Qfsm is a graphical tool for designing finite state machine; it is written in C++ using the Qt library. Finite state machines are models to describe complex objects or systems in terms of the states they may be in. This release of Qfsm includes some new features, bug fixes and improvements:

• Implemented initial version of SCXML export (for 'free text' machines);
• Implemented export of vvvv Automata code (for 'free text' machines);
• Implemented VHDL test bench export;
• Overhauled documentation;
• Russian translation;
• Improvments in VHDL export;
• Bug fixes.

Glade (Gds, Lef And Def Editor) is a freeware IC layout editor capable of reading GDS2, OASIS, LEF and DEF. It's distributed under freeware license. The latest version of Glade (4.1.7) has several fixes to the non-OpenGL rendering engine. Also some bugs introduced in 4.1.6;

GTKWave is a fully featured GTK+ based wave viewer for Unix and GNU/Linux which reads LXT, LXT2, VZT, and GHW files as well as standard Verilog VCD/EVCD files and allows their viewing. The new release fixes a "big mistake";

• Emergency fix for ghw.c as it was missing a close comment causing problems with iterative generate.

Xenomai is a real-time development framework cooperating with the Linux kernel, in order to provide a pervasive, interface-agnostic, hard real-time support to user-space applications, seamlessly integrated into the GNU/Linux environment. Xenomai 2.5.0. Here is some of optimizations, cleanups and bug fixes:

• This release brings in a nios2 port. This makes Xenomai 2.5.0 available for seven architectures:ARM, Blackfin, Nios2, PowerPC 32/64 and x86 32/64;
• A new set of 64/96 bit arithmetics, optimized per-architecture, have been introduced. Because they are involved in various time-critical operations, the performance gain is noticeable on low end platforms;
• Tunable unlocked context switching, as a way to significantly reduce interrupt latency when required.

ParaView is an open-source, multi-platform application designed to visualize data sets of size varying from small to very large, structured and unstructured, time varying and static. The goals of the ParaView project include developing an open-source, multi-platform visualization application that support distributed computational models to process large data sets. It has an open, flexible, and intuitive user interface. Furthermore, ParaView is built on an extensible architecture based on open standards. ParaView runs on distributed and shared memory parallel as well as single processor systems. The binaries and sources are available for download from the ParaView website. This release of Paraview includes several new features along with plenty of bug fixes addressing a multitude of usability and stability issues including those affecting parallel volume rendering and has many GUI usability improvements including, but definitely not limited to:

Fityk is nonlinear curve-fitting and data analysis software. It allows data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt algorithm, a genetic algorithm, or Nelder-Mead simplex method. It knows about many functions (mostly bell-shaped, like Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt, and Doniach-Sunjic) and user-defined functions can be easily added. It also enables background substracting, data calibration, and task automation with a simple script language. It is being developed to analyze powder diffraction patterns, but is also used in chromatography, photoluminescence, infrared, and Raman spectroscopy, and can be used to fit analytical functions to any kind of data. In this new release of Fityk;

* GUI: Data > Editor dialog was replaced with two dialogs: Data > Table
  and Data > Edit Transformations
* added Lua bindings (configure option --enable-lua)
* a syntax to execute output from external program: command ! program [args...]
* xyConvert (which requires wx 2.9) is built by default.
  Added flag --disable-xyconvert, which must be used with wx 2.8.
* parsing of info command was rewritten, but functionality is almost the same
* bug fixes
