Natron 1.0 is out

This is the first stable release.

• New HSVTool node to adjust hue, saturation and brightnes, or perform color replacement.

• New HSVToRGB & RGBToHSV nodes to convert between these 2 color-spaces

• New Saturation node to modify the color saturation of an image.

• New DiskCache node. This node allows to cache a branch of the compositing tree to re-use it later on without re-computing the images. This cache is persistent on disk and is saved between 2 runs
  of Natron. You can configure the location and maximum size of the cache in the preferences of Natron; in the Cache tab.

• A new progress bar will display the progression while loading a project

• Tracker: all tracks are now multi-threaded for better performances. Also fixed a bug where the overlay displayed while tracking wasn't matching the underlying displayed image.

• Roto: Selected points can now be dragged from everywhere within the bounding box instead of only the cross-hair.

Full release changelog list is here.

• Python 3 scripting: parameter expressions, user parameters, callbacks, groups, custom graphical user interface thanks to Pyside and overall control over the application.
• Optical flow: This will be integrated with a set of different plug-ins handling motion vectors. The motion vectors will be generated with a VectorGenerator node and used within several effects such as Motion blur or Retiming. 
• G’mic integration: G’mic is a full featured image processing framework containing literally hundreds of effects. It will be proposed as a separate OpenFX plug-in not distributed with Natron due to license issues.
