Liquib 2.1 was developed with a new compiler and converted to a different GUI system.  A Bloom Tool and a Cloud Effect have been added.  A new Sequons feature has been introduced, along with many other enhancements.  Read on for further details:  (Also see Liquib 2.1.1 and Liquib 2.1.2)

• Re-engineered Code =>  The Liquib program code has been converted to utilize the excellent Ultimate++ (U++) application development framework.  U++ is a versatile set of open-source libraries and tools (BSD license), created by an international team of brilliant developers.  Further information and download links are available at http://www.ultimatepp.org/.  Liquib has also been built with a different compiler, which should provide somewhat improved performance.

• Bloom Tool =>  The new Bloom Tool radiates petals from the point where the mouse is clicked, and then duplicates them based upon mouse movements. 
  
  As the mouse is dragged downward or upward, petals are created outward or inward respectively.  Dragging the mouse right or left rotates generated petals clockwise or counter-clockwise.  Diagonal motion will combine those two actions.  The petals can be composed of varying colors or they can be cloned from the original source image.  The size, shape, number and spacing of petals can be specified.  The resulting Blooms don't much resemble real flowers, but they can be quite interesting.
  

• Cloud Effect =>  The Cloud Effect produces vaporous objects that can drift and swirl as if buffeted by wind currents. 
  
  When colors and other parameters are set appropriately, their appearance can be much like naturally occuring clouds.  However, it is also quite possible to create objects that would never be seen in the skies above planet Earth, perhaps instead resembling cotton candy clumps, poisonous fumes or the colorful gaseous nebulae of exploded supernovas.  Each mouse click produces a single Cloud, while clicking and dragging the mouse creates a trail of smaller Wisps.  Clouds can be specified as Cumulus or Stratus, and further refined with Puffiness and Density parameters.  The evolving action of Clouds and Wisps is controlled by the Turbulence, which causes rotational perturbations, and the Drift, which produces lateral shifts
  

• Sequons =>  A Sequon performs a sequence of actions for a particular Tool or Effect.  While the general operation of each Sequon is pre-determined, there is also typically an element of randomness, partly dependent on how parameters are currently set.  In many cases, a Sequon sequence would be quite difficult, extremely tedious or even impossible to apply manually.  A button can be clicked to initiate the current default Sequon.  Right-click to show a menu of currently available Sequons and options.  Sequons can be included with Automatic Effects, along with Random Effects and Scripted Sequences.  During Automatic Effects, Sequons are chosen randomly, using randomly selected Sequon Options.

• Reflect Beyond Image Edges =>  Many of the Liquib Tools and Effects shift image pixels to different positions, so when a Tool/Effect is applied near the image edges, the program often might calculate that it needs to transfer pixels from outside of the image.  In such cases, prior versions of Liquib would typically use the currently configured Background Color to represent those pixels that were shifted into the picture from beyond the image boundaries.  With Liquib 2.1, a new Reflect Beyond Image Edges option has been added to the Tool/Effect Options screens for those Tools and Effects.  When Reflect Beyond Image Edges is set, the program will treat the images edges as if they were 'mirrors', and will normally pull pixels from within the image, rather than use the Background Color.  The operation of this option also depends on the current setting of the Confine Effects To Image Area option (under the View Menu), so it might help to experiment with different combinations of those two settings to get a better feel for how they work together.

• Other =>  Many other improvements have been made with Liquib 2.1.  Here are a few that should be mentioned:
  • A new option labeled Copy and Paste into New Pool has been added to the Pools and Edit Menus.  This option will Copy the current screen image, create a new Pool and Paste the copied image into that Pool.  The pasted image will then serve as the source image for the new Pool.
  • Liquib can now properly handle files and directories with names encoded in alternate character sets (such as Cyrillic, Chinese, etc.)
  • Liquib Effects typically consist of any number of Actions that are initiated by mouse clicks and movements, and those Actions can then continue to evolve by Steps until the Effect is stopped (when Keep is pressed perhaps).  With manually applied Effects, no more that one Action can be started at each Step.  It's now possible, after an Effect has been completed, to alter the Step at which each individual Action begins by using the Adjust function or the Image Manipulation History screen.  For example, several Drops might be adjusted so that they occur at the same Step, creating the appearance of them bursting into existence all at once.  (Several of the pre-defined Sequons use this technique.)  The Script Editing screen can also be used to make similar changes to Effect Actions that have been captured in Scripts.

Liquib 2.1.1 was primarily released to fix crashes that would occasionally occur with certain Tools when the left mouse button was released outside of the window.  A few other minor tweaks were made.  The free Liquib Screensaver has also been updated to version 2.1.1.

Liquib 2.1.2 

Version 2.1.2 of Liquib corrects the positioning of certain Effect Sequons.  This fix was also applied to the Liquib Screensaver.
