Version 1.6 introduces new Rumple and Clone Tools, and a new Aura Effect.  Also, a primary emphasis of Liquib 1.6 was to improve the rendering quality of several Tools and Effects.  More details:

• Rumple Tool =>  The Rumple Tool disrupts the surface of an image, producing lumps and crevices that corrupt the scene's appearance.  The results can be fairly mild or extremely grotesque, depending on the configured Intensity and other parameters.  Rumpling can be performed in 3 styles:  Skew, Clump and Wrinkle.  Rumple Action can be either Origin to Cursor to pull and turn the disruption area about the point of the original mouse click, or Follow Path to produce a swath of destruction as the mouse is dragged across an image.  Optionally, Shading can be enabled to highlight surface distortions with lightness/darkness to emphasize depth.
  

• Clone Tool =>  The Clone Tool snatches a portion of an image where the mouse is clicked, and then replicates that cameo picture continuously as the mouse is dragged across the display.  The shape of the Cloned segment can be Circle/Oval, Rectangle, Diamond or Hexagon.  The Keep Clone in Original Orientation option will cause the Clone shape to remain at a consistent angle, determined by the initial mouse click, and the enclosed image will remain upright as it is replicated.  Otherwise, both the Clone shape and the picture will turn and re-orient as the Clones are reproduced along the path of the mouse.
  

• Aura Effect =>  The Aura Effect blends splotches of colors with the source image upon each click of the mouse.  It is particularly useful for infusing brilliant, vibrant colors into a drab picture.  The shapes can move and rotate, and the colors shift and pulse in cyclical patterns.  Clicking and dragging the mouse creates a string of smaller splotches called Halos.  The available Aura and Halo styles are Disk, Ring, Star and Burst.  The Color varieties are Rainbow, Rainbow Shift, Solarize, Solarize Mix, Gleam and Rainbow Swap.
  

• Tool Improvements =>  Stylus and Comb Tool manipulations have been refined to produce less pixelation -- still not perfect, but noticably better.  The Curl method of the Contort Tool now creates smoother results.  Spray Tool droplets are now somewhat cleaner, especially the Crater variety.  New colorized methods have been added for both the Smear and Wipe Tools, including Solarize, Gleam, Negate Red, Negate Green and Negate Blue.

• Effect Quality =>  Drop, Wave, Bubble, Flow and Quake Effects can now be rendered with two levels of Quality.  Normal Quality mode renders much quicker, and is usually appropriate while effects are evolving on the screen in real-time.  Improved Quality mode renders with greater precision and produces smoother, less ragged results.  The Options screen for each Effect provides choices for using Improved Quality in various situations (Rendering, Recreating and Upscaling).  Generally, unless you have a very fast computer or don't mind sluggish performance, it's best to use Normal Quality during the real-time Rendering process.  Then set the Render with Improved Quality when Finished option to automatically re-render scenes when the Effect is finalized (by choosing Keep or by switching to another Tool or Effect).  A Quality button is also available to toggle between Quality modes interactively, Normal = / Improved = .
