@polkadot/api 2.4.1

v2.4.1

on Node.js NPM

Upgrade priority: Low. No breaking changes, however it does move api-contract forward with additional features.

Contributed:

• Add support for both {i,u}256 types on contracts (Thanks to https://github.com/seanyoung)

Changes:

• Add .keysAt & .entriesAt to query maps at a specific blockHash
• Adjust ordering of type injection, any types: { ... } definitions not have precedence
• Correctly format Tuples in both RPC and const definitions as part of type generation
• Add node-template to known types (tracking inside API), remove warnings for the spec
• Add initial implementation for new Substrate MultiAddress type
• Add api.derive.chain.subscribeNewBlocks for full block retrievals
• Contracts identifiers to .{exec, read}('name', ...) now matches on both snake_case and camelCase (consistency)
• Cleanup contracts serialization for messages to allow both to and from
• Add deserialization of contract events against the ABI
• Adjust contracts metadata parsing to be future-proof with type retrievals
• Add tests for Solang into contracts, re-organize layout per type
