The second public release of OGDF has been released today. This release focuses on improved usability, but also contains new functionality. Highlights of the new release are:

• A new algorithm for planar augmentation with fixed embedding, and extended functionality for drawing graphs with a given planar embedding.
• A new class DualGraph for representing the geometric dual graph of a combinatorial embedding.
• Sugiyama layout now produces drawings with given node ranks that are also respected across different connected components.
• Hashing functions can now be passed as template parameters; the implementation of two-dimensional hash-arrays has been revised and allows now using different types for each index. Array-based classes have now an optional template parameter for the index type.
• Unified naming conventions and interfaces; significantly improved documentation.
• Improved build system, including support for compiling with Osi Coin in Visual Studio and creating projects for Visual Studio 2003.
• The library is now licensed under GPL v2 or v3 (you have the choice) with special exceptions allowing to link against LP-solver libraries.

Please refer to the change-log for further details.

The first hotfix v.2007.09_a for Jacaranda has been released and is available at the download page. It fixes a bug that occurs when using OGDF with Coin.

The first public release of OGDF (v.2007.09, Codename “Jacaranda”) goes online, including this website, forum, and doxygen-documentation.
