 - (s2Member/s2Member Pro) **Bug Fix:** Username/password email being sent to users whenever Custom Passwords are enabled in your s2Member configuration and registration occurs via the default `wp-login.php?action=register` form. Fixed in this release. See also: [issue #870](https://github.com/websharks/s2member/issues/870) if you'd like additional details.
 
+- (s2Member Pro) **Bug Fix:** In the `[s2Member-List /]` search box shortcode an empty `action=""` attribute produces a warning due to invalid syntax in HTML v5. Fixed in this release. See [Issue #1006](https://github.com/websharks/s2member/issues/1006)

 - (s2Member/s2Member Pro) **IP Detection:** This release improves s2Member's ability to determine the current user's IP address. s2Member now searches through `HTTP_CF_CONNECTING_IP`, `HTTP_CLIENT_IP`, `HTTP_X_FORWARDED_FOR`, `HTTP_X_FORWARDED`, `HTTP_X_CLUSTER_CLIENT_IP`, `HTTP_FORWARDED_FOR`, `HTTP_FORWARDED`, `HTTP_VIA`, and `REMOTE_ADDR` (in that order) to locate the first valid public IP address. Either IPv4 or IPv6. Among other things, this improves s2Member's compatibility with sites using CloudFlare. See also: [issue #526](https://github.com/websharks/s2member/issues/526) if you'd like additional details.
 
 - (s2Member Pro) **JSON API:** In the pro version it is now possible to use the s2Member Pro Remote Operations API to send and receive JSON input/output. This makes the Remote Operations API in s2Member compatible with a variety of scripting languages, not just PHP; i.e., prior to this release the Remote Operations API required that you always use PHP's `serialize()` and `unserialize()` functions when making API calls. The use of `serialize()` and `unserialize()` are no longer a requirement since input/output data is now sent and received in the more portable JSON format. For new code samples, please see: **Dashboard → s2Member → API / Scripting → Pro API For Remote Operations**. See also: [issue #987](https://github.com/websharks/s2member/issues/987) if you'd like additional details on this change.
