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.

Maxima is a fairly complete computer algebra system written in Common Lisp with an emphasis on symbolic computation. It is based on DOE-MACSYMA and licensed under the GPL. Its abilities include symbolic integration, 3D plotting, and an ODE (Ordinary Differential Equations) solver.
It is full featured, doing symbolic manipulation of polynomials, matrices, rational functions, integration, Todd-coxeter, graphing, bigfloats and so on. It has, also, a symbolic debugger source level debugger for maxima code.
A new version (5.32.0) of Maxima has been released. Some changes are:
- Better implementation of max-exponent;
- Update of the Plotting section of the manual;
- New options added to save output in SVG, PNG or PDF formats;
- Fixes a bug in plot2d-discrete and implements a feature requested;
- Adds several new options for the plotting programs (e.g.: grid2d, label, samexy, samexyz, xyscale, yxratio etc);
- Fixes many bugs, e.g.: Bigfloat Gamma Inaccurate for Small Inputs, Correction for $matrix evaluation, elliptic_kc(3.0) not accurate, Numeric evaluation of inverse Jacobi elliptic functions is wrong for some inputs, Erroneous limit result, fix "limit(-(3*n^2 + 1)*(-1)^n/sqrt(n^5 + 8*n^3 + 8),n,inf)" etc.

Fritzing is an open-source initiative that allows you to virtually design electronic circuits on a breadboard (although you could design circuits that aren't on a breadboard). This could save a lot of hours working on a breadboard if you have this amazing software at hand.
Fritzing can be seen as an Electronic Design Automation (EDA) tool. The input metaphor is inspired by the environment of designers (the breadboard-based prototype), so that it is easy to transfer a hardware sketch to the software by using a drag-and-drop-based GUI to copy your sketch.
In this new version of Fritzing a high-level summary of changes are:
- An handful of styling changes;
- ICSP and ICSP-less Arduino;
- Fixed an infinite loop at startup for some languages;
- Welcome View print crash fixed;
- Fixed Arduino swap crash.
