New Features

Audio Gain/Volume
Blur
Brightness
Opacity

Other changes:

Added Preset and simple and advanced keyframes to the Balance and Pan audio filters.
Added a Levels video filter with simple and advanced keyframes!
Added Properties > Color Range for video clips.

Replace the Mask video filter with 3 new filters:

Mask: Simple Shape
Mask: From File
Mask: Apply

The new Mask: Apply filter makes it possible to mask filters without using multiple tracks! Use Mask: Simple Shape or Mask: From File to start the filter mask followed the video filters to be masked followed by Mask: Apply to apply the mask to the filters in between. Filters before or after the mask filters affect the entire video frame. One can still use Mask: Simple Shape or Mask: From File to affect the alpha channel for multitrack compositing as before. This makes them compatible with existing information and tutorials that suggest using multiple tracks as well as enabling collage/montage or transition effects when the tracks do not use the same clip.

The new Mask: From File is a powerful new video filter offering 3 modes:

wipe transition (stock or custom)
Channel > Brightness from a video or image file (File > Custom...)
Channel > Alpha from a video or image file. Moreover, Threshold can be animated with simple or keyframes, which is especially nice when used with luma-wipe image files (stock or custom). Not only can you wipe on a masked filter but also you can use this as an alternative way to make a wipe transition using multiple tracks (instead of same track transition).
