Alpha 3 version requires drupal_session_commit() ?

I just tried to update my Session 443 module from 6.x-1.x-dev to 6.x-1.0-alpha3. Once did this, I was unable to access the site when it was http - I could only access the site when it was https. Is there documentation on what I need to change to go from dev to alpha?

The error it's throwing is:

mod_fcgid: stderr: PHP Fatal error: Call to undefined function drupal_session_commit() in /www/virtual/newtactics.org/drupal/sites/newtactics.org/modules/session443/session443.module on line 185

drupal_session_commit() is only available in Drupal 7. ( http://api.drupal.org/api/drupal/includes--session.inc/function/drupal_s... )

Thanks for your help!
