## Pony 0.19.1 Released

Last Thursday, Pony 0.19.1 was released. It's a non-breaking change **and** includes a hot new feature so we think you should update soon. The highlight of 0.19.1 is definitely the implementation of [RFC #45: "Lambda and Array Inference"](https://github.com/ponylang/rfcs/blob/main/text/0045-lambda-and-array-inference.md). It's an incredibly useful feature that greatly improves Pony's programmer ergonomics. Check out the [blog post announcing the release](https://github.com/ponylang/ponyc/releases/tag/0.19.1) for full details.

## Items of note

- [Pony-stable](https://github.com/ponylang/pony-stable), the Pony dependency manager, is now available via [Homebrew](https://brew.sh/). Prebuilt binaries for Windows and Linux are [coming soon](https://github.com/ponylang/pony-stable/issues/26).
- Wallaroo Labs, formerly Sendence, released their in-progress [Pony Kafka client](https://github.com/WallarooLabs/pony-kafka). The client currently only works with their [custom ponyc fork](https://github.com/wallaroolabs/ponyc), but they announced that it should be ported to mainline ponyc "soon".
- Sean T. Allen (that's me!) announced the 0.1 release of a pure Pony [MessagePack](http://msgpack.org/index.html) client called [pony-msgpack](https://github.com/SeanTAllen/pony-msgpack/releases/tag/0.1). It's still feature incomplete but will becoming more full featured over time.
- Audio from the [September 13, 2017 Pony development sync](https://vimeo.com/915151279) is available for your listening pleasure.

## News and Blog Posts

- "A Framework for Gradual Memory Management" proposes a way for a language's compiler to allow a single program to use multiple memory management strategies optimized for performance, with compile-time safety guarantees. The Pony community might be interested because it adopts Pony's reference capabilities as part of its proposed mechanisms.
- Jorge Díaz wrote a blog post about his first experience with Pony- [Go through this concurrent world in the company of a Pony](https://medium.com/@jdia/go-through-this-concurrent-world-in-the-company-of-a-pony-f24bcf501855).
