Synfig Studio 1.3.9 Development Build Release

Dear Community,

only a few days after the previous release, the Development Build 1.3.9 of Synfig Studio is out :slight_smile:
Full announcement and details/Bugfixes

As always, I would recommend to use this version to benefit of major improvements since the release of last stable version (1.2.1)

Enjoy :slight_smile:
