It features an intuitive and innovative user interface with support for layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. An active and growing online community provides friendly help, tutorials, and plugins.

Changelog:

* Refreshed user interface with new icons and visual styling. For Windows 7 and Vista, it is enhanced for Aero and "glass".
* Now uses and requires .NET 3.5 SP1, which has many built-in performance improvements.
* New effect: Blurs -> Surface Blur, by Ed Harvey
* New effect: Distort -> Dents, by Ed Harvey
* New effect: Distort -> Crystalize, by Ed Harvey
* Effect dialog responsiveness has been greatly improved.
* Images open much faster, especially on single CPU systems.
* Selection outline is no longer animated. Instead of "dancing ants", an antialiased and stippled "XOR" outline is drawn.
* Startup performance on most systems will be better by about 20%.
* Memory usage has been greatly reduced when more than one image is open.
* The font system for the Text tool has been completely rewritten, and problems with missing fonts and crashes should be a thing of the past.
* On Windows XP and Vista, the Text tool has improved text rendering quality (it uses GDI instead of GDI+).
* On Windows 7, the Text tool will use DirectWrite (instead of GDI) which gives even better performance and quality.
* The toolbar font list has improved usability, rendering quality, and significantly improved performance.
* The toolbar font list no longer requires an application restart to recognize newly installed fonts.
* When many fonts are installed, both memory usage and startup performance have been greatly improved.
* Installation prerequisites are now installed automatically, such as .NET Framework and Windows Installer.
* Updates can now be downloaded in the background, and installed automatically once you exit the application.
* General rendering quality has been improved when zoomed in.
* Added a "Utilities" menu. Updates, Languages, and Plugin Errors have been moved here.
* Added a "Manage Fonts" command to the Utilities menu.
* Clicking the middle mouse button on an image thumbnail will now close the image.
* Improved the Unfocus effect.
* The DirectDraw Surface (.DDS) file type now allows you to select the resampling algorithm for auto-generated mip-maps.
* A processor that supports SSE is now required (almost all CPUs purchased this decade satisfy this).
* Fixed an issue with Gaussian Blur and its treatment of alpha values.
* Fixed a crash with the "Units" selector in the toolbar.
* When zoomed in, it is now much easier to resize a very small selection.
* Now includes a Russian translation.
