2024

2024-11-13: We are happy to announce the publication of an Measurement Science and Technology paper Stitching accuracy in large area Scanning Probe Microscopy which describes the stitching method with simultaneous scanner background estimation implemented in Gwyddion recently.

2024-11-11: Source code tarballs (and possibly other signed items) are now signed by Yeti's new GnuGP key. To make the change a bit less abrupt, version 2.67 is signed by both keys (.sig2 denoting the new signature). However, the old one will cease to be used.

2024-11-11: Version 2.67 “Twenty Four” was released. It brings several new curve map and XYZ modules, bias corrected ACF as well the usual array of bug fixes and file format support improvements. See the detailed news for the complete list of changes.

2024-06-14: We are happy to announce the publication of an Engineering Research Express paper Self-consistent autocorrelation for finite-area bias correction in roughness measurement which attempts to give a simple practical solution to the problem of finite-area bias in roughness measurement. The methods are not available in Gwyddion yet, but should appear in the next version.

2024-05-24: Version 2.66 “Pasta” was released. It is mainly a bugfix release with a number of file format support improvements and new SMM calibration. See the detailed news for the complete list of changes.

2024-01-04: Version 2.65 “Arithmetic Amends” was released. It is mainly a bugfix release with a couple of smaller improvements. See the detailed news for the complete list of changes.

2023

2023-10-29: Version 2.64 “Delayed Drifter” was released. It brings the second large batch of new volume and XYZ data processing modules as well as support for several new file formats and greatly improved support for existing ones. It also adds the XKCD Painbow false colour gradient. See the detailed news for the complete list of changes.

2023-08-01: We are happy to announce the publication of a Hardware X paper Scanning Probe Microscopy controller with advanced sampling support which gives an overview of Gwyscope. It is a low-cost open DSP controller for SPM focusing on demonstrating adaptive scanning, general XYZ data acquisition and statistical data processing at the controller level. More information about Gwyscope can be found at the project's website gwyscope.net.

2023-06-13: Version 2.63 “Voluntarily Volatile” was released. Beside the usual file format support and other improvements it brings mainly a bunch of new volume data processing modules. And more are to come. See the detailed news for the complete list of changes.

2023-04-24: Version 1.6 of libgwyfile was released. It fixed a bug in handling of "segments" item in GwyLawn.

2023-03-08: We are happy to announce the publication of a Measurement Science and Technology paper Demystifying data evaluation in the measurement of periodic structures which revisits data evaluation methods for the measurement of period/pitch of periodic structures such as gratings. A 1D grating evaluation module based on this work is under development and present in recent nightly builds.

2023-01-03: Updated gwydump MS Windows executables were published, replacing the ancient ones no longer working with the libraries packaged with Gwyddion. Both 32bit and 64bit executables are now available.

2022

2022-11-03: Version 2.62 “Getting there” was released. It is mainly continues with module code clean-up, but brings also a number of file format support and other improvements and bugfixes, as well as a couple of new curve map modules. See the detailed news for the complete list of changes.

2022-09-15: The size of equations in the user guide was corrected and they should again display reasonably sized instead of tiny.

2022-05-13: A new version of the sample standalone module was released: threshold-example-2.6. It was rewritten to use GwyParams for parameter handling. It now requires Gwyddion 2.59, but it is a lot shorter and contains basically no explicit GTK+ code. The comments were also improved. It should be a better base for writing a Gwyddion module if compatibility with older versions is not required.

2022-05-02: Version 2.61 “Fermentation” was released. It is mainly a bugfix release, with a number of smaller improvements and corrections of problems which appeared in the two previous versions. See the detailed news for the complete list of changes.

2022-03-02: The Gwyddion project received the SourceForge ‘Open Source Excellence’ award.

2022-02-11: Version 1.5 of libgwyfile was released. The library was updated to support data types added to Gwyddion in the last couple of years.

2021

2021-11-12: Version 2.60 “Lawnmower League” was released. It brings a new data type, curve maps, which are sets of curves defined in each image pixel. There are also a bunch of new graph modules and the usual file format improvements. See the detailed news for the complete list of changes.

