I'm always excited to see that yellow "A new version is available - click here!" box, and to see what the new elements do. It seems there used to have been updates about once a week, but now it's been at least a month I think and there hasn't been one. Is there any particular reason for this? I know the developers have other things to do, but I'm just asking.

That is because some elements needed small modifications. Now only new elements will come out.If they have problems there will be many updates. And stop asking.
