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:
- Upgraded to Qt5, version 5.2.1;
- Fix for AtMega-IC;
- Fix for -svg command line option, updated -help output;
- Adding a lots of new parts, e.g. Atlas Scientific sensors, Teensy 3.0/3.1 and so on;
- Remove old comment;
- Fix for pcb -> schematics ratsnest missing issue.

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.:
- Fix partial dataset evaluation issue when loading documents;
- Add HDF5 saved document format;
- Fixed crash with empty dataset and boxplot widget;
- Fix copy and paste of datasets;
- Add reflection and rotation options to vector field widget;
- Move code to use PyQt new style signals;
- Switch to scientific notation earlier when showing float settings.

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 (5.33.0) of Maxima has been released. Some changes are:
- Fix bug in mset extension stuff;
- Update list of share directories and list of share files;
- Update src/sharefiles.mk;
- Handle arguments of zeroa and zerob in round() and truncate() then add docs for truncate();
- Update docs for floor(), ceiling() and round();
- Put built-in operators on *MOPL* list;
- Update maximaMathML.
LyX is a document processor that encourages an approach to writing based on the structure of your documents (WYSIWYM - What You See Is What You Mean) and not simply their appearance (WYSIWYG - What You See Is What You Get). LyX combines the power and flexibility of TeX/LaTeX with the ease of use of a graphical interface. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. In addition, staples of scientific authoring such as reference list and index creation come standard. But you can also use LyX to create a letter or a novel or a theatre play or film script. The first release candidate of development version, LyX 2.1.0 RC1, has been released. In this new version:
- Bibtopic requires styles files to be passed via argument;
- Coloneqq not reliably displayed within LyX (fixed);
- Change potentially unsafe Ctrl+Alt shortcuts;
- Do not store Languages objects in completion words lists (fixed);
- Assertion when viewing Users Guide as LyXHTML (closed);
- Infinite recursion in ::notify (fixed);
- Fixed a crash when moving to Edit Menu after "Add Line Below";
- Fixed abort when Reverting Open All Insets in Shortcuts.lyx.
