CiviCRM Stripe
ayment Processor integration for Stripe ( into CiviCRM ( I
built this right as CiviCRM 4.2 was coming out, which changed many things about how CiviCRM extensions were
made (new features, not backwards compatible), so I released 3 versions of this, instead of just the 1 the client
requested (4.1). I made a 3.4 - 4.1 version, 4.2, as well as packaging the 'source' version for any version. Over
50 actively using this since August 21st!
