🎉 Featuring

• Fully generic UncheckedExtriniscV4 (see #418):
  • Signature, AccountId and Signer type are no longer hardcoded, but fully adaptable.
  • Introduced ExtrinsicSigner struct for easy type assignment
• submit_extrinsic (and watch) no longer requires encoded extrinsic, but the UncheckedExtrsinsicV4 itself. This way, the correct extrinsic type is enforced by the compiler. The encoded extrinsic may still be submitted with the newly introduced submit_opaque_extrinsic (and watch). See #421
• Introduced new functionality with fetch_events_for_extrinsic and fetch_events_from_block. With these functions, events associated to a specific event or inside a given block can be easily retrieved. Some examples have been adapted to show the use case of these features. See #437.
• Extrinsic creation code was heavily simplified and a trait for each implemented pallet was introduced. This allows mocking and better unit testing on the user side. See #434

🎉 Featuring

• Newly introduced rpc clients:
  • tungstenite client
  • jsonrpsee client. With this client, the issue with too many node requests has finally been solved. See #366.
• Enhanced no_std support: Everything is now no_std compatible, except for the rpc clients. See #377.
• The Api is finally abstracted behind traits, allowing easy mocking and exchanges. See #363.
• New functionalities, such as submit_and_watch_extrinsic_until_success, get_storage_keys_paged and several system-getter helpers.
