0.12.3

If you aren't running Pony on Windows, you can ignore this version and stick with 0.12.2. Windows users are advised to upgrade as soon as possible if they are experiencing problems building binaries with the Pony compiler.

Prior to PR #1794, ponyc would only look for a linker from the version of Visual Studio with which it was compiled, and only looked at one registry key for install information. A recent change (44b2d56) broke support for Visual Build Tools C++ 2015.

[0.12.3] - 2017-04-01

Fixed

• Improve Visual Studio and Microsoft C++ Build Tools detection. (PR #1794)

0.12.2

Thanks to Gordon Tisher for finding the cause of our extreme busy wait problem on Windows and issuing a fix for it. We consider that a high priority issue which means, release away. Since it's only been a day since our last release, not a lot else in this one.

Windows, Debian and RedHat packages are available via Bintray. OSX via Homebrew should be coming soon.

[0.12.2] - 2017-03-30

Fixed

• Fix extreme CPU use in scheduler on Windows (PR #1785)
• Fix broken ponytest "only" filter (PR #1780)

0.12.1

This is a recommended update; 0.12.0 broke ponytest. No tests will run using 0.12.0. Upgrading to 0.12.1 immediately is advised.

[0.12.1] - 2017-03-29

Fixed

• Bug in ponytest resulted in all tests being skipped (PR #1778)

0.12.0

Pony version 0.12.0 has been released. It's available via all the usual channels. This is a recommended update as PR #1768 fixed a memory related issue that could result in nastiness.

The release also features a breaking change in the form of PR #1741 which implemented the "Array as Sequences" RFC. It changes the syntax for creating arrays from: ['a', 'b', 'c'] to: ['a'; 'b'; 'c'].

Enjoy!
