+# v0.7.0 (2020-07-14)
+- Refactor the `Error` enum so that it is `Send`, `Sync` and `'static`:
+ - Remove the `sync::PoisonError` from the `PoisonError` variant.
+ - Remove `Error::RandError` variant.
+
# v0.6.0 (2020-02-03)
- Add `String` value to the `Error::UnexpectedError` variant.
- Always store serial numbers as structs:
