The JIRA Importers Plugin 2.2 has been released and adds support for Pivotal Tracker!

It's in a very alpha stage at the moment, but should work in most cases. All you need to do is give it your Pivotal Tracker username/password and it will take care of the rest. If you have a Pivotal Tracker account please give it a go and let us know what you think!

Other highlights of the 2.2 release:

1. CSV importer can create attachments when pointed to a URL
2. Improved UI when dealing with projects which already exist
3. Better behaviour for large scale imports (thousands of issues)
4. Many fixes for Mantis, Bugzilla and CSV importers

To use the new importer you will need to have JIRA 4.3 or above. Download the latest JIRA release and install the latest importer plugin via the UPM - just search for 'importers'.