2021-07-23: Along with data analysis, Gwyddion also offers a number of modules for generation of artificial SPM data (and patterns in general, see GIMP plug-in replacements). If you want to know how artificial data can be used in SPM, you can read our recent review in which we summarised the methods and applications.

2021-06-28: Version 2.59 “Definition Diet” was released. The biggest change was invisible, a major cleanup of module parameter handling. However, it was accompanied with many small improvements in dozens of modules. See the detailed news for the complete list of changes.

2021-02-14: We switched TeX equations in the on-line user guide from PNG to SVG. They now look cleaner, scale nicely with the page, etc. All non-ancient web browsers should have reasonable SVG support – but please report if equations do not display correctly for you.

2021-02-09: Version 2.58 “Plainly Planar” was released. It mainly fixes masked plane levelling, broken in 2.57. However, it includes a few other improvements, for instance in Renishaw support, a new perspective correction function and a new Japanese translation. See the detailed news for the full list of changes.

2020

2020-12-28: Version 2.57 “Professing Profiles” was released. Again, there are a bunch of improvements in file format support, but also new profile extraction and comparison functions, data classification using neural networks and more. See the detailed news for the full list of changes.

2020-09-17: Several new functions added to Gwyddion in the last two releases implement ideas described in our recent papers. Image terrace fitting and Graph terrace fitting implement algorithms described in the Si step evaluation paper. The new Correlation length tool was a repeatedly requested feature. However, it also helps with checking if image dimensions are sufficiently larger than the autocorrelation length for roughness measurement – as discussed in a couple of papers, one more technical and one more high-level.

2020-07-29: To get working Gwyddion packages in Ubuntu you can use the Gwyddion-SPM PPA instead of the broken distro packages (bug 1882441). The PPA also provides more current versions of Gwyddion.

2020-07-12: Gwyddion package in Ubuntu 20.04 (possibly other versions?) is broken, failing to load any modules at startup due to linking issue. See bug 1882441 in Launchpad. At present there is no known workaround aside for compilation from source code (as dscribed in the bug report).

2020-06-30: Version 2.56 “Semiscale” was released. The main improvements are in file format support, but there is also a new tool for autocorrelation length estimation and the usual bunch of bugfixes and smaller improvements. See the detailed news which contain the complete list of changes.

2020-06-08: Version 1.4 of libgwyfile was released. This is mainly a bugfix release, which also adds a couple of functions for object and item copying.

2020-06-02: Version 1.3 of libgwyfile was released. The main addition is an interface for GWY files in memory buffers. The library was also updated to handle new data types introduced in Gwyddion 2.53.

2019

2019-11-04: Version 2.55 “Zzz…” was released. It is mainly a bugfix release bringing back ZIP support in file import modules. However, there are also a few new volume data modules or a number of file format support improvements. See the detailed news for the complete list.

2019-09-22: Version 2.54 was, unfortunately, relased without ZIP support, meaning that a bunch of file formats cannot be loaded: APE DAX, OpenGPS, JPK force data, NanoObserver, NanoScanTech, Olympus POIR, Sensofar PLUx and SPMx. This affects not just MS Windows executables, but ZIP support is silently disabled also when you compile from source code. We will be releasing 2.55 in several weeks with a fix. Please use version 2.53 or development snapshots meanwhile if you need to read some of the affected file formats.

2019-09-04: Version 2.54 added two synthetic data modules, one directly inspired by an old Yeti's GIMP plug-in. We updated the replacement information to illustrate all the recently added data generators.

2019-08-27: Version 2.54 “A Small Step” was released. It fixes a large number of bugs, but also brings a dozen new modules – data process, file, graph – and various smaller improvements. See the detailed news for the complete list.

2019-06-05: Gwyddion is now available as Flatpak app, a cross-distro way of installing stable bundled applications. See the download page for more. In related news, the Fedora 30 repository should be finally working.

2019-05-09: We added a paper describing some recently added MFM data processing methods to the publication list.

2019-03-06: A patch for version 2.53 was published, fixing Gwyddion being unable to find icons and similar data on a Mac. See also Patches.

2019-02-28: A patch for version 2.53 was published, fixing a compilation error with GCC 9. It breaks compilation with other GCC versions, so only apply it when necessary. See also Patches.

