1. Supported and Tested Platforms

Platforms: More verified and tested 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 2.2.0.4. 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. 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.

6. Known Run-Time Problems and Limitations

For a complete list of outstanding run-time problems and to submit any problem you may find while running this version of Geant4, please refer to the Geant4 Problem Reporting System.


7. Compilation Warnings

There may be a few compilation warnings on some platforms. We do not believe that any of these lead to incorrect run-time behaviour.
