On the 5th of October we’ll be ending our beta of Mercurial imports in Launchpad. On that day your existing Mercurial imports will cease and you won’t be able to create new ones.
This doesn’t affect Bazaar, Git, Subversion or CVS imports.
You’re probably wondering why. During the beta, we found that not many people wanted to import Mercurial branches into Launchpad. Today there are only around forty people using the facility. It’s also fair to say that our importer wasn’t of the quality we want for Launchpad.
So, with low demand for the feature we decided to focus engineering effort elsewhere rather than continue to maintain, or fix up, a less than satisfactory feature.
I’m sorry if you currently rely on Launchpad to import code from Mercurial into Bazaar. You can, though, still use the bzr-hg plugin locally.