2019-02-28: Version 2.53 “OMGOMP” was released. It adds OpenMP parallelisation for a bunch of data processing operations. There are also improvements in basic tools, a few new modules and some bug fixes as usual. See the detailed news for the complete list.

2018

2018-11-21: We would like to invite you to the next biannual SPM workshop which will take place in Lednice (Czech Republic), 27–29 March 2019. Registration will open in November (or December).

2018-11-15: A patch for version 2.52 was published, fixing a build failure on macOS. See also Patches.

2018-11-14: Version 2.52 “Thoroughly Transferred” was released. It brings a few new file import modules, some improvements mainly in MFM and volume data processing and quite a few bug fixes. See the detailed news for the complete list.

2018-10-17: Since Debian is – unfortunately – is going to terminate GTK+2 support, note that it will become rather difficult to install and use Gwyddion in Debian. Not much can be done except the recommendation to use a Linux distribution which values backward compatibility instead.

2018-06-26: Version 2.51 “Astronomical Almanac” was released. It brings over a dozen new modules, many of them MFM and volume data processing-related. See the detailed news for the complete list of improvements and bug fixes.

2018-04-11: Code revisions 20955–20958 were lost due to a SF.net outage. The code itself has been recommitted, however, the new revision history is not identical. If you have a working copy updated to the lost revisions, you may be getting error messages from svn. Please assume your working copy is toast and check out a fresh one if it happens.

2018-03-16: We are happy to announce the publication of the second edition of the book 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. It is accompanied with a set of freely available sample data covering various types of SPM measurements.

2018-02-02: Version 2.50 “Triangular Trap” was finally released. See the detailed news for the complete list of new modules, file format support improvements and other changes.

2017

2017-09-17: Yeti's talk Gwyddion – Open source software for SPM data analysis was added to presentations.

2017-08-28: A patch for version 2.49 was published, fixing build problems when sed is BSD sed, i.e. on Mac OS X and BSD systems. See also Patches.

2017-08-15: Version 2.49 “Window to the West” was released. As usual, it brings a bundle of new modules and various improvements – and also module bundles. The most noticeable changes are, nevertheless, a new much nicer icon set by Felix Kling and a better widget for adjusting the bazillion parameters of various algorithms. See the detailed news for the complete list of changes.

2017-08-12: Petr's talk Gwyscan – library for smart scanning paths about gwyscan was added to presentations. See also the related paper.

2017-08-11: There seems to be still some interest in GIMP image generation plug-ins Yeti wrote 15 years ago – and abandoned essentially when Gwyddion development started. Although resurrection is unlikely, the good news is that their ideas have found their way into Gwyddion synthetic data modules. We added some information about the correspondence between them.

2017-08-07: A Fedora 26 repository was added.

2017-05-11: A list of Gwyddion-related publications was added – more specifically, publications describing Gwyddion architecture and algorithms or otherwise related to the software in a fundamental manner.

2017-04-29: Version 2.48 “Magnetic Monastery” was released. It brings a bunch of MFM-related modules as well as the usual collection of new and improved file import modules and bugfixes. There is also a new translation, Brazilian Portugese. See the detailed news for the complete list of changes.

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

2016

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

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:

• 2.7.10 (or lower) for use in MS Windows
• 2.7.9 (or lower) for cross-compilation in Linux

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 SF.net 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

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 soft-hummingbird.com.

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 SourceForge.net 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

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

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 gwyddion.net. 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 SourceForge.net project upgrade have also brought a wiki and web forums. Log in to your SourceForge.net account to edit/post.

2012-07-19: Due to a SourceForge.net 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 https://svn.code.sf.net/p/gwyddion/code/trunk/gwyddion. 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.

2012-05-18: Version 2.28 was released with several new file modules and also data processing modules related to simulation of real measurements. See the defailed news for the full list.

2012-05-03: The FreeBSD port of Gwyddion was updated again after a long time and it corresponds to the current stable version 2.27 now, thanks to Muhammad Moinur Rahman.

2012-04-16: Version 2.27 was released with a couple of new files modules and some other fixes and improvements that are listed in full in the defailed news.

2011

2011-12-20: A patch for version 2.26 was published, restoring compatibility with Gtk+ 2.8. See also Patches.
