Roadmap and Change Log
This release is still under development and is coming along well, with a planned release date of late 2013 or early 2014. For the latest information on
its development and all the new features, check out the Paint.NET
Paint.NET v3.5.11 -
Download, released on August 17th,
The primary goal of this update is preparing for the v4.0 release: previous versions of Paint.NET will not be able to offer the v4.0 update.
Also included are some small fixes and performance improvements that have been ported over from the v4.0 codebase.
- Fixed: The Gaussian Blur effect was incorrectly calculating alpha values for non-opaque pixels.
- Improved performance of the Sharpen effect by about 25%
- Improved performance of the Median effect by about 30%
- Improved performance of the Fragment effect by about 40%
- Improved performance of the Unfocus effect by about 100%
- Reduced memory usage when many selection manipulation operations are in the history/undo stack (the undo data is now saved to disk)
- The built-in updater now supports upgrading to paint.net 4.0 (when it's available)
Paint.NET v3.5.10 -
Download, released on October 9th,
This update fixes some broken shortcut keys for the View -> Actual Size command.
- Fixed: Ctrl+Shift+A now works again as a shortcut for
View -> Actual Size (broken in 3.5.9)
- Fixed: Ctrl+0 still works for View -> Actual Size even
if 10 or more images are open (broken in 3.5.9, it would
switch to the 10th image).
Paint.NET v3.5.9 -
released on October 1st,
This update improves the "Auto-Detect" bit-depth
feature, and fixes a few small issues.
- Improved: The "Auto-detect" bit-depth setting for PNG,
BMP, and TGA now also determines which bit-depth to use
based on which one produces the smallest file size, as well
as which ones can save the image without losing fidelity.
- Improved: You can now use Ctrl+0 as a shortcut key for
View -> Actual Size, in addition to Ctrl+Shift+A and
- Fixed: Some text in the DirectDraw Surface (DDS) Save
Configuration UI was not being loaded.
- Fixed: Some DirectDraw Surface (DDS) files authored with
other software (e.g. Unreal 2004) could not be loaded.
- Fixed: In some rare circumstances, clicking on the Save
button in the toolbar would crash.
- Fixed: The Korean translation has been added back in, with the
help of Bing machine translation to cover the few remaining
strings that were untranslated.
Paint.NET v3.5.8 -
on March 5th, 2011
This update fixes some issues with the
fault-tolerant save feature introduced in 3.5.7.
- Fixed: Saving to a folder that has been moved or renamed
will display an error instead of crashing (regression from
- Fixed: Saving to a Sharepoint site will now work
(regression from 3.5.6)
- Fixed: Saving to a file that is marked as read only will
now give an error instead of crashing (regression from
- Fixed: General reliability and correctness improvements
to fault-tolerant saving
Paint.NET v3.5.7 -
on February 20th, 2011
This update improves reliability of saving, further improves Copy/Paste functionality, and fixes some other miscellaneous bugs.
- Saving an image is now fault-tolerant. If there is an
error or crash while saving, the original file will be left
- Worked around a bug in some plugins that are incorrectly
using the built-in Gaussian Blur effect. For example,
Sharpen+. Now they won't crash.
- Fixed a bug with Edit->Paste into New Image, where the
new image would be 1 pixel too wide or tall, as reported at
- Fixed a bug with the Rectangle Select tool and Fixed
Ratio selection, which would be off by 1 pixel, as reported
- When pasting an image from Paint.NET into Paint.NET, it
will be a little smarter about where it puts the image.
Previously, if the location wasn't within the viewport, it
would be placed at the top-left corner of the viewport. Now
it will find the nearest point along the edge of the
viewport to place the image.
- The EXIF rotation ("orientation") metadata is now
discarded when opening an image, which was causing
aggravation with images that could then never be reoriented
correctly using Image->Rotate
- The EXIF metadata for JPEG thumbnail data are now
- Fixed a handful of memory leaks.
- Fixed a typo in the Italian translation. In the setup
wizard it was referring to "Pain.NET" (woops)
Paint.NET v3.5.6 - released
on November 18th, 2010
This update fixes several issues
related to copy-paste, improves performance and quality for a
few adjustments, and fixes a data loss bug.
