Finally tagged after many years as dev-only, this is the first release for Drupal 6 / Pressflow 6, hopefully to also become the final release for these platforms.
All users should use it instead of the -dev version until a RC is released.
Minor bugs were addressed
First release for 6.x-2.x, no further features are planned.
Switched to use CURL in Drupal 6.
Added the ability to specify SSL vertify_peer and a valid crt file in the settings. Check the README.md file for more details
