Is Redmine Version 2.2 canceld?
It suddenly disappeared from roadmap and therre is now news or svn tag for release.
Tx for imformation.
This is the default behavior for Redmine. It hides all completed Versions. And since all tickets are closed and the due-date was reached, the Milestone doesn't show up. Just tick "show completed versions" and you got it back. And I think the announcement will come. And consider the time of the year ;)
