## Pony 0.21.1 and 0.21.2 released

We got lucky this Christmas and have been gifted with two new releases!

[0.21.1](https://github.com/ponylang/ponyc/releases/tag/0.21.1) brought us

* [Dynamic scheduler thread scaling based on workload](https://github.com/ponylang/ponyc/pull/2386) and
* [Support setting the binary executable name with --bin-name](https://github.com/ponylang/ponyc/pull/2430).

This release comes with improved stability and memory consumption of the runtime, so updating is recommended.

[0.21.2](https://github.com/ponylang/ponyc/releases/tag/0.21.2) is a bug fix release for Dynamic Thread Scheduling, and thus it deserves our gratefulness even more.

## Items of note

* Due to the holidays there has been no Pony Development Sync this week. The next one is scheduled for Wednesday, January 3, 2017 at 03:30 PM (GMT-05:00) America/New York via zoom. We'd love to have you there.

## New RFCs

* There is a new RFC out for [Class and Actor field Docstrings](https://github.com/ponylang/rfcs/pull/115).

Interested in making a change, or keeping up with changes to Pony? Check out the [RFC repo](https://github.com/ponylang/rfcs). Contributors welcome!
