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.

LabPlot is a KDE Application for plotting and analysis of 2d and 3d functions and data.
LabPlot allows you to work with multiple plots which each can have multiple graphs. The graphs can be produced from data or from functions. All settings of a complete set of plots can be saved in a project files.
LabPlot also provides a component for easily viewing the project files in Konqueror.
Since the last stable release, version 2.0.0, some changes are done:
- Fixed wrong scaling of legend's text labels in pdf-export;
- Fixed memory corruption in CartesianPlotDock that can lead to crashes.

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.
