ethers/v5.0.6 (2020-07-13 09:34)
ethers/v5.0.6 (2020-07-14 02:32)
--------------------------------
- Added initial throttling support. ([#139](https://github.com/ethers-io/ethers.js/issues/139), [#904](https://github.com/ethers-io/ethers.js/issues/904), [#926](https://github.com/ethers-io/ethers.js/issues/926); [88c7eae](https://github.com/ethers-io/ethers.js/commit/88c7eaed061ae9a6798733a97e4e87011d36b8e7))
- Use status code 1000 on WebSocket hangup for compatibility. ([588f64c](https://github.com/ethers-io/ethers.js/commit/588f64c760ee49bfb5109bfbaafb4beafe41c52a))
- Updated WebSocketProvider to use web-style event listener API. ([57fd6f0](https://github.com/ethers-io/ethers.js/commit/57fd6f06047a1a2a3a46fe8b23ff585293a40062))
- Normalize formatUnits to simplified decimals. ([79b1da1](https://github.com/ethers-io/ethers.js/commit/79b1da130be50df80c7e5aeb221edc5669fc211e))
