v0.53.0 (June 10, 2026)

Title: Expand Mithril sync access, introduce experimental Leios voting, and fix network supply reporting

Date: June 10, 2026

Version: v0.53.0

Hi folks! Here’s what we shipped in v0.53.0.

Expanded reuse Mithril sync outside the command line flow: Dingo now lets operators and integrators run Mithril sync from other Dingo based workflows while still tracking progress through download, import, backfill, and completion.
Introduced enable experimental Leios committee voting with stake based quorum: Dingo now supports experimental Leios committee voting that selects committee members from stake, shares votes across connected nodes, confirms quorum from verified stake, and accepts configured voting keys.

Improved speed up fresh Mithril backfills by skipping redundant input recovery: Dingo now skips repeated input recovery checks during fresh Mithril backfills, which reduces extra work while keeping the safer recovery path for resumed backfills.

Corrected report locked and circulating network supply accurately in Blockfrost responses: Dingo now reports locked and circulating supply more accurately and returns /network/eras responses without the extra era field.
Stabilized handle Leios endorser and ranking blocks correctly: Dingo now handles Leios endorser blocks and ranking blocks correctly, which keeps vote handling and merged block delivery aligned with expected network behavior.
Hardened resolve broad correctness checks across storage, Mithril, ledger, and protocol paths: Dingo now tightens error handling and validation across critical runtime paths.

Streamlined reduce publish jobs by dropping ancillary image builds: Release publishing now skips ancillary image builds that were not required for the main release flow.
Relaxed keep publish runs moving when attestations fail outside tagged releases: Release publishing now allows attestation failures on non release tag runs so routine publish work can continue.
Improved load genesis funding data correctly in the txpump test environment: The txpump test environment now loads genesis funding data from the generated genesis configuration more reliably, which keeps automated traffic generation working in the test setup.
Corrected count expired mempool transactions accurately in test coverage: Test coverage now checks expired mempool transaction counting correctly, which keeps validation aligned with reported metrics.
Strengthened guard test coverage against nil handling regressions: Test coverage now adds extra nil handling guards, which improves routine validation stability.
Documented record the published v0.52.1 release notes in release history: The release history now records the published v0.52.1 release notes as a documentation history update.

Thank you for trying!
