Roughly every four weeks, we release a new milestone version of Launchpad with the latest features and bug fixes.
Launchpad milestones are an easy way to target blueprints and bugs to a release on a particular date. For example: on 20 June 2007 we released milestone 1.1.7.
You can see what we have planned for each Launchpad application by visiting the milestone page for the application that interests you. The milestone pages for each Launchpad application are linked from the Launchpad project overview page.
