v0.46.3 (May 17, 2026)

Title: Stronger ChainSync recovery, faster database queries, and broader rollback test coverage

Date: May 17, 2026

Version: v0.46.3

Hi folks! Here’s what we shipped in v0.46.3.

Highlighted no brand new end user features: This patch release focuses on reliability, performance, testing coverage, and release note upkeep.

Expanded rollback coverage with ouroboros-mock v0.11.0: The ouroboros-mock v0.11.0 update broadens synthetic rollback conformance coverage, which gives operators stronger confidence when nodes need to roll back.
Accelerated governance lookups across account and UTxO data: New database indexes help governance related reads return more quickly when workflows depend on account and UTxO information.
Streamlined stake by pool lookups on account data: A new database index helps pool focused account reads respond more quickly.
Documented the previous patch release more clearly: The repository now includes v0.46.2 release notes, which makes recent upgrade history easier to review.

Restored safer post plateau peer recovery: Node recovery now starts on a fresh connection after peers fall out of alignment, which makes recovery safer after plateau events.
Updated clearer runtime metrics guidance: The runtime metrics note now explains the mapping directly, which removes an outdated local file reference.

Clarified safer recovery after plateau events: Recovery now begins on a fresh connection after peers fall out of alignment, which reduces recovery risk.
Emphasized more responsive governance and pool reads: Governance and pool oriented database reads should be more responsive because of the new indexes.
Reinforced broader rollback confidence and clearer release history: Rollback focused coverage improved in this patch release, and the documented v0.46.2 notes make recent release history easier to review.

Thank you for trying!
