Zaino 0.6.0 — Ironwood (NU6.3)

This release adds full support for the Zcash Ironwood network upgrade (NU6.3), which activates on Mainnet at block height 3,428,143 (~2026-07-28).

Highlights

• Ironwood/NU6.3 support: activation heights, v6 transaction format, database migration, Orchard-to-Ironwood pool transition (#1362, #1376, #1379, #1384)
• BlockchainSource unification: merged FetchService and StateService into a single NodeBackedIndexerService (#1361)
• Zebra v6.0.0 stable: upgraded from RC to final release — zebra-chain 11.1, zebra-state 10.1, zebra-rpc 11.1 (#1394)
• zcash_* crates stabilized: dropped pre-release pins in favor of published stable versions (#1394)
• Activation heights from validator: the validator is now the sole source of activation-height truth at runtime (#1375)
• Startup crash loop fix: zainod no longer loops when the validator has no blocks yet (#1389)

Breaking changes

• chaintip_update_subscriber now returns Option instead of panicking
• Public Testnet renamed consistently across all APIs
• Activation heights are enforced from the validator, not hardcoded

Reliability fixes

• Service teardown made safe off the multi-thread runtime
• Tip-relative getblock heights resolved correctly
• getblockdeltas omits multi-address outputs again
• sendrawtransaction preserves typed RPC errors
• Error causes preserved across the BlockchainSource boundary
• getchaintips proxied to the validator while still syncing

Infrastructure

• Publish dry-run CI pipeline for release gating (#1359)
• Test runner with per-suite timing and --all mode (#1394)
• DRY zaino-common: logging and activation-height conversions consolidated (#1371)

Crate versions

Upgrade notes

All node operators running Zaino should upgrade before the Ironwood activation height (3,428,143). The database migration from v1.2 to v1.3 runs automatically on first startup.