When pasting an image, Paint.NET will be smarter
about ensuring it is placed within the area that has been
- Improved the performance and quality of the Curves and
Some minor improvements to memory usage, which
should help out a few scenarios on 32-bit systems.
- Fixed: If a JPEG was loaded that had an embedded ICC
profile, and was then saved as an 8-bit or 24-bit PNG, then
the resulting file would be corrupt (32-bit PNG worked fine
- Fixed: 16-bit TGAs no longer load with the red and blue
- Fixed: Copy-paste from a Remote Desktop session will no
longer be 'shifted' by 3 pixels.
- Fixed: Copy-paste from Internet Explorer, Firefox, or
Chrome should preserve alpha/transparency.
- Fixed: Copying from Paint.NET and pasting into Windows
Live Writer should now work.
- Fixed: Taking a full-screen screenshot with Print Screen
on a multimonitor system, where those monitors don't form a
simple rectangle, will now fill the 'gap area' with
transparent instead of black. (Example: two monitors of the
same size, one of which is rotated by 90 degrees)
- Fixed: If Paint.NET is opened without specifying an
image to open, and then the default image is modified and
saved, then Paint.NET will no longer close it upon
opening another one. This was causing data loss if that
default image had layers, and was then saved in a format
that did not support layers (anything other than .PDN).
- Fixed: Some systems were showing 'red X' thumbnails for
.PDN files in Windows Explorer, instead of the real
- Fixed: The EXIF "Creation Software" saved along with
images is no longer localized. This prevents certain
languages from seeing "Paint.NET ????? v3.5.6" in the image
Paint.NET v3.5.5 -
on April 25th, 2010
This update fixes a bug when saving 8-bit images, improves
layer composition and Gaussian Blur performance, and is now updated
to support the new .NET Framework 4.0 in some cases.
Fixed the bug where saving as 8-bit PNG/GIF/BMP wasn't
always working, usually with larger images.
- Improved the performance of the Gaussian Blur effect by
- Improved the performance of all the layer blending modes
- Improved the performance of zooming with the mouse wheel
on dual-core Intel Atom systems.
- Updated to support .NET 4.0 if no other version of .NET
- Reduced download size from 4.8MB down to 3.5MB.
- Fixed a small error in the Chinese translation.
Please note that the system requirements have
been updated. For Windows XP, you must now have
Service Pack 3 (SP3) installed; SP2 is no longer
supported. For Windows Vista, you must now have Service
Pack 1 installed.
Paint.NET v3.5.4 -
February 25th, 2010
This update fixes a few small bugs, and
improves performance of the Flatten command.
- Improved performance of the Image->Flatten command by
making it multithreaded.
- Fixed the File->Save As dialog not opening to the
- Fixed a crash with certain plugins and their use of the
File Open dialog.
- Fixed a very rare crash with the toolbar's font list.
Paint.NET v3.5.3, released on
February 7th, 2010
This update fixes a few small bugs.
- Fixed DirectDraw Surface (.dds) file format support for
CPUs which do not have SSE2 (Pentium III, Athlon XP).
- Fixed an issue with the File->Save dialog related to
file type plugins that were only written for opening
- Fixed some crashes which were supposed to be "out of
- Fixed a race condition with the New Image, Canvas Size,
and Resize dialogs. If you typed extremely fast you could
cause a crash by typing a negative number and immediately
pressing OK or Enter.
Fixed a File->Save dialog issue in Win7/Vista where it could
ask you about overwriting the wrong file.
Paint.NET v3.5.2, released on
January 4th, 2010
This update resolves some feature
disparities in the Text tool between GDI (XP) and DirectWrite
(Win7/Vista). It also improves overall performance, as well as
the correctness and quality of the Move Selected Pixels tool,
the Image->Resize function, and the Hue/Saturation adjustment.
- All font face variants (e.g., Arial vs.
Arial Narrow) are now available with the Text tool in
Win7/Vista with DirectWrite.
- Bitmap font types (e.g. Courier,
Terminal, Fixedsys) are now available with the Text tool
- Fixed some bad text kerning with the
Text tool at small font sizes when antialiasing was
- For the Image->Resize function, the
quality, correctness, and performance of Bilinear
and Bicubic sampling modes have been improved. Super
Sampling also has some performance improvement.
