Release Notes

polkadot-js/api (@​polkadot/api)

v16.0.1

Compare Source

Breaking Changes:

• With the upgrade to Metadata v16, several fields have been removed or replaced. The following fields no longer exist in the updated metadata definitions:
  • type: This field has been completely removed in Metadata.
  • version: Previously part of ExtrinsicMetadata. Replaced by versions, which now holds an array Vec<u8> of supported extrinsic versions instead of a single value.
  • extraType: This field has been completely removed in ExtrinsicMetadata.
  • signedExtensions: Previously part of ExtrinsicMetadata. Replaced by transactionExtensions, which provides a more structured definition of extensions, and transactionExtensionsByVersion, mapping versions to active extensions.

• Metadata v16 (#​6130)
• Add dryRunApi v2 definition (#​6144)

Breaking Changes:

• Allow external signers to modify the payload (#​6030) (Thanks to https://github.com/Tbaut)

v14.0.1

Compare Source

Changes:

• TransactionExtension, ExtrinsicV5
  • This is a very large feature that gives support for Extrinsic V5. This is not a breaking change, but because of the impact it has it is a Major bump.
  • This PR acts as a forward compatible feature that still focuses on v4, but allows for the use of v5 when:
    a: The metadata extrinsic version is set to 5
    b: The extrinsic version is set to 5 when manually constructing transactions.
  • The PR allows the decoding of all v4, and v5 extrinsics including {bare, signed, general} transactions.
• Address parsing issues for H160 accounts in api.derive.accounts.{*} (#​5991)

v13.2.1

Compare Source

Changes:

• Generate Runtime Apis Dynamically (#​5986)

v13.0.1

Compare Source

Breaking Changes:

• Change assetId type in SignerPayloadJSON to HexString (#​5967)
• Keep assetId hex as an Option for toPayload (#​5968)

NOTE: This is part of the current change to generalize the SignerPayloadJSON in order to simplify its integration across other tools. The return value of assetId field with toPayload will always be its true type now, which in this case is Option<TAssetConversion> where TAssetConversion is equal to MultiLocation | AssetId.

Changes:

• Bump dev and typescript (#​5964)
• Bump yarn to 4.1.1 (#​5978)
