    154159== Changelog ==
     160
     161= 3.2.0 =
     162
     163- Feature: You can use the option “Images only” to disable features for non-images in the media library, e.g., PDF files
     164- Improvement: When authors change content, ISC now looks for removed or new images at the next visit of that page in the frontend. This highly improved compatibility with page builders and dynamic content like shortcodes.
     165- Improvement: When WP_DEBUG is enabled, show a button to list the content of the internal storage on the Tools page
     166- Improvement: Removes image source output on pages with the Global List on it
     167- Improvement (Pro): Ignores image URLs in `href` attributes when looking for image sources
     168- Improvement (Pro): Clears the URL storage when the Indexer runs. This can help with issues when a site was migrated to another URL
     169- Improvement (Pro): Extends ignored options for unused images
     170- Improvement (Pro): The column with image sources forms in the Media Library list view only shows if the user has the permission to edit any image information
     171- Improvement (Pro): The forms to edit image sources in the Media Library list view only show if the user has the permission to edit information for that given image
     172- Improvement (Pro): The Indexer for Unused Images now works with posts translated by WPML
     173- Fix: Removes old index information when the last image in a post is removed
     174- Fix (Pro): Some reserved characters in URLs caused (e.g., `&`) the bulk edit fields for images sources in the media library to be cut off
     175- Dev: Extracts post meta handling (`isc_image_posts`, `isc_post_images`) into dedicated classes.
     176- Dev (Pro): Disable image source form fields in the Media Library list view when submitting the filter form to prevent broken URLs. This is related to a compatibility issue caused by a third-party setup
     177- Dev (Pro): The Indexer now works in batches to prevent timeouts on large sites when Query Monitor is installed
     178- Dev (Pro): Pages with the Global List shortcode are now ignored by the Indexer.
     179- Dev: Adds cleanup routines for meta data for deleted and trashed posts.
     180- Dev: Replace some direct DB calls with WP functions
     181- Updates German translation

    154159== Changelog ==
     160
     161= 3.2.0 =
     162
     163- Feature: You can use the option “Images only” to disable features for non-images in the media library, e.g., PDF files
     164- Improvement: When authors change content, ISC now looks for removed or new images at the next visit of that page in the frontend. This highly improved compatibility with page builders and dynamic content like shortcodes.
     165- Improvement: When WP_DEBUG is enabled, show a button to list the content of the internal storage on the Tools page
     166- Improvement: Removes image source output on pages with the Global List on it
     167- Improvement (Pro): Ignores image URLs in `href` attributes when looking for image sources
     168- Improvement (Pro): Clears the URL storage when the Indexer runs. This can help with issues when a site was migrated to another URL
     169- Improvement (Pro): Extends ignored options for unused images
     170- Improvement (Pro): The column with image sources forms in the Media Library list view only shows if the user has the permission to edit any image information
     171- Improvement (Pro): The forms to edit image sources in the Media Library list view only show if the user has the permission to edit information for that given image
     172- Improvement (Pro): The Indexer for Unused Images now works with posts translated by WPML
     173- Fix: Removes old index information when the last image in a post is removed
     174- Fix (Pro): Some reserved characters in URLs caused (e.g., `&`) the bulk edit fields for images sources in the media library to be cut off
     175- Dev: Extracts post meta handling (`isc_image_posts`, `isc_post_images`) into dedicated classes.
     176- Dev (Pro): Disable image source form fields in the Media Library list view when submitting the filter form to prevent broken URLs. This is related to a compatibility issue caused by a third-party setup
     177- Dev (Pro): The Indexer now works in batches to prevent timeouts on large sites when Query Monitor is installed
     178- Dev (Pro): Pages with the Global List shortcode are now ignored by the Indexer.
     179- Dev: Adds cleanup routines for meta data for deleted and trashed posts.
     180- Dev: Replace some direct DB calls with WP functions
     181- Updates German translation
