To contribute patches to Geant4, users can submit Pull Requests (PR) such that:
- A single PR refers to a single particular topic (fix or suggested enhancement); PRs including uncorrelated changes in codes in different areas or modules will not be considered.
A PR will be examined by a responsible and eventually extracted for a patch in the development repository of Geant4, to be included in a future release or patch.
For simple bug-fixes, it is anyhow recommended to use the official
Bugzilla problem reporting system <https://bugzilla-geant4.kek.jp/>.
