Hockeypuck 1.0 is deprecated and available here for archival purposes only. New installations of 1.0 are not recommended. Upgrading to 2.0 is strongly recommended as soon as a migration path is available (this is a work in progress).
The 1.0.1 branch still contains the Hockeypuck 1.x source tree.
Older binary releases are available on Launchpad.
