Paint.NET 3.5 Beta 2
* The menu bar was rendering incorrectly for certain themes (Windows 7 / Vista).
* Some items were not showing up in the 'Recent Items' jump list (Windows 7).
* Clicking on the canvas straight from the menu would cause the paintbrush to draw a long streak.
* Copy+Paste would sometimes miss a pixel edge on the right/bottom sides, when using Fixed Ratio / Fixed Size modes.
* Fixed a crash when moving pixels off-canvas, switching tools, then trying to move the pixels back onto the canvas.
* Fixed some messed up rendering for IndirectUI effect dialogs (Windows XP).
* Performance is improved when switching between images that have lots of layers.
* Aero 'snap' wasn't working when dragging part of the glassy area of the toolbar (Windows 7).
* Added a new menu item, Window -> Glass Dialog Buttons. You can use this to disable the "glass footers" for dialogs (Windows 7 / Vista).
* Glass Dialog Buttons are now disabled when font smoothing is disabled.
* If an e-mail program isn't installed, the error message for Help->Send Feedback is more informative.
* "Centimeters" was being truncated in the toolbar.
* The shape tools were not using pixel snapping.
* Layer names with ampersands were not showing up correctly.
* Updated the internal list of incompatible and unstable plugins, which are then blocked from loading.
* Fixed a crash with the Rectangle Select tool if "Fixed Size" mode was used and negative numbers were entered.
* Fixed an access violation due to a race condition in finalizing effect rendering versus un-write protecting the layer's pixels.
* Fixed an access violation in the renderer for the background transparency "checkers".
* Fixed a crash when you would resize a selection to 0-width and/or 0-height, then expand it.
* Fixed a crash due to an overflow that prevented very large images from working (64-bit only).
* Fixed a crash with scanning/printing.
* Fixed the status bar's progress bar showing up and doing nothing for codecs that don't report saving progress, such as JPEG.
* Fixed a major issue with the readability of the "update is available" dialog in any non-English language.
* Fixed a crash with the Zoom tool.
* Fixed some really weird scroll-flickering with the Text tool.
Paint.NET 3.5 Beta 1
* Refreshed user interface with new icons and visual styling. On 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.
