openModeller is an ecological niche modelling library, providing a uniform method to model species distribution patterns with a variety of algorithms.

Both the library and the GUI have been "co-released" under the same version number: 0.3.1. There were many changes in the library (code cleanup, bugfixes, new features and performance optimizations).

Changes to the library include:

• Reimplemented serialization/deserialization mechanism using generic configuration objects (all available algorithms are now serializable).
• om_console accepts two new keywords "Output model" (file name to store the serialized model) and "Input model" (file name to load a serialized model instead of using "WKT format", "Species file", "Species" and "Map").
• New framework for test cases available (depends on the SWIG/Python interface).
• Moved normalization from the individual raster files to the "environment" object.
• Implemented Model and Algorithm separation (new interface called Model abstracts the portion of Algorithm used for evaluations).
• Implemented reference-counting smart pointers for all major objects.
• Fixed various problems with memory leaks and uninitialized values.
• Removed CSM Kaiser-Gutman from build.
• Removed SWIG/Java binding from build.
• Projected maps now have the mask extent and cell size of a specified "map format".
• Major restructuring of directories, file locations and file names.

Changes to the GUI include:

• Compatibility with the new library version.
• Models are automatically serialized (XML file).
• A new report is generated (and saved in HTML) after each modelling process.
