## Pony 0.19.0 Released

Yesterday Pony 0.19.0 was released. The release contains breaking changes. If you don't use the `Itertools` package then upgrading should be painless. If you do use `Itertools`, the process should be relatively straightforward. MacOS, FreeBSD and Dragonfly BSD users are recommended to upgrade as soon as possible to fix a race condition on the kqueue event system. More details information is available in the [release notes](https://github.com/ponylang/ponyc/releases/tag/0.19.0).

## Items of note

- The ["Improve `Iterools` API" RFC](https://github.com/ponylang/rfcs/blob/main/text/0049-improved-itertools-api.md) has been implemented and released. See the [Pony 0.19.0 release notes](https://github.com/ponylang/ponyc/releases/tag/0.19.0) for how to update for the breaking API change.
- Audio from the [August 30, 2017, Pony development sync](https://vimeo.com/915150542) is available for your listening pleasure.
- Andrew Turley has started a [project](https://github.com/aturley/pony-lldb) that collects together helpful commands for usage with Pony and LLDB. Check it out and contribute today!
