Summary

This is Anchor's third pre-release, focusing on cleanup in preparation for our first mainnet release. It also includes fixes and a couple of features for increased network resilience.

Please carefully read the details below if you want to migrate your existing Anchor instance to v0.3.0, as this release contains breaking changes.

As a reminder, Anchor currently must not be used on mainnet.

The full documentation is available at https://anchor.sigmaprime.io/.

We hope to gather the community's feedback. Please report issues or suggestions on GitHub. If you have any questions or feedback, the best place to reach us is the #anchor channel in the Lighthouse discord server.

💾 Database upgradability ⚠️

We updated our database schema to support database upgrades in future releases, as well as safety features to avoid database mixups and double use of a data directory.

🔑 Legacy key support dropped ⚠️

Anchor v0.1.0 used a custom key format. Anchor v0.2.0 deprecated that format and converted existing keys to the format used by Go-SSV. In this release, we fully remove support for the Anchor v0.1.0 legacy format.
