hours. Please also see hokulea release note.

This release also includes useful improvements that embeds SRS into the binary and allows retry configuration of eth client.
