Gwyddion / News: Recent posts

Version 3.5 “Too Direct” was released. It is a development milestone. The main focus was on decoupling widgets from the structure of GWY files. A good progress on gobject-introspection annotations was also made.

Version 2.69 “Sequential Stacking” was released. It adds an option to import an image stack and brings the usual assortment of file format support improvements. See the detailed news for the complete list of changes.

Version 3.4 “Verge of Brink” was released. It is a development milestone. The most focus was on internal clean-up and perparation for further develoment. It also added initial support for gobject-introspection, enabling the use of Gwyddion libraries from Python and other languages. However, it is still work in progress.

Version 3.3 “Moving Together” was released. It is a development milestone. Libraries were rationalised to just three, remote control was rewritten to GApplication and various cleanup continued. SVG icons are also now used directly.

Version 3.2 “Serial Reviver” was released. It is a development milestone. More deprecated GTK+ widgets were replaced. The main focus was rewritten serialisation though.

Version 2.68 “Clustersnack” was released. It brings reworked volume data clustering as well as a couple new file import modules and the usual pile of bug fixes and smaller improvements. See the detailed news for the complete list of changes.

Would you like to develop Gwyddion as a part of your PhD? Check our open position for AI in SPM data processing for life sciences, which is part of SPM4.0 MSCA project on autonomous SPM.

A brief explanation what is (and what is not) Gwyddion 3.x was added to frequently asked questions.

Version 3.0 “It lives!” was released. It is a development milestone in porting to new GTK+, Python, etc. It does not contain any new features. In fact, a number of features are still disabled or buggy. You can compile it from source code if you are interested and it should mostly work. But at this stage there is not much reason to do so.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Version 1.6 of libgwyfile was released. It fixed a bug in handling of "segments" item in GwyLawn

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.

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.

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.

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

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.

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.
