This release mainly contains significant performance improvements. In particular, kernel.terminate events are no longer executed for fresh cache entries. Previously, these events caused e.g. the search index to always be updated, even though the entry came from the cache. Consequently, a database connection was also established for a cache hit. In addition, the search indexer was adjusted so that it now correctly considers "noindex". Furthermore, the number of database queries was significantly reduced to further minimize the load on the server. Apart from the performance improvements, a nice error message is now displayed if restoring a version fails and the order of video formats has been changed so that webm is now loaded before mp4 to choose the more efficient format if the browser supports it.