- Improved the rendering quality for
the Hue/Saturation adjustment. Also made a new icon for
- Fixed many subtle rendering issues
with the Move Selected Pixels tool. These were apparent
when flipping or rotating a selected area.
- Fixed: The Line/Curve tool was
applying pixel snapping to the curve nodes, which caused
lines to "bend" when using the Shift key to constrain
- Fixed some extraneous CPU usage
related to unnecessary or redundant thumbnail updates.
- Fixed a few dialogs that looked wrong
with Aero glass with Remote Desktop or Virtual PC.
- Fixed a nasty memory leak with
Flatten followed by Undo.
- Fixed some issues related to effects
that took awhile to cancel. As it turns out,
drag-and-drop was enabled at this time, which easily lead to crashes or hangs.
- Some Win7 systems could not detect
that .NET 3.5 SP1 was installed, even though it was. A
fallback detection function has been added.
- For plugin authors, the Effect class
now has a pollable IsCancelRequested property. This can
be used to improve responsiveness for expensive
OnSetRenderInfo() implementations which are otherwise
- For plugin authors, the
Surface.FitSurface() method is now optimized to use
multiple threads, which improves
Paint.NET v3.5.1, released on
November 19th, 2009
This update adds a new feature for
Windows 7 users, and fixes many small issues that have been
found since 3.5's release.
- New: For Windows 7,
added taskbar progress reporting for long running operations
(effects, adjustments, Image->Resize, save, install)
- Made some corrections to the French
- Running setup with /auto will
no longer launch Paint.NET when it's done
- Fixed an issue where Paste into
New Image would refuse an image on the clipboard, even
if regular Paste would take it
- Fixed a race condition with
Edit->Paste and Image->Resize whereby it would take up
100% CPU and take between 1 minute to 1 hour to finish
- Fixed an issues with Copy/Paste
where it would leave an extra line of transparent pixels
on the left, top, right, and/or bottom edges
- Fixed lag with the paintbrush
tool that was being seen on some systems
- Fixed some issues with the
paintbrush and eraser tool being misaligned when zoomed
- Fixed a crash that would happen
at (seemingly) random times, such as after drawing with
the paintbrush tool, on some systems
- Fixed a minor and obscure
rendering glitch with the Move Selected Pixels tool
- Fixed an issue with glass over
Remote Desktop or Windows 7 Virtual PC
- Fixed a minor glitch whereby the
"Unsaved Changes" confirmation dialog could never finish
rendering the image thumbnail if one of the Move tools
Paint.NET v3.5, released on November 6th, 2009
This release focused on improving performance reliability, reducing memory usage, upgrading to the latest .NET
Framework version, and refreshing
the user interface for Aero and glass (Windows 7 / Vista).
- New: Refreshed user interface with new icons and visual
styling. On Windows 7 and Vista, it is enhanced for Aero and
- New effect: Blurs ->
Surface Blur, by Ed Harvey
- New effect: Distort -> Dents,
by Ed Harvey
- New effect: Distort -> Crystalize, by Ed
- New: Russian translation.
Performance and memory usage have been extensively
optimized throughout the entire program.
Framework 3.5 SP1 is now required, which has many built-in
Disk space usage has been reduced by
about 12MB by using NTFS compression on installation files
related to staging (.MSI) and diagnostics (.PDB).
- Compression for .PDN
images has been improved.
- Effect dialog responsiveness has been improved.
- Images open much faster, especially on
single CPU systems.
performance on most systems will be better by about 20%.
usage has been reduced when more than one image is
quality has been greatly improved when zoomed in.
- The selection
outline is no longer animated. Instead of "dancing
ants", a context-sensitive "XOR" stipple pattern is
drawn. This has allowed for improved performance and
lowered CPU consumption (and longer battery life).
- The font
manager for the Text tool has been
completely rewritten, which fixes many problems seen with
crashes and missing fonts.
- On Windows XP, the Text tool has improved
reliability and font selection (it
uses GDI instead of GDI+).
- On Windows 7, the Text
tool will use DirectWrite (instead of GDI) which gives better performance and
greatly improved quality. On Windows Vista, you may
install DirectX 11 to enable this feature; otherwise GDI
will be used.
- 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.
- It is now drastically easier to move a very small
- All installation
prerequisites are now installed automatically, such as .NET
and Windows Installer.
