Not substantially, no. The v3.0 release does include a ton of new features, as everyone will find out in a very short while, but the core focus for v3 was a change in architecture that will open up a lot of new options for us in v3 and up, vs. the v2.x design. (v3.0 is a standalone software package, and doesn't depend on any pre-existing software on your machine such as Apache/etc.)
That said, we'll be making some minor improvements to the playlist scheduling system in the v3.0 series, and some major ones in the v3.1 release, and your request here is among them.
