• (s2Member Pro) Bug Fix: s2's payment notification when creating a Stripe subscription, was being sent twice. Added a check to ignore the webhook for the subscription's on-session first payment; s2's webhook endpoint is for off-session events.

• (s2Member Framework) Enhancement: Added a new hook for the payment notification on subscription creation or buy now payments.

• (s2Member Pro) Bug Fix: Stripe paid trials were accumulating on failed payment attempts, causing a larger charge when it finally succeeded. Kudos to Alan for his help through the many attempts to fix this one, see post 7002

• (s2Member Pro) Enhancement: Stripe duplicate payments were happening randomly to a few site owners, apparently from bad communication between their server and Stripe's. Added idempotency to prevent duplicates. Kudos to Alan and everyone in the forum that reported and gave details on this behavior, see post 7002
