polkadot-js/api v1.34.1

on GitHub

Upgrade priority: High. Metadata v12 is the next major version containing structural data exchange changes and will start rolling out to test and live networks in due course.

• Breaking change The Decorated (from @polkadot/metadata) class signature has changed. It now always expects a valid Metadata object to be passed-in, instead of raw data. It is recommended to create a Metadata object, set it on the registry with .setMetadata and then only create a Decorated instance. (Only affects metadata-only users of the API)

Contributed:

• Added support for POW block author extraction (Thanks to https://github.com/sorpaas)

Changes:

• Ensure Metadata retrieval does not pollute the default registry
• When passing { nonce: -1 } to signAndSend the API will use system.accountNextIndex to determine the nonce
• Ensure that upgrades override old registry types (non-specified in current)
• Support for Metadata v12 with fixed indices
• Cleanups for WebSocket class detection and creation
• Ensure that ignored map params yield an error on iterKey
• Cater for older chains in derive democracy locks (availability detection)
