OpenFOAM version 3.0.1 is a patch release of version 3.0.0 that fixes critical bugs and improves usability and consistency in the code. As a patch release, we strongly recommend users of v3.0.0 upgrade to this version; users of the Ubuntu pack (openfoam30) will receive 3.0.1 as part of a system upgrade, e.g. with “apt-get upgrade”. Version 3.0.1 is distributed as:

• a packaged installation for Ubuntu Linux — the simplest installation option for OpenFOAM;
• a source pack for compilation on other Linux distributions.
