Hi and thanks for maintaining this library.

I recently started working on Drupal site that uses https://www.drupal.org/project/hybridauth and with this library, Hybridauth 2.x. I's been a while since last release of 2.x and in the mean time PHP releases new versions, servers get updated, there is an increased focus on security:

• What is the current state to the 2.x branch? Is it supported or EOL? README.md state it is maintained?
• What is the highest version of PHP 2.x works with/on?

Best reg.
