This release introduces several enhancements and fixes across the system. Search functionality has been improved with the addition of listeners for news, events, and FAQs that will now delete a previously stored search index entry when switching to noindex. The user interface sees multiple improvements, including a refined back end layout for mobile devices, unified .cte_preview styles for consistency, and a fixed Dropzone overlay in the file tree. Additionally, more irrelevant query parameters are now stripped from URLs, resulting in more HTTP cache hits out-of-the-box.
