  1. Subscribe2 10.48Latest

    • Fix: Stored Cross-Site Scripting in the Subscribers list table. The signup IP address recorded for public subscribers was rendered unescaped, allowing content stored through the AJAX subscription form (available when the popup style subscription form is enabled) to execute in an administrator’s bro…

Sending a preview now requires permission to edit the specific post, resending a notification requires the same capability as the Send Email screen (manage_options, filterable through s2_capability) in addition to permission to edit the…
    • Fix: Block editor email preview always used the digest branch because the plugin options were read from an undefined property, which also caused an “Undefined array key” warning during preview.

    • Fix: PHP 8.2 “creation of dynamic property” deprecation notices by declaring previously undeclared class properties.
    • Fix: PHP 8.1+ “passing null” deprecation notices when building notification emails.

  3. Subscribe2 10.46
