• SECURITY: Fixed a cross-site scripting vulnerability in the code that updates the Required Membership settings on a post. This vulnerability could have been used in conjunction with other security vulnerabilities to trick an admin into editing the membership settings for a page, potentially exposing members only content to non-members. It is unlikely that there was any active exploitation of this vulnerability. This issue may also have shown up as a bug on some sites using page builders, where the membership settings for a post would be cleared out when editing a post. (Thanks to the wp.org plugin review team for catching this issue.)
• SECURITY: Better escaping of variables shown in the Require Membership meta box and related SQL queries.
• BUG FIX/ENHANCEMENT: Renamed the Vietnamese language files to match what is expected.
