2017-01-18: A Fedora 25 repository was added. We are sorry for the delay.


2016-11-18: Version 2.47 “Pythocalypse” was released. It would be mostly a bugfix release, repairing selections that did not work properly in several modules. Except for one thing, a complete overhaul of pygwy (including a few API changes). And finally, Python scripting is also described in the user guide now. See the detailed news for the complete list of changes.

2016-10-31: A patch for version 2.46 was published, fixing broken function gwy_selection_set_data() that affects selections in Correct Affine, Measure Lattice, Straighten Path and a few other functions. See also Patches.

2016-10-18: A patch for version 2.46 was published, fixing compilation failure of the JPK scan file module when minizip is not available. See also Patches.

2016-10-14: Version 2.46 “Lichen Logistics” was released, bringing geometrical shape fitting, a new grain marking function, editable toolbox, new file modules and lots of other improvements. See the detailed news for the complete list of changes.

2016-09-04: Gwyddion has conquered space! The analysis of comet dust images from the Micro-Imaging Dust Analysis System (MIDAS) in the famous Rosetta space probe studying Comet 67P/Churyumov-Gerasimenko employed Gwyddion. See the ESA blog post and the full paper in Nature.

2016-07-21: A Fedora 24 repository was added. In related news, a patch for version 2.45 was published, fixing broken installation of API documentation with gtk-doc 1.25+ (which can in turn break package builds). See also Patches.

2016-07-20: A new version of the sample standalone module was released: threshold-example-2.5. A bug affecting the Mask mode was fixed and the handling of settings now more closely matches a typical Gwyddion module. A few pieces of the code were also slightly modernised (without increasing minimum required Gwyddion version).

2016-04-27: Version 1.2 of libgwyfile was released. The library was updated to handle new data types introduced in Gwyddion 2.45.

2016-04-26: Version 2.45 “Scatter and Slither” was released with a large number of new features, user interface improvements – and also initial native XYZ data support. See the detailed news for the complete list of changes.

2016-03-20: Some results, the ‘right’ values and remarks to the user influence survey are now available. See the description of each individual task for a link to the results and remarks. There may be some further elaboration and refinements, anyway, the results will hopefully satisfy your curiosity for now.

2016-03-01: The user influence survey is now closed. Thanks all who participated. We will publish the ‘right’ values and some remarks here after the Nanoscale conference.

2016-01-31: We have received a fair number of responses in the user influence survey so far and would like to thank all who participated. The survey form will be open to the end of February (which is also when the MS Windows installer will finally stop advertising it).

If you have not tested your data processing skills yet please download the survey images and fill your best estimates in the form. Thanks!

2016-01-12: Version 1.1 of libgwyfile was released, fixing a couple of bugs and improving error reporting and MSVC support.

2016-01-11: Version 2.44 “Entropy Everywhere” was released, bringing a few new features, but mainly lots of bug fixes and file format support improvements. As usual, the detailed news lists them all.


2015-12-20: A Fedora 23 repository was added. Note there were a few problems with various auxiliary developer scripts (cross build, night build, …) in F23. The scripts should be generally fixed in svn now.

2015-11-16: Complete MSVC development package is now available for Gwyddion compilation and development with Microsoft Visual Studio 2015. The package was prepared for Gwyddion 2.43 (the last stable version) and is still under development. Feedback is welcome.

2015-12-14: Please participate in our user influence survey in which we are trying to characterise the influence of humans on quantitative AFM results. The survey is fun because it consists of actual data processing (as opposed to just filling some boring forms) and it should not take more than several minutes of your time. At least unless you decide to figure out the absolutely best possible data processing procedures, in which case it can take an arbitrarily long time…

2015-12-10: If you use pygwy in MS Windows please avoid the Python 2.7.11 package (the latest one at this moment) because it causes a crash during Gwyddion startup. To stop the crashes once Python 2.7.11 has been already installed it is not sufficient to downgrade to a lower version. Apparently it is necessary to not only uninstall Python but also delete manually C:\Python27 and then reinstall all Python packages afresh. Known good versions:

2015-11-25: Version 2.43 “Respectable Rotunda” was released. The number of improvements and bug fixes is large but they are scattered all over the program. See the detailed news for their full list.

2015-11-02: Broken Fedora 22 repository causing the RPM signature check to fail with ‘No such file or directory’ was hopefully fixed.

