This release primarily focuses on performance improvements in the back end. Following extensive work by the core team, secondary operations are now loaded lazily when required, significantly improving the loading times of larger page, article and file structures. Combined with various JavaScript optimizations and more efficient polling for back end jobs, affected views can now load more than twice as fast as before in many cases! In addition, root-page-dependent front end modules now support content elements, providing greater flexibility when building websites.
