@polkadot/api 3.5.1

v3.5.1

on Node.js NPM

Upgrade priority: Low. Recommended for parachain developers.

• Important The default for Substrate on the Address types are MultiAddress. It is recommended that chains add explicit definitions for Address and LookupSource in their types, instead of relying on the API-defaults. A future update will swap the API defaults to align with Substrate.
• Important Like the above changes in Substrate, the AccountInfo structure has also changed. It is recommended that chain developers explicitly add AccountInfo: 'AccountInfoWithRefCount' for the version with refCount on and AccountInfoWithProviders for the latest Substrate version. As per the above, the API defaults will be changed to align with Substrate.
