• [breaking] paysFee on system.ExtrinsicSuccess/system.ExtrinsicFailed events can now be a string "Yes" or "No" on newer runtimes.
• To provide a stable API, all extrinsics now have a paysFee field directly on them that is guaranteed to be null (if no success or failed event is present) or a boolean.
• Added onInitialize and onFinalize events to the block view (#40, #44)
• Fixes the transaction fee amount (#41).
• Bumped @polkadot/api to 1.14.0-beta.20.
