Enhancement: Added WordPress Comment Spam Protection: Extended the plugin’s capabilities beyond Contact Form 7 to actively protect native WordPress comments against spam.
Enhancement: Added Regex support for spam filtering: You can now use Regular Expressions in your filters, providing advanced and highly flexible rules to catch complex spam patterns. (thanks to @jackrus60 for suggesting it)
Enhancement: Introduced custom Wordlists: Administrators can now define specific keywords to filter, giving more granular control over blocked form submissions.
Security: Improved email header sanitization: Automatically strip newline characters from email headers to prevent Email Header Injection vulnerabilities.
Security: Enhanced overall plugin security with stricter sanitization, validation, and capability checks across the codebase.
Enhancement: Flamingo integration improvements: Enhanced the email resending functionality to ensure better reliability and smoother recovery of false positives.
Enhancement: CF7 SMTP Integration: Added seamless compatibility with SMTP configurations for Contact Form 7, ensuring reliable email delivery.
Fix: Improved action detection: Fixed issues with form submission detection to ensure spam checks are consistently and accurately triggered across various CF7 setups. Also fixes an issue with Flamingo plugin actions (thanks to @jackrus60 for suggesting it)
Fix: Ensure ban reasons are properly formatted: Addressed a bug in cf7a_compress_array to guarantee that logs accurately display the specific reason for rejection.
Fix: Resolved iframe/sandbox restrictions: Added the allow-scripts sandbox attribute to ensure necessary scripts can execute properly in restricted preview environments. (thanks to @oceandigitals for reporting it)
Fix: Restricted widget visibility: Ensured dashboard widgets are now correctly restricted and only visible to users with the appropriate permissions. (thanks to @islp for reporting it)
Enhancement: General code consolidation and major refactoring of the core anti-spam engine for better performance and maintainability.
0.7.4
Fix: Improve message sanitization: handle arrays, skip empty/non-string values, and refine length checks (thanks to @sleepygoth for reporting it)
0.7.3
Fix: Dismissing the “Flamingo Message” notice now works correctly (thanks to @WORX Developer for reporting it)
Enhancement: Improved spam filter performance with additional fallbacks for edge cases
Security: Email strings are now properly sanitized before being sent
Enhancement: New dashboard empty-state view
Enhancement: Added JS selector for allowed/disallowed countries and languages
Typo: Replaced “blacklist” with “blocklist” and “whitelist” with “allowlist” (thanks to @WORX Developer for waning me about this mistake)
Enhancement: New summary table added at the top of the settings page to display form configuration status
Enhancement: Cache compatibility improvements
Enhancement: Removed UCEPROTECT from predefined blocklists: We have optimized the default DNSBL configuration by removing the uceprotect service. This strategic change reduces the risk of false positives for legitimate users hosted on shared environments and improves the overall form submission speed by eliminating redundant DNS queries.
Fix: Fix cf7a_ban_by_ip reason parameter: Addressed a bug where the ban reason was not correctly passed to the blocking function. Logs will now accurately reflect the specific trigger (e.g., Honeypot violation, DNSBL match) that caused an IP ban, restoring full observability for administrators (Thanks to @sdellenb – PR #163).
Compatibility: Implemented a fix for WEBGL_debug_renderer_info in iOS/Safari on newer iOS devices. This resolves potential JavaScript execution errors during browser fingerprinting, ensuring seamless form functionality on iPhones and iPads with strict privacy settings.
Enhancement: Added blueprint.json: Introduced a configuration file for WordPress Playground. Contributors and users can now instantly spin up a browser-based testing environment for the plugin without local setup.
Enhancement: Updated unit tests to display GeoIP database information if available. This enhances local debugging capabilities by verifying that geolocation data is loaded correctly during test runs.
Enhancement: Applied comprehensive PHP linting to the Admin interface files, enforcing WordPress Coding Standards for better maintainability.

Fix: Refactored and reorganized the src folder structure for better code organization and maintainability.
Fix: Implemented REST API endpoints for the admin “Tools” section, allowing operations on that page to be performed without reloading.
