  • ### Added:
  • WP-CLI commands to configure WP Mail SMTP from the command line, including SMTP and API-key mailer setup, individual setting management, and alert provider configuration.
  • Code Snippets tab on the Tools page to browse, preview, and install WP Mail SMTP's WPCode snippets.
  • Support for the WordPress Abilities API (WordPress 6.9), letting connected tools and AI assistants securely read your email logs, sending statistics, and debug events.
  • Your Pro license now activates automatically after installing the plugin.
  • A one-click option to deactivate a conflicting plugin directly from the conflict notice.
  • Confirmation prompt before enabling the "Hide Email Delivery Errors" option, so the setting is not turned on by accident.
  • ### Changed:
  • ### Fixed:
  • The WPMS_LOG_BLOCKED_EMAILS constant in wp-config.php did not affect the Log Blocked Emails setting; defining the constant now correctly enforces the value, disables the option in the admin area, and shows a notice indicating it is set by a constant.
  • AWS SES mailer triggered a PHP `is_readable()` warning when reading AWS config files on servers with an `open_basedir` restriction.
  • Failed email alerts linked to the wrong Email Log entry when a backup mailer succeeded after the primary failed; the alert now links to the failed primary's Email Log entry instead of the backup's success entry.
  • Hosts using database read replicas could show duplicate Email Log entries and missing error details.
  • Alert notifications flooded scheduled actions and external channels during provider outages; automatic alerts are now limited to one notification every 5 minutes.
  • The "Last week" stat in the Lite weekly summary email showed the just-started current week's count instead of the actual previous week's total, because the email is sent on Monday at 2pm.
  • Connecting the Zoho mailer could trigger a fatal error when Zoho returned an unexpected account response.
  • Hardened permission checks and request handling across several admin and alert features to address potential security issues.
Improved
  • error handling and troubleshooting guidance when an email fails to send.
  • Action Scheduler library to 4.0.0.
