polkadot-js/api v3.7.1

on GitHub

Upgrade priority: Low. However recommended for current Substrate master, Polkadot and Rococo users and those wishing to support the upcoming Polkadot 28 runtime with the new MultiAddress.

• Breaking change As indicated in the 3.5.1 release notes, the Address/LookupSource defaults have now been adjusted for MultiAddress. If your chain does not use these types, explicitly add the correct Address/LookupSource types. This new extensible format is mean to cater for all address types into the future, removing a lot of discrepancies between chains.
