Redmine

• new version status "archive"
• custom field version without "archived" versions in list

Example
Every bug does not only have a target version (to be fixed) but one or many (multiple selection) "occours in version". We created a custom version field for this but have a big usablity problem.

The field drop down list growths over time so the user has to select from all versions ever created. Bugs shall be assignable to open,locked and closed version but not all closed version are still in production and shall be reported on. (e.g end of life)
There shall be a third state called "archive" what says the version was closed and is too old now for some form selection like the custom field drop down.
