ads.txt 8.x-1.5 Drupal 12 compatibility. - Fixed a fatal error that broke installing any module while ads.txt was enabled on Drupal 11.3 and later. hook_requirements() is now implemented as hook_runtime_requirements(), with the procedural version marked #[LegacyRequirementsHook] for older core. - Fixed /ads.txt and /app-ads.txt returning a permanently cached 404 once the content had been empty. The 404 is now returned as a cacheable response so it is invalidated when content is saved. - Added the return types required by Drupal 12 deprecation notices. - Dropped Drupal 9 support, which was broken and end of life. Supported core: ^10.2 || ^11.0 || ^12
