Thus e.g. release 1.0.2a of the distribution file is the present implementation of JEEP 1.0. The release 1.0.3 of the manual also documents JEEP 1.0. A change of minor release number indicates added functionality that should not affect input compatibility with older releases. Changes of the patch level are typically only due to correction of errors, and do not reflect any change in functionality.
Additional potentials are available in the database of pseudopotentials in JEEP format.
