Version 0.928 alpha is now available from the download page.

Changes in this version include the following:

• fixed video import limit of about 3.5 minutes in windows
• there is now a toggle button at the lower left corner which allows you to turn off automatic refresh of video frames. There is also a refresh once button beside it. 
  Turning of automatic refresh can be useful when you have lots of tracks or slow effects and you need to rearrange the order of your tracks, or you want to adjust variables and don't need to preview the results.
  
• added a color hue changer, a saturation changer and an all-in-one hue, saturation and luma/brightness/contrast (adjust hsl) changer to the group of pixel filter effects
  
• eliminated unnecessary frame recalculations when opening projects to reduce load time
  
• still images can now be saved from the export panel.  Specify .png .jpg or .bmp after file name and the file will be saved to ~/t@b/export/date/ folder
• fixed home/next/prev/end buttons on time sliders so that they properly recalculate video frames.
  
• another interpolator has been added called Weird 1.  This is a spline-esque type but with irregularities that make things come out weird.
• an effect called Rotate Forward has been added to the bitmap filters folder.  This effect lets you rotate its parent as if it was always moving forward, no matter where you move the parent track in the display.
