Midnight Indexer 4.3.3-rc.4 Release Notes

Release date: 2026-06-01

Release type: Pre-release (development line)

Git tag: v4.3.3-rc.4

Tree hash: 18fa059cf3bb1df49b7d49c20f0af4193c399cb4

Environment: All public networks (mainnet, preprod, preview, devnet, qanet)

Note: this release candidate pairs with node 1.0.0 and ledger 8.1.0 and is the fast-follow patch on the Midnight 1.1 indexer line. Refer to MNF advisories for current deployment recommendations.

Summary

Release candidate on top of 4.3.3-rc.3. Adds a lazy transaction reference field to the dust and shielded nullifier transaction subscriptions (#1208), so consumers can navigate from a nullifier match to the full transaction without a separate lookup query. The field is @ beta. This is the only change since rc.3.

Dependencies

• Node: 1.0.0 (supports 0.22.x as well)
• Ledger: 8.1.0
• Bundle tracking issue: Midnight Release 1.1

No dependency changes in this release candidate; the only change since rc.3 is #1208. Node 1.0.0 and ledger 8.1.0 are the paired versions carried by the 4.3.3 line (set in rc.3 and rc.2 respectively).

Add transaction reference to nullifier event types	New feature (@ beta)	#1208

New Features

Transaction reference on nullifier event types (#1208)

Adds a transaction: Transaction! field (@beta) to DustNullifierTransaction and ShieldedNullifierTransaction. It is resolved lazily via the existing transaction DataLoader, so it is fetched only when the field is selected, with no payload cost for consumers that don't request it. This lets wallet sync pull the full transaction inline from a nullifier match instead of gathering hashes and querying separately. Both source tables (dust_nullifiers, zswap_nullifiers) have transaction_id NOT NULL, so the field is non-null. transactionId and transactionHash are retained as the resumption cursor and sequencing key.

Breaking Changes or Required Actions

None for stable API consumers. The transaction field added in #1208 is additive and @beta (no stability guarantee), so existing queries are unaffected.