- Updates are now downloaded in the
background, and installed after you exit the
application. In previous versions, this was a foreground
task and you could not use Paint.NET while the update was
- Added a
"Utilities" menu. Updates, Languages, and Plugin Errors have
been moved there.
- Added a "Manage Fonts" command to
the Utilities menu. This will launch the built-in Windows
font control panel.
- Clicking the middle mouse
button on an image thumbnail will now close the image.
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.
- Fixed a crash due to an overflow that
prevented very large images from working (64-bit only).
- Fixed many other miscellaneous glitches and crashes.
- The Korean translation has been removed.
Sadly, we were unable to find the resources to complete
Paint.NET v3.36 Released:
August 26th, 2008 -
This is mostly a servicing release to make some small
improvements and to fix a few important bugs.
- Improved: Effect rendering should be a
little faster now.
- Changed: Implemented some changes to
the "Add Noise" effect that were suggested by a forum
The canvas background color is now always #c0c0c0.
- Changed: The auto-updater should now
correctly detect .NET 3.5 and newer, which will help to save
bandwidth when Paint.NET v4.0 is released (it will require
- Fixed: Paint.NET now works on a system
that has the .NET 3.5 SP1 "Client Profile" installed.
- Fixed: When zoomed in and the
cursor is to the top-left of the image (negative
coordinates), the ruler is now highlighted in the correct
- Fixed: The effect rendering system no
longer sets the "Tag" property on the configuration dialog.
- Fixed: Some incorrectly authored
plugins would cause a crash when loading their support
details (author, copyright, etc.).
- Fixed: There was a bug in the color
wheel for IndirectUI that caused it to show the wrong values
- Fixed: There was a performance problem
for effects that used the IndirectUI color wheel control.
- Fixed: In some rare cases, Paint.NET
would crash while shutting down.
- Fixed: When using the "Fixed Ratio"
feature of the Rectangle Selection tool, it would crash if 0
was specified for both the width and height.
Paint.NET v3.35 Released:
July 7th, 2008
This releases introduces a new Posterize adjustment, a new
Intersect selection mode, dramatically improved
performance for selection editing, and several small bug fixes.
Posterize adjustment, by Ed Harvey.
- New: Intersect selection editing mode.
Improved: Dramatically improved
selection editing performance for the Add and Subtract modes
(and also for Intersect). The performance used to be
dependent on image size, and thus was often unusable on
images larger than 1024x768 pixels. It is now dependent only
on selection complexity (number of polygon edges) -- the
improvement is generally between 3x and 1000x.
- New: When holding Ctrl or Alt for a
selection tool, the cursor now has a plus or minus
- Changed: The canvas background is now a
solid color instead of a gradient. The gradient was causing
certain tone misjudgments related to bright versus dark
- Changed: Shortcut key for Sepia is now Ctrl+Shift+E. The
shortcut for Posterize is now Ctrl+Shift+P.
- Changed: Hotkeys for selection modes
are now Left click for Replace, Control+Left click for Add
(union), Alt+Left click for Subtract (difference), Ctrl+Left
click for Intersect, and Ctrl+Right click for Invert (xor).
- Changed: When using a selection mode
other than "replace", it will now draw the selection outline
so that you can see both the original and resulting
selection areas. Before, it would only draw the resulting
selection area outline, which made modes such as Intersect
hard to use.
- Fixed: The Resize dialog had some
rounding errors with the "Maintain aspect ratio" feature,
which caused a few discrepancies and even a spurious "out of
- Fixed: Some quirks with the Color Wheel
control for IndirectUI-based effect plugins.
- Fixed: Several miscellaneous and rare
- Fixed: The installer would display a
bizarre error if a "blank" install folder was attempted.
- Fixed: The installer now only accepts
absolute path locations, instead of relative ones. This
fixes an ambiguity between where Paint.NET believes it is
installing itself to, and the directory that Windows
Installer actually uses.
- Fixed: Sometimes pasting would result
in a crash when certain types of malfored data were on the
- Fixed: It was possible to get around
some of the protections imposed by the IndirectUI system.
This was causing instability with some effect plugins such
as "Fern Fractal".
- Fixed: There were some issues with the
implementation of "linked" sliders for effects
based on IndirectUI.
May 1st, 2008 -
This is mostly a servicing release to fix a few important bugs.
