1.0.7

• Database Optimization: Replaced slow NOT EXISTS and empty string database operations for the Alt Text filter with a high-performance indexed flag (_levelnetwork_mlf_has_alt). Drastically improves response times on Enterprise websites with large media libraries (50k+ items).
• UX Fix: Optimized the “Reset Filters” action in Grid View. Combined multiple sequential Backbone model updates into a single event loop to prevent duplicate, concurrent AJAX requests to the server.
• Code Quality & Compliance: Standardized uninstall.php to use native WordPress functions (delete_post_meta_by_key), ensuring full synchronization with object caching systems (Redis, Memcached) and complete cleanup of global plugin options upon deletion. Resolved WPCS global variable scoping warnings.

1.0.6

• Initial release.
