The AMO team is finalizing the latest update, 3.4.1. This is a bug-fix release addressing things like double escaping, improper L10n redirects, and category cleanup. A list of all the bugs targeted for this release is available.
We’ll be committing the last of the patches very shortly and the changes will be available on preview.addons.mozilla.org. Feel free to look at the changes and send us any feedback you have. We expect to push the changes live this Thursday evening (May 1st).
Our next release, 3.4.2, is currently scheduled for May 15th. 3.4.2 will also be a bug-fix release – there are currently 19 candidates.