2015-10-07: Version 2.42 “Even Enlightenment” was released. The change everyone will probably notice is the new line correction module. There are however plenty of other improvements. See the detailed news for a full list of changes.

2015-07-29: We lost a few recent commits in the restoration of subversion repository from backup. The corresponding changes have been recommitted and subversion should be working normally now. However, the revision history since r17212 (including) has changed.

It is recommended to check out fresh working copies of all svn modules and transfer any changes you might have to the new copies. If you have a working copy updated to a r17212 or later, you must check it out afresh. If you observe anything odd with subversion please report it.

2015-07-16: There was a major outage of services due to a storage failure. File download works, but subversion, discussion, etc. are out of order at this moment. Details can be found at the SourceForge blog.

2015-07-13: Version 1.0 of libgwyfile was released. Several bugs were fixed since version 0.9 and MS Windows support was greatly improved. The library is considered stable now.

2015-05-26: Version 2.41 “Moderate Memories” was released with a large number of smaller improvements and bug fixes. See the detailed news for a full list of changes.

2015-03-31: Version 0.9 of libgwyfile was released. This is a beta version. All planned functionality is generally present, however, it might not be tested properly.

2015-03-13: A Fedora 21 yum repository was finally added. We are sorry for the long delay.

2015-02-07: Version 2.40 “Mean Medians” was released. It contains several new modules and features, however, as nothing was completely rewritten this time and some bugs were fixed, it should be even more stable than the usual stable. See the full list of changes for details.


2014-12-24: The first public version of libgwyfile was released: libgwyfile-0.8. The generic GWY file functionality is complete, however, most functions for convenient reading and writing of Gwyddion GWY files are still missing.

2014-12-07: Work has started on libgwyfile, a small MIT-licensed embeddable library for reading and writing of GWY files. No versioned release has been made yet but it is taking shape fast.

2014-11-14: Version 2.39 “Magnitude and Direction” was released with several new file modules, a new translation and other improvements. The most anticipated feature is, however, probably the rewritten image export. See the full list for details.

2014-09-26: A patch for version 2.38 was published, fixing a crash in Statistical Functions tool when the table is saved to a file. See also Patches.

2014-09-18: A new version of the sample standalone module was released: threshold-example-2.4. It includes support for integrated help, introduced in Gwyddion 2.38, and fixes version check issues. So the sample module is still compatible with older versions of Gwyddion.

2014-09-18: Version 2.38 “Index Infiltration” was released, featuring an integrated help (sort of), a bunch of new file modules, pygwy and volume data processing improvements and more. The detailed news contains the full list.

2014-07-22: The sample standalone module, was moved to Applications, reducing the download page clutter a bit.

2014-06-27: Version 2.37 “Too Technical Tears” was released. It contains a number of mask and grain-related improvements but also a new file module, synthesis module and lots of other goodies. See the detailed news for the full list.

2014-06-13: A page with tutorials was added, including the nice set of video tutorials by Waldemar Smirnov originally published at

2014-06-06: The on-line module list is now available in all languages for which a user guide translation exists. The links in language version of the list point to the documentation written in the same language.

2014-04-07: We are happy to announce the publication of a Measurement Science and Technology paper Independent analysis of mechanical data from atomic force microscopy which deals with independent volume force-distance data fitting. The integration of the methods described there to Gwyddion is underway, at least a part should appear in the following version.

2014-04-03: Download links that point to the file repository were corrected to point directly to the actual files. We are sorry for the inconvenience when they were being redirected to the repository root.

2014-04-02: Version 2.36 “Casual Collider” was released. The main new features are three synthetic data modules but there was a bunch of other changes, see the detailed news for the full list.

2014-03-03: A new version of the sample standalone module, threshold-example-2.3, was released. It includes support for logging of data operations which was introduced in Gwyddion 2.35. The logging support is compiled only if a sufficiently new Gwyddion is found so the sample module is still compatible with older versions.

2014-03-02: Version 2.35 “Record Rampage” was released. See the detailed news for the full list of changes.


2013-12-18: Updated MS Windows installers, denoted 2.34-1, were released to correct the crash when Gwyddion is run in Italian.

2013-12-16: A patch for version 2.34 was published, fixing a crash when Gwyddion is run in Italian. See also Patches.

