Version 2.12.3

This is a bug-fix release which corrects two problems with 2.12.2:

• Fix crash when changing DCP audio channel count in some circumstances.
• Fix failure to check for updated DCP-o-matic versions (always reporting that the server is unavailable).

It also contains an updated fr_FR translation from Thierry Journet. Thanks Thierry!

Version 2.12.2

The most significant changes in this release are:

• DCP player — a separate and functional (albeit slow) player for DCPs.
• Audio in the preview — check your content's audio from inside DCP-o-matic.
• Export to ProRes/H.264 — allow people to preview your project, or convert DCPs to other formats.

There are also the usual set of translation updates, bug fixes and assorted new small features. Here's a full list:
