s2Member v240325 (Framework and Pro) was released on March 25th, 2023.
Unified Changelog for s2Member & s2Member Pro v240325
(Framework) Fix: Some sites were getting a warning from v240315's restriction improvement when the WP REST request doesn't include a type or ID. Fixed in this release. See thread 11347
(Pro) Enhancement: Checkout success redirection URLs are now validated as safe with WordPress' wp_validate_redirect. To use a domain different than the site's, it can be allowed with wp's filter allowed_redirect_hosts.
(Framework) Enhancement: Additional validation to prevent an invalid s2Member Level role during registration.
