Release Notes - v0.189.5

v0.189.5 (July 28, 2026)

Title: Update CI workflow checkout and tighten chainsync validation

Date: July 28, 2026

Version: v0.189.5

This release updates the checkout action used in CI workflows and tightens node-to-node chainsync rollforward handling for unknown eras and block types.

💪 Improvements

• Updated CI workflow checkout action: Seven workflows now use actions/checkout v7.0.1, bringing upstream fixes for unsafe pull request checks, ASCII whitespace trimming, and --unset escaping.

• Fixed node-to-node chainsync validation: Client rollforward handling now rejects unknown eras before continuing, and server rollforward handling now returns clear errors for unknown block types.

🙏 Thank You
