Validator migration required. Run miden-validator migrate.

Breaking Changes

• Funding Service: Remove --deposit-scan-interval and MIDEN_FUNDING_DEPOSIT_SCAN_INTERVAL; deposit discovery now follows --poll-interval. (#2793)

Changes by Scope

General

• Added: Make gRPC decoding limits configurable across components, keeping the 4 MiB default. (#2791)
• Fixed: Update TLS stores to address eMudhra CA compromise (#2803)
• Fixed: Updated OpenTelemetry dependencies to address a baggage parsing denial-of-service vulnerability. (#2805)

RPC

• Added: Support bounded selective vault queries through GetAccount. (#2799)
• Changed: SyncNotes reports block_to in pagination_info.block_num when no matching notes remain. (#2737)
• Fixed: Reject expired transactions and transactions with locally committed input nullifiers before forwarding from full nodes. (#2750)
• Fixed: SyncAccountVault and SyncAccountStorageMaps return OUT_OF_RANGE when one block exceeds the page limit, instead of skipping it. (#2737)
• Fixed: Skip invalid accept media ranges instead of immediately returning an error, so that subsequent ranges are considered (#2677)
• Fixed: Fixed account vault and storage map syncs silently returning incomplete data for block ranges ending outside the history retention window. (#2676)
• Fixed: Fixed GetAccount returning an internal error instead of INVALID_ARGUMENT when a storage map request names a missing slot or a value slot. (#2679)

NTX Builder

Validator

• Added: Added validator-backed recovery of block proving inputs and optional offline proving to support sequencer failover. (#2786)
• Added: Add configurable proving input retention, defaulting to the latest 10,000 signed blocks. (#2794)

Note Transport

• Added: Added fixed-range note fetching so clients can synchronize tag chunks using one shared cursor. (#2785)

Network Monitor

• Fixed: Load partial USDCx faucet state and validate funding notes against the requested recipient and amount. (#2793)

Funding Service

• Breaking: Remove --deposit-scan-interval and MIDEN_FUNDING_DEPOSIT_SCAN_INTERVAL; deposit discovery now follows --poll-interval. (#2793)
• Changed: Apply wallet and deposit updates atomically, retry transient synchronization failures, and report status from the worker's latest completed sync. (#2793)
• Fixed: Load partial USDCx faucet state and fetch only storage proofs required for funding transactions. (#2793)

Docs

• Added: Document the historical account state retention window and the resulting GetAccount error (#2618)