- New: Enabled integration
Clippings, which is a high quality screen capture
utility by Kenny Kerr.
- Fixed: Fixed a crash
with the Open/Save dialogs if the Documents or Pictures
directories were either inaccessible or if the user did not
have certain file system permissions.
- Changed / Fixed: The
hotkey for Adjustments -> Levels is now Ctrl+Shift+L instead
of Ctrl+Alt+L. This was preventing certain characters, such
as the Polish 'ł', from being typed.
April 10th, 2008
release adds an Italian translation, a new "Fragment Blur" effect,
ability to save PNG images at 8- and 24-bit color depths. For
developers, the IndirectUI system has some new controls, some
new constraint rules, and can now be used for file type plugins.
- New: Italian
- New: Ability to save
PNG's at 8- and
24-bit color depths.
- New: Ability to save
BMP's at 8-bit color depth.
- New: "Auto-detect"
bit-depth option for PNG, BMP, and TGA file types. It will
analyze the image and determine the lowest bit-depth that
can still save the image without quality loss.
- New: "Fragment" blur
effect, by Ed Harvey
- New: The "Polar
Inversion" distortion effect has been enhanced to allow
changing the rendering offset, and the behavior for "edge"
pixels (clamp, reflect, or wrap).
- New: For developers, added a Color
Wheel control to IndirectUI for use in effect plugins.
- New: For developers, added ability to
customize certain properties of the effect configuration
dialog via IndirectUI.
- New: For developers,
IndirectUI can now be used to write configuration
UI for file types.
- New: For developers,
IndirectUI has a new radio button control type for
enumerations, and some new property constraint rules.
- Changed: Most effects and adjustments,
including plugins that use IndirectUI, have been visually
refreshed. The new look is cleaner and more compact. These
changes are shown in more detail at
- Fixed: Various UI issues with the
- Fixed: When pasting text into the Text
tool with Ctrl+V, it would hide the nub for moving the text.
- Fixed: If the startup tool was set to
the Zoom or Pan (Hand) tool, then the toolbar would render
- Fixed: Thumbnails for PDN images now
include transparency, which improves their appearance in
- Fixed: In some cases, an exponential
property slider would get "stuck" at some values when using
up/down keyboard keys. This mostly affects some effect
- Fixed: When using keyboard navigation,
sometimes the File menu would scroll its items out of view.
- Fixed: Some crashes that were tracked
down to out-of-bounds coordinate values in certain effects.
- Fixed: The installer
would fail if Paint.NET had never been installed before, and
was being installed to any non-default directory. This bug
only affected version 3.22.
January 12th, 2008 -
This release fixes a few minor bugs and adds a new, much-needed
Reduce Noise effect.
- New: "Reduce Noise" effect.
- Changed: Ctrl+W will now close Paint.NET if zero images are open.
- Fixed: In Windows XP, when launching web content, sometimes Internet Explorer was used instead of the user's chosen default browser.
- Fixed: The Unfocus effect was not handling alpha values properly.
- Fixed: The Brightness / Contrast adjustment was only displaying its text in English.
- Fixed: The /auto parameter for the installer now correctly allows for an automated installation. This was
inadvertently broken in 3.20.
Paint.NET v3.20 Released: December 12th, 2007
This release adds numerous enhancements and tweaks to the
built-in effects, a re-organized Effects menu, a new and much
easier system for effect plugin development,
better error handling for plugins, and the ability to draw Fixed
Ratio and Fixed Size selections with the Rectangle Select tool.
It also includes the customary list of tweaks and fixes.
- Rectangle Select tool can now draw selections based on a
Fixed Size or Fixed Ratio setting.
- The selection combination mode is now accessible from
the toolbar (Replace, Add, Subtract, Invert ("xor")).
- The "flood mode" for the Magic Wand and Paint Bucket
tool are now accessible from the toolbar (Continuous, or
- Reorganized the Effects menu so that all effects are
classified under submenus named Artistic, Blurs, Distort,
Noise, Photo, Render, and Stylize.
- Improved rendering quality for the Motion Blur
- Enhanced the Radial Blur effect so that the center of
blurring can be chosen, as well as the quality.
- Enhanced the Zoom Blur effect so that the center of
zooming can be chosen.
- Enhanced the Bulge distortion effect so that the center
of "bulging" can be chosen.
