Version 2.0 is now the "lowest" version that can be downloaded from APT repository at the moment. Even though the "full backward compatibility" of Jenkins 2.0 is advertised - we have found the case when it's not. The software vendor I work with uses jenkins internally from cronjob management (only on local network). Version 2.0 by default requires authentication setup, which breaks the application. As the lifecycle of their releases is pretty long, I would be very happy to be able to stick to "older" version, but sadly - it's not available in repository anymore.
It is generally a very good practice to allow people to download all older versions and not force them to use the latest one. Would that be considered at Jenkins, or do we have to fall back to non-elegant methods like repository mirror with v.1.652 ?
