v0.92.1

• The API now correctly sets the ss58 prefix as retrieved from the chain properties via ss58Format
• Bump to @polkadot/util 1.4.1, removing use of ExtError
• The Keyring from @polkadot/keyring is now exposed on the API as well. You can do import { Keyring } from '@polkadot/api' - this alleviates the need for extra dependencies (apart from @polkadot/api), and since the keyring is critical for signing operations, aligns everything in one bundle
• Support the latest Polkadot & Substrate master branches (incl. metadata updates)
• Getting started documentation has been made available
