In this release, further optimizations have been made to the new HTML filter. Now not only PNG/JPEG to WebP but also vice versa WebP can be automatically converted to PNG/JPEG (if the server supports this). The HttpCache can now be deactivated via an ENV variable and the backend can no longer be called by mistake via the front end preview.
