The SRecord package is a collection of powerful tools for manipulating EPROM load files. It reads and writes numerous EPROM file formats (e.g. Motorola S-Record, Intel, Tektronix, Binary and so on). These file formats may be read and written. Also, C array definitions for output only. The SRecord package has filters, generators and tools include in the SRecord package. In this new version;

• There is a new MsBin (Windows CE Binary Image Data) file format, supported for both reading and writing;
• The lintian(1) warning about hyphen in the manual pages has been silenced, by careful use of -, and - as appropriate. The lintian(1) warning about the undefined .XX macro has been silenced, by making it conditional;
• The code will build without libgcrypt.

       * The lintian(1) warning about hyphen in the manual pages has been
       silenced, by careful use of -, and - as appropriate. Sure makes some of
       the sources ugly, tho.  The lintian(1) warning about the undefined .XX
       macro has been silenced, by making it conditional.

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. In this new version of Fritzing;

• Revised footprints for many parts (bigger pads for easier manual production);
• New parts: customizable DIP & SIP ICs (no need to fiddle with the graphics outside of Fritzing anymore), customizable Resistor (any value is now allowed), editable labels for DIP, SIP and mystery parts, pin headers, screw terminals and mystery parts in any length and so on;
• Many parts editor bug fixes;
• ...and a lot more bug fixes and improvements.