- Enhanced the Frosted Glass distortion effect in several
ways: 1) performance has been improved from between 1,000%
to 10,000% depending on image size and property settings, 2)
the scatter radius can now be set up to 200 pixels, 3) a
"minimum" scatter radius can be chosen, 4) a smoothness
setting is now available.
- Enhanced the Tile Reflection distortion effect by adding
a Quality property.
- Enhanced the Twist distortion effect by 1) allowing
counter-clockwise twisting, 2) allowing the size of the
twisted area to be configured, 3) allowing the
location/center of twisting to be chosen.
- Enhanced the Add Noise effect by adding a "coverage"
- New Mandelbrot Fractal and Julia Fractal render effects.
- New IndirectUI system for plugin authors so that they
can develop much more sophisticated effect configuration
dialogs with a fraction of the amount of work that used to
- If an effect plugin crashes, it is much more likely that
Paint.NET will be able to recover from the error.
- The option to restart Paint.NET will then be provided as
a recommended course of action.
- If an effect plugin fails to load, or is blocked from
loading, then a "View Plugin Load Errors..." item will be
added to the File menu which can be clicked on to show the
error and/or diagnostic information.
- Improved the cursors for the Magic Wand and Paint Bucket
- Ctrl+Alt+0 now works for View->Actual Size (aka, "Zoom
to 100%"), which is a shortcut key that other software uses
- Updates are now installed faster by only creating one
System Restore point instead of two (it used to implicitly
create one for uninstall, then one for the reinstall).
- Lots of little bug fixes.
Paint.NET v3.10 Released: August 23rd, 2007
This release adds two new
effects originally written by David Issel ("BoltBait"), support for the DDS filetype originally
written by Dean Ashton, as well as many small bug fixes and some visual fit and finish.
v3.08 Released: June 1st, 2007
- New: Soften Portrait effect, by
- New: Ink Sketch effect, by David
- New: DirectDraw Surface (DDS) file
format support, by Dean Ashton,
http://www.dmashton.co.uk/ . Improved from the original
source code by optimizing the DXT compression library
("Squish") to take advantage of multiple cores /
- New: "Paint.NET Search", available
from the Help menu (shortcut key is Ctrl+E), allows you to
search for Paint.NET help, forum posts, tutorials, plugins,
and other related material:
http://searchpaint.net (Note: This feature is only
available in English.)
- Improved: Visual fit-and-finish
for the Layers window.
- Improved: Visual fit-and-finish
for the close / 'X' button on image thumbnails.
- Improved: Small (about 5-10%)
performance improvements for some effects such as Oil
Painting, Frosted Glass, and Gaussian Blur.
- Improved: Increased max brush size
to 500, as per forum members request.
- Improved: Expanded list of
available font sizes up through 288.
- Changed: The keyboard shortcut key
for the Color Picker is now 'k'. This makes it so that the
toolbar option, "After click: Switch to previous tool", is
not useless for those using the keyboard shortcuts.
- Fixed: In some cases, undoing an
action that removed a layer would result in the un-removed layer not showing up until you resized the Layers window
- Fixed: Pressing F1 from the main
window no longer launches the online help in two browser tabs.
- Fixed: Adding a new layer now adds
it above the currently active layer, instead of at the very
top of the layer list.
- Fixed: Merge Down now activates
the merged layer instead of the one above it.
- Fixed: In Vista, clicking on a URL
link from the installer will no longer launch the web browser with inherited,
- Fixed: Pressing Ctrl+[ no longer
cancels out of drawing a line/curve, but instead decreases
the brush size by 5 as expected.
- Fixed: Ctrl+clicking on the brush
size +/- buttons now changes the brush size in increments of
- Fixed: Save Configuration dialog
would "creep downward" from its last position every time it
was opened again.
- Fixed: TGA codec now saves the #
of alpha bits to the image descriptor byte. This was causing
some other applications to load TGA files saved with
Paint.NET as solid black images.
- Fixed: Clicking the 'X' to close
the Layer Properties dialog was not reverting changes made
to the layer while the dialog was open.
