Zero v19

Zero release 19, built from commit 161d97c.

Changes

Fixed

• zebra: invalidateblock no longer aborts the node when built with the
  progress-bar feature (all shipped images): the chain-metrics code expected
  a fork length that is legitimately absent after a rewind. Found by the qa
  reorg scenario; still unfixed upstream as of zebra v6.2.0. (161d97c)

CI

• GHCR images build on a 16-vCPU runner. (caeb8ef)

Zero v18

Zero release 18, built from commit a4e25d2.

Changes

Fixed

• zaino/zallet: the chain-index loop survives initial validator sync instead
  of exiting while zebra is still working through checkpoints. (41d4342)

CI

• z3-smoke probes run on GitHub-hosted runners and fail fast when a stack
  container is crash-looping. (a4e25d2, 41cb5ba)

Zero v17

Zero release 17, built from commit 07c2b32.

Changes

Security

• zebra subtree bumped 6.0.0 to 6.1.0, picking up four upstream advisories:
  block-template size reservation, quadratic transparent-value validation,
  sync stalling from rejected block bodies, and misbehavior scoring for peers
  pushing consensus-invalid transactions. (fe5ba7c)

Fixed

• zallet: a reorg landing between the scan cursor and stored-ahead block rows
  no longer crash-loops the wallet with a fatal BlockConflict; the wallet
  now rewinds and rescans. (c1e9f3a)
• zaino: the chain-index sync loop tolerates a syncing validator instead of
  exiting after ~45s of MissingBlockError. (1c1c302)
• zallet: fork-pinned zaino with the syncing-validator patience backport.
  (d80dd32)

Performance

• zallet: spend-search history ingestion is batched. (1f66886)

Deploy

• Shutdown grace periods raised across both bundles (zcashd 5m, zebra /
  zaino / zallet 2m; systemd TimeoutStopSec=300), and zebra's
  1-connection-per-IP Docker pitfall documented. (7e80df2)

Testing

• qa/regtest-harness: new reorg regression scenario (live-node
  invalidateblock + generate under a running wallet, restart variant),
  plus golden-chain snapshots, release-binary runs, and parallel scenario
  groups. (2d74600, d05b22e, 0a74cf3)

Docs

• zebra SECURITY.md: Zero/zebra vulnerabilities are disclosed to the Zakura
  project. (a9140af, 3ea2eb7)
