v2.0.0

This release introduces support for the Alan fork to Mainnet.

Note: Alan databases are not backwards-compatible, meaning an upgraded node cannot downgrade without removing the database and syncing from scratch.

Warning

Mainnet operators MUST upgrade to v2.0.0 prior to the fork epoch!

Introducing Alan

Alan is the most significant SSV upgrade to date, poised to tackle scalability by dramatically reducing resource usage.

Alan changes the way a committee (group of operators) perform their validators's duties. Rather than performing every attestation and sync committee duty separately, a committee would perform them all together.

For more, see Meet Alan.
