Changelog Entries Requiring Attention

• Broken PR #2577: parsing changelog entries: TOML parse error at line 3, column 10 | 3 | impact = "fix" | ^^^^^ unknown variant fix, expected one of breaking, added, changed, fixed, removed, deprecated

Breaking Changes

• General: Bumped MSRV to 1.98.1 to avoid a miscompilation bug on 1.98.0 (#2560)
• RPC: Updated to miden-protocol v0.17 and miden-crypto v0.30. (#2570)
• RPC: RPC and prover protobuf APIs now use canonical Miden object bindings and structured proof and submission messages. Clients must regenerate bindings and update request and response handling. (#2580)
• General: Persist and verify the genesis protocol configuration. Genesis files must now include the full configuration; existing deployments require a new genesis artifact and a fresh bootstrap. (#2590)
• RPC: Expose protocol configurations through gRPC and use verified configs across synchronization, recovery, NTX execution, monitoring. (#2596)
• RPC: Changed the validator’s SignBlock API to use a dedicated SignBlockRequest and removed the signing-only protocol_config field from BlockProofRequest. (#2621)
• Network Monitor: Fees are funded from the funding service via --funding-service-url; the faucet is no longer a source of fees. (#2603)

RPC

• Breaking: Updated to miden-protocol v0.17 and miden-crypto v0.30. (#2570)

• Breaking: Changed the validator’s SignBlock API to use a dedicated SignBlockRequest and removed the signing-only protocol_config field from BlockProofRequest. (#2621)
• Added: Added RegisterAccount which adds an account to the allowlist using an invitation code (#2610)
• Added: IsAccountAllowed which returns true if the given account ID can be deployed. (#2628)

Node

• Added: Added a new sequencer database for tracking account allowlist (#2608)
• Added: Added an admin REST API to the sequencer for managing the account allowlist (#2609)
• Added: Sequencer now rejects unregistered non-network accounts (#2612)
• Added: A genesis [[wallet]] entry accepts an optional name, which sets its account file name. (#2600)
• Changed: Clarify the genesis-block deserialization error to hint at a possible node-version mismatch (#2593)
• Fixed: Pre-fund the generated native faucet's own vault at genesis so its mint network transactions can pay fees. (#2526)
• Fixed: An invalid accept header no longer invalidates a later one (#2579)
• Fixed: Correctly support multiple separate Accept headers (#2578)
• Fixed: Reject prefixes in SyncNullifiers that have more than 16 bits instead of silently truncating them (#2589)

Network Monitor

• Breaking: Fees are funded from the funding service via --funding-service-url; the faucet is no longer a source of fees. (#2603)
• Added: Support fee-charging chains: the monitor funds its accounts from the faucet, attaches fee sponsorships to increment notes, and tops its balance up automatically. (#2526)

Funding Service

• Added: New service which reports its funding account and balance over a Status endpoint. (#2600)
• Added: RequestFunds sends the native asset to an account as a private pay-to-ID note and returns it once committed. (#2601)

Docs

• Added: Operator documentation for the funding service. (#2603)

Internal

• Fixed: Fixed premature eviction of account vault and storage map history when frequent updates occurred within the 50-block retention window. (#2599)
