Changelog
1.6.0
- Fixed: the setup wizard never stored the API key. The settings sanitizer also ran for saves made outside a settings form and threw those values away, so neither “Verify” nor “Save & Continue” nor “Skip Setup” persisted anything. Verifying now saves the key immediately, and skipping saves whatever was typed.
- Fixed: saving the settings page with an empty API key field no longer erases the stored key. The field is no longer pre-filled with the secret, an empty value means “unchanged”, and removing the key now needs an explicit checkbox.
- Fixed: saving the API Configuration form no longer resets every llms.txt setting and clears its scheduled regeneration. The two forms now use separate option groups, so saving one can never touch the other.
- The wizard no longer claims “Connection verified!” for what is only a format check. Test the real connection from your SEMUST dashboard.
- Added heading level fixer: locate a heading in page content and change only its level, from the Technical SEO audit.
- Only headings that live in page/article content are editable. Headings generated by the theme, comment form or Table of Contents widgets are reported as general structure and left alone.
- Byte-level safety checks, read-back verification and automatic rollback: the change is refused unless nothing but the heading level digit differs.
- /info now reports plugin capabilities so the dashboard can hide features this install cannot perform.
- Requires WordPress 6.0 for the heading fixer. Every other feature still works on WordPress 5.0.
1.5.1
- Fixed API key being cleared when saving llms.txt settings.
- Fixed the wizard generate button.
- Turkish translation for the auto-update text.
- Added SEOPress, The SEO Framework, Slim SEO and SmartCrawl support.
1.5.0
- Meta-only updates no longer wipe post content.
- Update response now returns the detected SEO plugin for clearer error handling.
1.4.2
- Fixed 403 permission denied on post updates via the API.
1.4.1
- Fixed empty llms.txt: added a database fallback when the homepage HTTP crawl fails.
1.4.0
- Added the llms.txt generator with an enable/disable toggle, database and sitemap URL discovery, SEO description extraction, batch processing with a progress bar, an auto-update schedule and a persistent generation log.
