Pony Releases

There have been so many releases this week, we got one for everybody!

0.22.0 - Release Notes

We do have a new Pony release with lots and lots of goodness added and badness fixed: 0.22.0. Upgrading is highly recommended, but you might need to adapt your codebase as it contains some breaking changes. For full details check out the Release notes.

Get your ponyc package via docker, rpm, deb, homebrew, Gentoo ebuild or compile from source. Detailed installation instructions can be found in the ponyc repo README.

0.22.1 - Release Notes

We also had to release 0.22.1 only for getting a broken docker image build to work. Thus there is no ponylang/ponyc:0.22.0 docker image, but one tagged as ponylang/ponyc:0.22.1.

If you are using Pony 0.22.0, there is no need to upgrade.

0.22.2 - Release Notes

And we had yet another release, this time with only one single bug fix. We used this one to validate our new release process. Upgrading is nonetheless recommended.

That has been quite a busy week, especially for Sean T. Allen. Big thanks for doing all the work to get these releases out, we all been waiting for!

Items of Note

• Andrew Turley has been so kind to put together an incredibly useful Pony Cheat Sheet, especially for learning Pony.

• Version 0.1.2 of Pony Stable has been released. It is a bug fix release that fixes a bug that could cause issues if you were using a dependency whose commit was on a non-main branch. Upgrading is recommended. Release Notes.
