Paint.NET 4.0.1
更新細節：
* Changes:
- Move Selected Pixels tool performance has been significantly optimized.
- Move Selected Pixels tool was always leaving transparent black behind instead of the secondary color with alpha removed.
- Brush tools with odd-sized brushes and no antialiasing were drawing at 1 size smaller.
- Fixed some apparent ‘lag’ in the brush tools due to an off-by-1 glitch in the stroke path calculation code.
- The brush tool preview circle no longer scales by the system DPI setting, which made it too big.
- Removed the momentary hourglass/wait cursor after drawing (e.g. pencil and brush tools).
- Optimized performance of the Shapes tool, especially for the Ellipse shape.
- Paint Bucket tool will now correctly treat the selection as a boundary contour.
- Zoom tool no longer crashes sometimes when pressing the right mouse button while already holding the left mouse button.
- The status bar now reports the correct selection location when it’s outside the image boundaries (e.g. negative values).
- Auto-scrolling on the edge of the window now works correctly and doesn’t require you to "jiggle the mouse" for each scroll update.
- Touch screens no longer scroll when swiping up/down with one finger.
- Improved the pixel grid’s contrast so it’s not overwhelmingly bright.
- The transparency "checkerboard" is now aligned to the top-left of the image, instead of the top-left of the canvas.
- The cursor position reported in the status bar was off-by-1 when the value was supposed to be negative.
- Some controls (e.g. units selection in the Image->Resize dialog) were not drawing focus rectangles when using the keyboard.
- Fixed a crash (OutOfMemoryException) when using a selection tool when hardware acceleration is disabled.
- Fixed a crash (TimeBeforeLastUpdateException) in the installer. This usually happens when running in a virtual machine, and only affects animations.
- Fixed a crash (BadImageFormatException) at startup. This indicates an installation error, and will be automatically repaired.
- Fixed various crashes caused by having the wrong (old) version of PaintDotNet.SystemLayer.Native.dll. This indicates an installation error, and will be automatically repaired.
- Improved performance when software rendering is used (e.g. when hardware accelerated rendering is disabled).
- All 7th generation Intel GPUs now default to hardware rendering. All older Intel GPUs default to software rendering.
- Fixed graphical artifacts (blackness, flickering, mouse trails) on certain GPUs (e.g. NVIDIA Optimus).
- NVIDIA ION graphics cards now default to software rendering due to crashes.
- Fixed an issue that was causing beta updates to be offered even if “Also check for pre-release (beta) versions of paint.net” was disabled in Settings

更新細節：
* Performance
- A brand new, asynchronous, fully multithreaded rendering engine allows performance to scale very well with respect to the number of CPU cores whether you have 2, 4, 6, or even 16 of them.
- The responsiveness of the user interface has been greatly improved, especially when working with large images.
- Memory usage is lower.
- Improved battery life impact due to fixing the way the floating windows manage their transparency.
- Startup performance when many plugins are installed is improved
* Selections
- Selections are now antialiased, which greatly improves the quality around the edges of selected content. You can turn this on and off at any time from the toolbar.
- Everything related to selections now has much higher performance and greatly reduced CPU usage, especially if hardware acceleration (GPU) is enabled.
- The selection outline is now rendered using the “dancing ants” animation, which greatly improves the contrast between it and the image itself.
* General
- The functionality previously provided by the Utilities, Window, and Help menus has been simplified, consolidated, and moved to the top-right corner of the main window.
- The image thumbnail list has been moved up 1 row so that it no longer intrudes into the current Tool’s toolbar space. This means it will no longer “jump around” when you switch between tools. This also means that it is aligned to the top of the monitor when the main window is maximized, making it easier to click on images (Fitt’s law).
- The image thumbnail list can now be reordered with drag-and-drop.
- A brand new Settings dialog makes it much easier to configure all the tool and toolbar defaults, among other things.
- The zoom slider and units selector have been moved from the toolbar to the bottom right corner of the window (into the status bar).
- Each image now shows up as its own taskbar item. This can be disabled in the Settings dialog with “Show image previews in the Windows taskbar.”
- Layers can now be reordered with drag-and-drop.
