There shall normally be no less than two releases per calendar year and no more than four.
The approximate release date shall be announced (to HEPLIB and in the CERN news groups) at least two months in advance.
The approximate content shall be discussed and agreed at least one month in advance.
The exact content shall be discussed and agreed at least two weeks in advance.
The final versions of the various packages should be made available to the CERN Program Library team to permit installation in the public NEW area together with an appropriate announcement in the HEPLIB news group at least one week prior to the announced release date.
In the case of minor last minute corrections uncovered during user testing, the final code should be delivered at least one working day prior to the release.
In the event that such a deadline cannot be met, the CERN Program Librarian may decide to delay the release or to revert to a previous version of the package.
