This is the first stable release of the 7.x-1.x branch of the Statuses module, formerly known as Facebook-style Statuses. Continue referring to the FBSS documentation until #1685446: Port documentation to D7 is fixed; this release is a straight port from the 6.x-3.x branch of FBSS.
Roadmap
The steps to get to a full stable release of Statuses are outlined at #1551542: [META] Release Plan. The remaining known issues should not significantly affect a majority of sites, but check to make sure you will not be affected before upgrading from Drupal 6. If you would like to help us get to a stable release, posting patches for the issues in the release plan is the best place to start.
Upgrade Notes from 7.x-1.0-unstable4
A couple of integrations were removed (see section below) -- but since they weren't working in the previous 7.x-1.x releases, if you were using 7.x-1.0-unstable4 this probably doesn't affect you.
Upgrade Notes from 6.x-3.x
Before you start, please note that the name change from "facebook_status" to "statuses" complicates the upgrade path. We've automated most of it, but please back up your database before upgrading and, if you can, test the upgrade on a development instance before upgrading production.
