v0.23.0

• Replaced Subtree internal storage with bitmask layout (#784).
• [BREAKING] PartialMmr::open() now returns Option<MmrProof> instead of Option<MmrPath> (#787).
• [BREAKING] Refactored BLAKE3 to use Digest<N> struct, added Digest192 type alias (#811).
• [BREAKING] Added validation to PartialMmr::from_parts() and Deserializable implementation, added from_parts_unchecked() for performance-critical code (#812).
• [BREAKING] Removed hashbrown dependency and hashmaps feature; Map/Set type aliases are now tied to the std feature (#813).
• [BREAKING] Renamed NodeIndex::value() to NodeIndex::position(), NodeIndex::is_value_odd() to NodeIndex::is_position_odd(), and LeafIndex::value() to LeafIndex::position() (#814).
• Fixed LargeSmtForest::truncate to remove emptied lineages from non_empty_histories (#818).
• [BREAKING] Fixed OOMs in Merkle/SMT deserialization (#820).
• Fixed SmtForest to remove nodes with zero reference count from store (#821).
• Cross-checked RPO test vectors against the Python reference implementation after state layout change (#822).
• Fixed tuple min_serialized_size() to exclude alignment padding, fixing BudgetedReader rejecting valid data (#827).
• Fixed possible panic in XChaCha::decrypt_bytes_with_associated_data and harden deserialization with fuzzing across 7 new targets (#836).
• Added Signature::from_der() for ECDSA signatures over secp256k1 (#842).
• [BREAKING] Added info context field to secret box, bind IES HKDF info to a stable context string, scheme identifier, and ephemeral public key bytes. (#843).
• Use read_from_bytes_with_budget() instead of read_from_bytes for deserialization from untrusted sources, setting the budget to the actual input byte slice length. (#846).
• [BREAKING] Removed PartialEq/Eq for AEAD SecretKey in non-test builds, fix various hygiene issues in dealing with secret keys (#849).
• Added PublicKey::from_der() for ECDSA public keys over secp256k1 (#855).
• [BREAKING] Fixed NodeIndex::to_scalar_index() overflow at depth 64 by returning Result<u64, MerkleError> (#865).
• [BREAKING] Removed RpoRandomCoin and RpxRandomCoin and introduced a Poseidon2-based RandomCoin (#871).
• Hardened MerkleStore deserialization and fuzz coverage (#878).
• [BREAKING] Upgraded Plonky3 from 0.4.2 to 0.5.0 and replaced p3-miden-air, p3-miden-fri, and p3-miden-prover with the unified p3-miden-lifted-stark crate. The stark module now re-exports the Lifted STARK proving system from p3-miden.

v0.22.4

v0.19.8

• Added PublicKey::from_der() for ECDSA public keys over secp256k1 (#855).

v0.19.7

• Exposed StorageError and SubtreeUpdate as prep. to externalize the LargeSmt RocksDB backend (#850).
• Fixed SmtStore corruption issue on insertion of empty tree roots (#853).

v0.22.3

• Refactored to introduce a unified Felt type for on-chain and off-chain code (#819).
• Changed Ord for Word to use lexicographic ordering (#847).

v0.19.5

• Backported LargeSmtForest with its InMemory backend (#834).
• Fixed PartialMmr::add() not clearing track_latest flag after peak merges, which could result in incorrect tracking state (#835).

v0.22.2
