Codename Summer Surprise, the new version (2.20 stable) 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 this new version, e.g.;

• Added support for the new Gwyddion Simple Field (.gsf file format);
• Pixmap export: False color scale ticks are numbered;
• Rotate: Rotation angle can be a fractional number;
• libgwyprocess: Deserialization of spectra when there are selected curves actually works now;
• It is possible to export 3D as image also to other support pixmap formats, the format is determined by the extension.

• Update nzmath optional package to 1.0 and post about this to NMBRTHY;
• Add an spkg-check file for R (statistics package);
• Implement an interface to GAP3;
• Speedup testsuite using LazyFormat;
• ...and so on!

Sage 4.4.4 closed 119 tickets, all of which are available here for your reading pleasure.

Piklab is an integrated development environment (IDE) for applications based on Microchip PIC and dsPIC microcontrollers. It integrates with several compiler and assembler toolchains (like gputils, sdcc, c18) and with the GPSim simulator. It supports the most common programmers (serial, parallel, ICD2, Pickit2, PicStart+), the ICD2 debugger, and several bootloaders (Tiny, Pickit2, and Picdem). In this new version of Piklab:

Magic is a venerable VLSI layout tool, written in the 1980's at Berkeley. New versions of Magic, stable and development, has been released. In this stable distribution (Magic version 7.5.202);

On the development distribution (Magic 8.0.74);

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 some problems/bugs and adds new functions, i.e.;

• Added strace_repeat_count and appropriate menu option;
• Removed the "/File/Quit/Don't Quit" menu item if fast exit is enabled;
• Added dnd of signals from gtkwave into rtlbrowse: now the appropriate verilog code sections automatically are imported;
• More warnings cleanups.
