1. Supported and Tested Platforms

Officially tested platforms: More verified configurations (64 bits): Note: Windows platforms are supported/verified only for the sequential mode. Multi-threading capability of this release does not support Windows.

2. Supported CLHEP version

This release of Geant4 has been verified with CLHEP, release Use of a different CLHEP version may cause incorrect simulation results.
NOTE: an internal module of the relevant CLHEP classes is provided and can be used as alternative to an external CLHEP library installation.

3. Items for migration of the user code

Listed here is some relevant information on developments included in this release, some of which may require migrations in order to upgrade from release 9.x series to this release. Note that for all users a full re-installation of libraries (or a full re-compilation) and a re-compilation of user applications is required.
