Based on this strong positive response and adoption during the beta, we're officially moving SSL Endpoint to general availability starting today. It is now the recommended option for any app which needs SSL on a custom domain.
In conjunction with SSL Endpoint's GA status, we're consolidating and simplifying our SSL product lineup by deprecating all of the older SSL add-ons: SNI, Hostname SSL, and IP SSL. SSL Endpoint is easier to use, more robust, faster to provision, and offers more features (such as certificate rollback and client IP address as an HTTP header).
Beginning June 18, 2012, these other SSL add-ons will no longer be provisionable via
heroku addons:add. Applications that already have these add-ons installed will continue to function normally, and we'll continue to fully support the SSL capabilities for those apps on an ongoing basis.
