Only show needed Versions
When my customers report a new issue, they get a pull down with the 'target version'. Can you limit this list to active versions. Say I've released v1 of the project, I want the customer to not be bothered with the v1 in that list anymore.
If you want people to report against released versions, I suggest we add a checkbox to the settings->versions page, where you can indicate that the version is not open for bugs or maybe even call it 'closed'.