- Fixed: Installation will not
proceed unless Paint.NET is closed, and will also not allow
Paint.NET to be opened until installation is completed. This
helps to ensure a fully coherent and complete installation
- Fixed: If a file failed to open,
and there were no open images, and the user pressed either
the Zoom In or Zoom Out toolbar buttons, then Paint.NET
- Fixed: In Vista, it was possible
to crash the Save As dialog by typing a filename that was
- Fixed: In Vista, it was possible
to crash the updater if you let the UAC prompt time-out.
- Fixed: It was possible to crash
Paint.NET on some systems by clicking on a tool in the Tools
window while the "Save As" dialog was open.
This is mostly a service release that fixes some bugs, while
also improving keyboard / accessibility cues for some dialogs.
v3.07 Released: May 8th, 2007
- Fixed: Pasting an image from Office 2003
applications now works (e.g. Excel 2003 graphs).
- Fixed: Some dialogs were not indicating which
command button was the default. These buttons now have a
highlight to indicate which one will be activated if the
user presses Enter or Space.
- Fixed: Some minor keyboard navigation issues with
- Fixed: Performance issue with the File->Acquire
submenu taking a long time to appear
- Fixed: Window activation issue when the Print
wizard was finished / closed
- Fixed: Crash when there was 1 image open and the
user pressed Ctrl+Q and then Ctrl+W
- Fixed: Minor performance issue if the user had 1
modified image open and then canceled the "Save changes?"
- Fixed: Misbehaving filetype factory
implementations (plugins) will no longer cause a crash
This update enhances the Line/Curve tool, significantly reduces
the download size, and fixes some bugs related to opening and
saving files in Windows Vista.
v3.05 Released: March 29th, 2007
- New: Line/Curve tool has been enhanced to allow
drawing arrowheads, and to draw with various dashed- and
- New: Image tab thumbnails now have an indicator
if the respective image has unsaved changes (an orange
asterisk is shown).
- Improved: The Save Configuration dialog (choose
JPEG quality, etc.) now allows you to maximize it. It also
remembers its relative location and size.
- Changed: The help file / documentation is now
hosted online. This has reduced the download size by more
than 3 MB, and will also allow us to provide translations
without ballooning the size of the download (each language
would have added between 2 and 4MB).
- Changed: The "image list button" (downward
triangle) is also shown when only 1 image is open (it used
to only display if 2 or more images were open). This is
being done for the sake of consistency.
- Fixed: Some operations would reset the selected
layer to the first/lowest layer. This selection is now

This is a small update that fixes a few bugs that have been
found since 3.0 was released.

This major release introduces a new
multi-document interface (MDI), availability in 8 languages, a
highly-requested interactive gradient tool, four new effects, a
user-definable color palette, lower disk space usage for scratch
files, and a generally cleaner and improved user interface.

- Simple and intuitive tab-based multi-document user interface
- Now available in 8 languages: English,
Chinese (Simplified), French, German, Japanese, Korean,
Portuguese (Brazil), and Spanish
- Interactive Gradient Tool that
makes it very easy to draw and then fine-tune placement and
coloring of a gradient.

to just the color wheel)
- New effects: Clouds, Median, Unfocus,
Outline, and an improved Sharpen
- More intuitive and more powerful toolbar

Released: August 31st, 2006
This small release adds a new effect and fixes a few small bugs.
- New effect: Zoom Blur
- Fixed: DPI was not being saved or loaded correctly for
file types other than PDN and JPEG
- Fixed: Text Tool now works with Alt+#### special
character entry without moving the cursor
- Fixed: Loading PNG images with alpha was often resulting
in incorrect, off-by-1 color values
Released: August 2nd, 2006
This is a small interim release that includes many of the
popular effect plugins we have written that users have enjoyed
using with Paint.NET v2.6x. We have decided to release this as a
".1" update now so that more users may benefit from these
plugins, as opposed to waiting until the final release of v3.0
to include them (which could be awhile).
With this release we have also refreshed Paint.NET's system
requirements. We now list 256 MB as the minimum memory required
instead of 128 MB. This is in line with what we have seen to be
a more reasonable minimum system for using Paint.NET. Also,
Windows XP users must now have SP2 installed (SP1 was required
before), Windows 2000 users must have SP4 installed (SP3 was
required before), and Windows Server 2003 users must have SP1
installed (no SP was required before).

- New effect: Bulge
- New effect: Polar Inversion
- New effect: Tile Reflection
- New effect: Twist
