Objective Caml is the latest implementation of the Caml dialect of ML. It has full support for objects and classes combined with ML-style type reconstruction, a powerful module calculus in the style of Standard ML (but retaining separate compilation), a high-performance native code compiler (in addition to a Caml Light-style bytecode compiler), and labeled arguments with possible default value.

CodeViz is a call graph visualisation tool which uses a variety of different data collection methods to generate its call graphs. Using a modified version of the GNU Compiler, very accurate call graphs that precisely reflect the compiled code may be created. If using a compiler is undesirable, CodeViz is able to directly parse C/C++ code itself, and even analyse binaries with objdump, so it will work if the source isn't available.

Yap is a high-performance Prolog compiler developed at LIACC, Universidade do Porto. Its Prolog engine is based on the WAM (Warren Abstract Machine), with several optimizations for better performance, and achieves performance comparable or exceeding that of commercial Prolog systems. Yap is largely compatible with the major Edinburgh Prolog systems, and has been ported to most 32-bit and 64-bit Unix based platforms. A Windows port is also available.

SDCC is a freeware, retargettable, optimizing ANSI-C compiler. The current version targets Intel 8051-based MCUs, the Zilog Z80, and the DS390. Targets for the Microchip PIC and Amtel AVR series are under development, and the compiler can be retargeted for other 8 bit MCUs or PICs. The entire source code for the compiler is distributed under GPL. SDCC uses ASXXXX and ASLINK, a freeware, retargettable assembler & linker. SDCC has extensive MCU (8051)-specific language extensions, which lets it utilize the underlying hardware effectively. It includes a source-level debugger/simulator and can generate debug info for the NoICE debugger.

Changes:
This release added a predefined preprocessor macro for holding SDCC's subversion revision number, various preprocessor macros, an updated preprocessor, multiple infiles for sdcclib, support for many PIC devices, generation of cdb debug info for various platforms, tail call optimization for functions that take no parameters on Z80, and improved multiplication of unsigned chars on Z80. There were also numerous enhancements and bugfixes.

UMLSpeed is a compiler for a C-style language of UML notation. It can produce SVG UML diagrams and XMI documents and generate source code in various languages.