2013-12-15: Version 2.34 “The Frame Fungus” was released. It brings new affine distortion correction and Otsu's thresholding modules and a number of NT-MDT improvements – among lots of other changes that are all listed in the detailed news. It also brings some toolbox tweaks, which requires the obligatory XKCD reference.

2013-12-13: A new version of the sample standalone module, threshold-example-2.2, was released. It contains updated cross-compilation instructions and some small bug fixes.

2013-11-10: Maybe you did not know that the Gwyddion toolbox can be customised and reorganised for faster access to functions you use often. Even though it has been possible for a long time, no documentation how to do it existed. But now it does.

2013-10-17: Version 2.33 “Travelling Tips” was released. This is mostly a bugfix release although it contains some improvements and one new file module. See the detailed list of changes for more.

2013-09-08: Version 2.32 “Barrel of Bricks” was released. The biggest change is the support for volume data as a first-class data type. See the list of changes for a detailed list of what is new. If you use the 64bit MS Windows package it is recommended to upgrade by uninstallation of the previous version and installation of the new version.

2013-04-01: Petr's talk Use of Gwyddion libraries for your little tasks was added to presentations.

2013-02-21: Version 2.31 “Sixty-four Sharp Splinters” was released. It was long in the making so the list of changes is also quite long.

2013-02-19: MS Windows development snapshots are released as both 32bit and 64bit packages. The Win64 packages are still somewhat experimental and do not include pygwy yet. If you are interested in 64bit MS Windows support please help with testing.


2012-12-07: A patch for version 2.30 was published, fixing crashes if an attempt is made to change the mask colour in various data processing functions. The fix has aleady been present in the nightly builds for some time. However, raising the awareness of this annoying bug will, hopefully, increase the chance the fix finds its way into third-party Gwyddion packages.

2012-12-07: We are happy to announce the publication of a book on Quantitative Data Processing in Scanning Probe Microscopy by Elsevier. It includes descriptions of many ideas in (and behind) Gwyddion, as well as basics of different physical quantities measurements and interpretation using Scanning Probe Microscopy.

2012-10-11: A yum repository for Fedora was created at Its primary purpose it to ease the setup of a cross-compilation environment, nevertheless, it also contains a native Gwyddion package you can use in Fedora.

2012-09-21: Version 2.30 “Circular Creatures” was released, with new grain quantities, rewritten neural network module, some Win32 improvements and the usual bag of file format support fixes and other small changes. See the the complete news.

2012-07-25: A new Win32 installer denoted 2.29-1 was released, correcting an odd startup warning about python27.dll appearing on some systems if Python was not installed.

2012-07-20: Version 2.29 “Is It Raining Unicorns Or What?” was released and it should please all Python scripting fans because the MS Windows package now comes with pygwy included while on Unix a standalone gwy module is available now so you can run Gwyddion Python scripts outside Gwyddion. And median line levelling now supports masking. If you think this is not enough see the full list of good news.

2012-07-20: The project upgrade have also brought a wiki and web forums. Log in to your account to edit/post.

2012-07-19: Due to a project upgrade, the subversion URLs have changed. You will probably need a fresh checkout with the new URL for each module. For a simple read-only HTTP access check out for instance See the on-line repo browser for other options.

2012-07-15: A new version of the sample standalone module, threshold-example-2.1, was relased. The main change is the removal of MSVC files and support for cross-compilation for Win32 in Linux.

2012-06-06: A page with Gwyddion presentations was added, only containing three at this moment. More should gradually appear.

2011-05-15: A makeshift replacement for the CIA commit overview is available at

2011-05-12: The CIA service, where Gwyddion subversion commits could be watched, seems to be closed for good. At present, the closest substitute is probably the SourceForge news feed which, unfortunately, lacks commit messages and changed files in the overview.

2011-04-28: A patch was published, fixing termination of the program if freehand drawing is used in Mask Editor tool. See also Patches.

2011-04-18: I was horrified and disgusted by finding that some microscopy software saves data as the plug-in proxy internal(!) .dump files. Do not do this. Really. Use GSF instead. Anyone caught writing software that saves .dump files will be hanged at sunrise on the nearest plane tree.

2011-04-08: Version 2.24 “Squirrel in the Stable” was released; this is mostly a bugfix release. The defailed news lists the changes.

2011-03-08: The MS Windows installer of version 2.23 contained some bits not up to date with the final 2.23 release, noticeably translations, and the installed program also confusingly advertised itself as version 2.22.
