This update does not bring new features as there will be a much larger update coming very soon. This does, however, improve the codebase and make error logging significantly better—making support faster, easier, and more accurate.
So, I would still recommend this update for all customers.
You can now import Steam data from HowIChrgeLazer's Steam authentication for XenForo 1.
Added the ability to prevent non-Steam registration. This both hides the standard registration fields and social buttons along with completely preventing the standard registration code from running.
Associations and dissociations are now logged in the admin panel.
The Steam button has had some styling applied to it. Now, it includes the Steam icon.
Before installing XenForo 2, do NOT uninstall your XenForo 1 Steam integration. You can disable it if you wish. But, doing a complete uninstall will delete the necessary data from the XenForo 1 database.
Next, go ahead and upgrade to XenForo 2. And, once you install our add-on, it should automatically migrate your existing users to the new system. After that, you can go ahead and uninstall your old add-on.
Note: Please make sure you backup your data prior to running any upgrades - official or otherwise.
