0.18.0

Breaking Changes

• [BREAKING][param][rust] Moved the account ID into GetAccountRequest::new(account_id). NodeRpcClient::get_account takes only the request. Removed Default from GetAccountRequest (#2756).
• [BREAKING][type][rust] Added AccountFetch with builder methods for storage and vault policies. GetAccountRequest::with_fetch replaces its storage and vault fields and builder methods. ForeignAccount::Public and ForeignAccount::public take AccountFetch, and ForeignAccount::fetch replaces storage_slot_requirements. Public foreign account declarations use a new binary encoding. AccountDetails::into_domain takes the shared AccountFetch. Both policies default to Skip: a public foreign account no longer fetches its vault with the inputs, and execution reads each asset through a per-asset lookup instead. Set VaultFetch::Always or VaultFetch::Assets to keep the previous behavior (#2756).
• [BREAKING][removal][rust] Removed the unused TransactionRequestError::ForeignAccountDataMissing, MerkleError, and StorageMapError variants. Missing account details return RpcError::ExpectedDataMissing, and invalid account data returns RpcError::InvalidResponse (#2756).
• [BREAKING][arch][rust] Updated protocol dependencies to 0.18, Miden VM to 0.36, miden-debug to 0.19 and miden-node-proto-build to 0.18.1. The client uses the node 0.18 RPC and note transport APIs and requires a node 0.18 (#2732).
• [BREAKING][type][rust] Added the GetAccountError::StorageSlotNotFound and GetAccountError::StorageSlotNotMap variants for the node 0.18 GetAccount error codes 6 and 7. These codes previously parsed as GetAccountError::Unknown (#2732).
• [BREAKING][behavior][rust] Note transport stores one cursor and the tags that it covers under NOTE_TRANSPORT_SYNC_STATE_KEY. A fetch reads all tags up to the sync_to bound that the service returns for the first request, and saves the bound when all covered tags reach it. Added tags start from the first retained note, so adding or removing a tag no longer delivers notes again to the other tags. The client migrates the per-tag cursors under the deprecated NOTE_TRANSPORT_CURSORS_KEY to their lowest cursor (#2742).
• [BREAKING][param][rust] NoteTransportClient::fetch_notes_page and GrpcNoteTransportClient::fetch_notes_page take an optional cursor and a sync_to bound, and the trait method has no default implementation. NoteTransportPage has a sync_to field with the bound that the service used (#2742).
• [BREAKING][type][rust] NoteTransportCursor has public nonce and sequence fields. Removed NoteTransportCursor::init, from_parts, and parts. Use None where the initial cursor was used. Store::get_note_transport_cursor returns Option<NoteTransportCursor>, and MockNoteTransportNode::get_notes takes an optional cursor (#2742).
• [BREAKING][removal][rust] Removed NoteTransportClient::fetch_notes, GrpcNoteTransportClient::fetch_notes, and MockNoteTransportApi::fetch_notes. Use fetch_notes_page (#2742).
• [BREAKING][type][rust] Added the VaultFetch::Assets variant, which requests proofs for specific vault assets from the node 0.18 GetAccount endpoint. AccountVaultDetails is an enum with the TooManyAssets, Assets, and Partial variants, which replace the too_many_assets and assets fields. The Partial variant holds the proofs for a VaultFetch::Assets request. The is_too_many_assets, assets, and into_partial_vault methods read the variants. The conversion from the gRPC type rejects a response that sets more than one of these fields. The gRPC conversion AccountDetails::into_domain takes the vault request as a new parameter, to check that the proofs cover the requested assets (#2744).
• [BREAKING][type][rust] Added the RpcLimits::vault_assets_limit field, which holds the maximum number of assets in a VaultFetch::Assets request. The client reads it from the node GetAccount limits. The client cannot read the RPC limits that an earlier client version stored, so a store from an earlier version does not load (#2744).

Features

• [FEATURE][rust] A public foreign account that the client tracks gets its transaction inputs from the store at the sync height. Only the witness is fetched from the node when Client::track_account_witness did not cache one (#2756).
• [FEATURE][rust] Added TryFrom<AccountDetails> for PartialAccount and AccountProof::into_account_inputs. Both keep the available vault and storage proofs and reject entries, assets, and proofs that do not match the account header (#2756).

Fixes

• [FIX][rust] Preserved the genesis commitment in RPC headers when it is set during a native connection handshake (#2748).
