Changelog

1.3.5

Fixed: settings page hook suffixes were calculated manually and didn’t match the real hook suffixes generated by WordPress (which derive from the top-level menu_title, not the menu slug), causing CSS/JS to fail to load on Bulk Optimization, Statistics and Diagnostics pages
Fixed: admin styles/scripts now use the real hook_suffix returned by add_menu_page()/add_submenu_page() instead of a hardcoded guess
Fixed: media library “Optimize” button (upload.php/post.php) registered its own style/script handle instead of relying on a handle that wasn’t enqueued on those screens
Fixed: synced plugin version number across the main file header, the NIQUELAO_VERSION constant and readme.txt Stable tag
Fixed: missing i18n wrapper on one bulk-optimization status string

1.3.2

Unified license to GPL-2.0-or-later across all files
Added full internationalization (i18n) via () and esc_html() functions
