I just uploaded the latest AppImage candidate for the stable branch(18.04):
This AppImage includes all the latest fixes:
* Fix regression in 17.12.3 breaking fades and geometry keyframes on resize
* Fix startup crash in some configs
* Fix luma in wipe transition not found after saving project
* Stop warning about missing app for DVD
* Fix lowres icons on High DPI
* Fix download resources (render profiles, etc) sometimes broken
* As well as the latest MLT version fixing the alpha transparency of some
10bit YUV formats.
Translations are missing, I hope to get them back for the final 18.04
Please test and report problems quickly so I can maybe improve the AppImage
for the final release (19th of april).
