High level summary​

  • Mithril integration (Treasury Funding Initiative 8: Mithril):
    • A node running on an on-disk backend can now also write a snapshot in the portable in-memory format when given an export path. Mithril signers need a single agreed format to sign, and this lets them get it straight from the node instead of running a separate conversion tool. This is the first part of #1574; the export format is not fully complete yet, as it still needs some fixes on the LSM-trees side (#2053).
    • Added a snapshot policy for Mithril that makes the timing of ledger-state snapshots predictable, using cadence values agreed with the Mithril team. Predictable snapshots let signers agree on the same state to sign (#2063).
  • Maintenance and tooling (Treasury Funding Initiative 17: Maintenance and Support):
    • db-analyser can now start an analysis from a snapshot at a chosen slot. Given --analyse-from, it picks the newest snapshot at or before that slot and replays only the blocks needed to reach it, instead of always replaying from genesis (#2061).
    • Fixed a rare corner case where a snapshot taken at the same slot as the immutable database tip, on an epoch boundary block, triggered an error. The node now discards the snapshot in that situation (#2070).
  • Documentation (Treasury Funding Initiative 17: Maintenance and Support):
    • Full-text search is now available on the consensus documentation website. The search index is built into the site as static files, so it needs no external service (#2059).
