1.13.0 - 2026-09-22

Changed

• Strict DAG-CBOR canonical codec: DagCborCodec was rewritten for full spec parity — canonical key ordering (length-first, then bytewise), tag 42 CID links, big integers via tags 2/3, strict tag handling, and -0.0 normalization. The new strict flag (default true) makes decode reject non-canonical encodings — duplicate keys, indefinite-length items, non-shortest-form integers, and non-canonical map ordering — matching the go-ipld-cbor strict decoder. Pass strict: false to decode legacy/non-canonical data.
• DagJsonCodec updated for parity with the strict DAG-CBOR codec.

1.12.0 - 2026-09-19

Added

• CID.fromContent gained hashType and version parameters; CID.fromPrefixBytes, CID.validate, CID.computeForData, and CID.computeForDataSync are now part of the public surface. CID.toPrefixBytes synthesizes the implicit <version=0, codec=dag-pb> header for CIDv0, matching the Bitswap block-prefix format.

1.11.7 - 2026-09-18

Fixed

• MultibaseUtils now implements RFC 4648 encoding/decoding for base16, base32, and base64 variants directly. It previously delegated those bases to a big-integer base-x codec, which produced non-standard strings and could not decode standard CIDv1 strings such as bafkrei.... Base58btc still uses the base-x codec, which is correct for that base.
• CID.hashCode now hashes the multihash bytes by value instead of hashing a freshly allocated byte list by identity, restoring the ==/hashCode contract so equal CIDs work correctly in sets and as map keys.

1.11.6 - 2026-09-05

Fixed

• Fixed 64-bit integer overflow in DagCborCodec on Flutter-web (JavaScript runtime) by parsing bounds using BigInt.parse() instead of literal 64-bit integer values (-9223372036854775808 / 9223372036854775807).

1.11.5 - 2026-07-08

Added

• Initial extraction of dart_ipfs_core from the dart_ipfs umbrella package.
• Stable core primitives: CID, MultibaseUtils, Multicodec, MultihashInfo, MultihashUtils.
• Block abstractions: Block, IBlock, IBlockStore, BlockStoreResult, InMemoryBlockStore.
• Common codecs: IPLDCodec, RawCodec, DagCborCodec, DagJsonCodec.
• Cryptographic helpers: CryptoUtils, EncryptedData, Ed25519Signer, KeyPairExtensions.
• Small immutable data structures: ImmutableBytes, TypedMap.