- Ctrl+Click on the Move Layer Up/Down buttons will now move a layer to the top/bottom, respectively.
- Improved quality of Image->Resize.
- Edit –> Copy Merged will copy all layers to the clipboard without having to use Image->Flatten first.
- Copying to the clipboard now includes the “PNG” format, which allows transparency to survive from many popular applications (e.g. Office)
- You can now use the middle mouse button to scroll/pan the image at any time (same functionality as holding down the spacebar along with clicking and dragging the mouse).
- Shift+Backspace will now fill the selection with the secondary color (Backspace, the shortcut key for Edit -> Fill Selection, still fills with primary color as usual).
- paint.net now shows up in Windows’ “Default Programs” control panel so you can configure its file type associations without reinstalling.
- EXIF rotation metadata is now applied when opening images (e.g. JPG taken with a rotated camera).
- Eleven (11) new languages, bringing the total to 21: Chinese (Simplified), Chinese (Traditional), Czech, Danish, Dutch, English,Finnish, French, German, Hindi, Hungarian, Italian, Japanese, Korean,Lithuanian, Persian, Polish, Portuguese (Brazilian), Portuguese (Portugal), Russian, and Spanish.
- Crash logs are now stored in%LOCALAPPDATA%paint.netCrashLogs (e.g. C:UsersusernameAppDataLocalpaint.netCrashLogs) instead of on the desktop.
* Effects
- New effect: Photo -> Vignette.
- Improved the quality of the Photo -> Red Eye Removal effect.
- Improved UI for Layers -> Rotate/Zoom.
- Effect plugins now show up with a jigsaw puzzle icon next to them in the menus. You can hover over the effect to see information about it, including the author and location of its DLL.
- Errors while loading effect plugins are now displayed in the Settings dialog.
* Tools
- Most Tools now support “fine-grained history.” You may adjust the properties of what you’ve drawn (e.g. colors, toolbar settings) before committing to the layer (use the “Finish” button or press Enter), and each change is tracked in the history.
- Tools may now draw directly with a blending mode, configurable from the toolbar. All of the layer blending modes are supported, as well as “Overwrite.”
- Drawing tools (Pencil, Paintbrush, Eraser, Clone Stamp, Recolor) now have much smoother mouse input handling via GetMouseMovePointsEx.
- Brush tools (Paintbrush, Eraser, Clone Stamp, Recolor) now have soft brushes support via a “Hardness” setting in the toolbar.
- The Move tools (Move Selected Pixels, Move Selection) have a much better UI for scaling, moving, and (especially) rotation.
- The Move tools now support moving the rotation anchor, which changes the center of rotation.
- The new Shapes tool replaces the Rectangle, Rounded Rectangle, Ellipse, and Freeform shape tools. 27 shapes are currently available. You may move, resize, and rotate a shape, as well as reconfigure any other properties from the toolbar (color, outline size, etc.) before committing it to the layer.
- Color Picker has a configurable sampling radius, and can sample from either the current layer or the whole image.
- Gradient tool now supports a new Spiral gradient type and allows configuration of the repeat mode (none, repeat, wrapped).
- Gradient tool has improved rendering quality via dithering and antialiasing. You can control both of these with the standard antialiasing toggle in the toolbar.
- Magic Wand and Paint Bucket now allow live adjustment of Tolerance and the Origin (click location) after clicking (press Enter to commit/finish).
- Magic Wand and Paint Bucket can now sample from either the current layer or the whole image.
- Paint Bucket tool now supports anti-aliasing.
- Recolor tool can now use the color of the pixel where you click as the color to be replaced. Or, as usual, it can use the secondary color.
- Text tool now supports multiple rendering modes: Smooth, Sharp (Modern), and Sharp (Classic). These correspond to DirectWrite rendering modes of Outline, ClearType Natural Symmetric, and GDI Classic, respectively.
- Text tool now supports colored fonts on Windows 8.1.

Paint.NET 4.0 Beta 1
更新細節：
- Added a "Finish" (aka commit) button in the toolbar. It looks like a green check mark. This makes it much easier to discover how you finish a shape and then draw another one, for instance. Most of the non-brush tools support this (e.g. Move, Gradient, Magic Wand, Paint Bucket, Text).
