Decryption key:
New: WP Cerber continuously monitors IP detection issues and provides diagnostic messages. If IP detection fails due to configuration or server settings, the details of the issue are displayed to assist in troubleshooting.
Improved: When valid proxy headers are missing, WP Cerber falls back to the standard $_SERVER['REMOTE_ADDR'] variable to extract IP addresses.
Improved: If the PHP constant [CERBER_IP_KEY](https://wpcerber.com/wordpress-ip-address-detection/) is configured but does not provide valid IP address, WP Cerber switches to fallback methods for IP detection.
Improved: The Sessions page now marks users with enforced [2FA](https://wpcerber.com/two-factor-authentication-for-wordpress/) using a green "2FA" label. A solid label indicates successful verification, while an outlined one means verification is pending.
Improved: WP Cerber’s cookies in the "Live Traffic" log are highlighted in green under "Server Response Cookies". Their values are now properly decoded for easier analysis.
Improved: REGEX patterns for [URL exceptions](https://wpcerber.com/antispam-exception-for-specific-http-request/) no longer require escaped slashes. Existing patterns are automatically updated during the upgrade.
Improved: 2FA PIN emails now include the recipient’s first and last name along with their email address. This change helps improve email deliverability.
Improved: Enhanced storage of 2FA session data prevents its misuse as an attack vector in compromised WordPress databases.
Improved: 2FA login forms have been improved for full compatibility with WordPress installations in sub-folders, particularly on web servers with sub-optimal configurations.
Improved: Database operations are optimized to leverage the latest PHP-compatible technologies. Performance on modern servers is improved.
