# 0.1.17 (September 28, 2020)
### Fixed
- Incorrect inlining of `Event::dispatch` and `Event::child_of`, which could
result in `dispatcher::get_default` being inlined at the callsite ([#994])
### Added
- `Copy` implementations for `Level` and `LevelFilter` ([#992])
Thanks to new contributors @jyn514 and @TaKO8Ki for contributing to this
release!
