A new version, 2.35 stable codename "Record Rampage, of Gwyddion, a modular program for SPM (Scanning Probe Microscopy) data visualization and analysis has been released. There are various improvements, bugfixes and new features in the application, libraries and modules, e.g.:
- A log of data modification operations is recorded for each channel and volume data. A viewer of data processing operation log is available in the right-click menus. Logging can be enabled and disabled in the Edit menu;
- A workaround for toolbox menus disapparing in Unity was implemented;
- libgwyapp: Functions for logging of data processing operations were added;
- libgwydggets: Graph window shows reasonable cursor coordinates with logscale axes;
- OME TIFF (new): Import Opem Microscopy Environment (OME) TIFF files;
- HDR image: 32bit and 64bit integer samples as well as 32bit and 64bit floating point samples are supported;
- Plain BigTIFF images can be loaded;
- Fixed bug Nanoscantech: Problems with loading 4d jumping mode spectroscopy;
- NanoScan: Files with namespace are recognised.

GTKWave is a digital waveform viewer useful for examining the output of various digital simulators and an analysis tool used to perform debugging on Verilog or VHDL simulation models. With the exception of interactive VCD viewing, it is not intended to be run interactively with simulation, but instead relies on a post-mortem approach through the use of dumpfiles.
GTKWave as a collection of binaries is comprised of two interlocking tools: the gtkwave viewer application and rtlbrowse. In addition, a collection of helper applications are used to facilitate such tasks as file conversions and simulation data mining. The new release fixes some problems/bugs and adds new functions/features, e.g.;
- Added /Data Format/Popcnt function for ones counting;
- Updated VCD ID generation in various helpers to use a faster and equivalent algorithm;
- Updated LZ4 for version r113;
- Fix to regex search to remove duplicate signal names because of faulty dumpers;
- Added very fast I/O write capability to fst2vcd.
Veusz is a scientific plotting package written in Python. It uses PyQt and Numarray. Veusz is designed to produce publication-ready Postscript output. Veusz provides a GUI, command line and scripting Python interface to its plotting facilities. The plots are built using an object-based system to provide a consistent interface allowing complex layouts to be designed. Datasets can be interactively modified or created from within the program. It also allows for manipulation and editing of datasets. In this new version of Veusz there are various improvements, bugfixes and new features, e.g.:
- Include free-desktop appdata, MIME and desktop files;
- Additional embedding interface fixes for Python 3;
- Fix crash when changing range of broken axes interactively;
- Fix object deletion crash in setting menu;
- Check output dataset is not same as an input for histograms;
- Fix for compilation on Qt 4.6;
- Fixes for formatting strings, including fixes for arguments of the extended %Vg format and properly supporting %%

Ngspice is a general-purpose circuit simulation program for nonlinear and linear analyses.
Circuits may contain resistors, capacitors, inductors, mutual inductors, independent or dependent voltage and current sources, lossless and lossy transmission lines, switches, uniform distributed RC lines, and the five most common semiconductor devices, i.e.: diodes, BJTs, JFETs, MESFETs, and MOSFETs.
Ngspice was created in C with the aid of GNU extensions, so it will run in Unix-GNU/Linux operating system provided with the proper compiler installed. Several new features have been added to ngspice-26, improving its applicability and compatibility:
- Many small bugs removed;
- Handling of libraries updated;
- Improved code compliance;
- FFT command optionally using fftw3 (new feature);
- New functions have been added: asinh, acosh, atanh, pwr;
- 'temper' in behavioural devices (new feature);
- Check for SOA, Safe Operating Area (new feature);
- Basic .if/.else block (new feature);
- Area Calculation Method (ACM) for BSIM3.3.0 (new feature);
- Updated pdf manual and other documentation.
