Release Notes

palfrey/serial_test

### [`v1.0.0`](https://togithub.com/palfrey/serial_test/releases/tag/v1.0.0) [Compare Source](https://togithub.com/palfrey/serial_test/compare/v0.10.0...v1.0.0) Nothing since 0.10.0. Well, [a test dependency upgrade on `tokio`](https://togithub.com/palfrey/serial_test/pull/87), but nothing in the published library. This is mainly just as a "1.0!" release.
