Alexandre,
The profile plugins are still all in the component zip file. Unzip it, and you'll find them all in /admin/install/packages/socialprofiles. We understand it'd be nice in limited cases to have them automatically installed, but we've had very good feedback that we aren't installing completely unusable plugins on sites as well. It's a balance we've had to strike between the previous "you install everything manually and tediously" and installing everything automatically.
As for the updates to the socialprofiles, we agree, it's changing a lot recently. Most of that is to support new network providers as easily as possible. Things are stabilizing, and we are planning better developer documentation later this year (after the v5.2/Twitter release comes out in early November). The v5.2 release will also have 2 new plugins that will be always installed:
* CustomDB - This will let you set a database table on your site to store profile information into. You may be able to use this plugin (depending on your needs) without modifying code at all.
* Joomla - This enables integration with the User - Profile plugin from Joomla. It's not the greatest profile system, but we had a decent amount of requests to support it.
The JFBConnectProfileLibrary::getInstance() error is a bug. We added backward compatibility to the v5.1 release, but it's not perfect, as you can see. The easiest way to fix that code, though, is to update it to:
$profileLibrary = JFBCFactory::provider('facebook')->profile;The nice thing is that that works for 'facebook' or 'google' or 'twitter' (soon). That's the cause of a lot of changes is to simplify things like that, but it's causing a little bit of rough edges during the transition from Facebook-only to all social networks, and I apologize for that.
The good news is that there are many fewer changes in the 5.2 release. The biggest you'll run into, just to warn you, is the move to config.xml (JForm) files for the configuration options in the Social Profile plugins. It makes add/changing options much easier, but you'd need to create that XML file first to use it.
I hope that helps explain, but as always, feedback is welcome.
Thanks,
Alex
