🌿 The Spring Update

Release Date: March 24, 2026

✨ New Feature

  • Exclusions by Filesize: You can now exclude images from optimization based on their file size, giving you even more precise control over what gets processed.

🛠️ Fixes

  • Bulk Operation Messaging: When running bulk actions other than optimization, the correct descriptive text is now displayed.
  • PICTURE Tag Fixes:
    • Fixed issues with certain background images not being handled correctly.
    • Multiple improvements to ensure correct paths and compatibility with Bedrock setups.
  • Long Domain Handling: Fixed cases where very long domains caused CDN URL replacement to fail.
  • Invalid API Key Feedback: A proper message is now shown in the AI settings preview when an invalid API key is used.
  • AI Disabled Notice Scope: "AI generation disabled" message now appears only in the settings preview to avoid conflicts (especially with the Classic Editor).
  • Async Chatbot Loading: The chatbot now loads asynchronously in settings to prevent slowdowns when CDN responses are delayed.
  • JS Worker Stability: The JavaScript worker no longer stops if invalid JSON is received from the backend.
  • LS Cache Compatibility: Fixed incompatibilities with LiteSpeed Cache and certain custom media folder setups.
  • Custom Media Errors: Resolved errors occurring during optimization of specific custom media folders.
  • open_basedir Improvements: Additional safeguards to prevent warnings with strict open_basedir configurations.
  • PHP 8.4 Deprecation Fix: Fixed a rare deprecation warning on PHP 8.4.

🛡️ Security Fixes

  • PHP Object Injection: Patched a potential vulnerability related to AI-generated SEO data (reported by PatchStack).
  • Stored XSS (Author+): Fixed an authenticated stored XSS vulnerability when using AI features (reported by WordFence).

✨ Tweaks & Improvements

  • Wording & Layout Updates: Small improvements to texts and settings layout for a cleaner and clearer experience.

Update now for stronger security, improved compatibility, and smarter control over your optimization workflows! 🚀
