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 (5.39) of Maxima has been released. Some changes are:
- Floating point overflow handling;
- Complex numericals;
- Testsuite additions and improvements;
- Fixed bug: diff with negative order in integrate;
- Fix issue by changing how resimplification works;
- In risplit, in preparation of fixing issue;
- Correct documentation for rest;
- Fix test for orderlessp transitive;
- Fix in gcl-builds smismatch;
- Fix in timedate, round TZ.

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 2.2.2 RC1, has been released. In this new version:
- Updated Brazilian, French, German, Italian and Slovak user interface localization;
- Fixed fen2ascii script;
- Fixed preview of external material with plaintext and DocBook;
- Fixed substitution for $$Contents in external templates;
- Fixed usage of new module "Title and Preamble Hacks";
- Enable export of external material;
- Fix problem with output of branches;
- Fix output of table borders.

KLayout is a Qt-based viewer and editor for GDS2 and OASIS integrated circuit layouts for the chip design engineer.
The main objective is to focus on the basic functionality but adding some useful features that many, even commercial viewers don't have, e.g., shows the design as it is and to animate ayers to make them blink or scroll the fill pattern.
A new version of KLayout has been released. In this new mantainance release:
- Bugfix: DXF polyline mode could not be set in reader options in Ruby. A value of 3 and 4 was not allowed;
- Enhancement: A warning is displayed when an ambiguous keyboard shortcut is triggered;
- Bugfix: An assertion in the boolean processor was fixed;
- Enhancement: The marker browser now indicates if the number of markers exceeds the specified maximum and the list is shortened;
- Enhancement: Circle and Ellipse objects are treated as thin lines in DXF reader's "merge edges" mode. Hence they participate in region formation.
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.
