Now after 1.08 is final I need to boldly go to the next frontier...

Actually I will flash 1.09b onto my box, but before doing so I would like to ask 2 things to the community. First, are there any (visible) additional changes in this release compared to 1.08 besides the already mentioned cloud backup service?
And second point, if it isn't so, why is the binary about 750k *smaller* compared to the 1.08 final?? Sounds to me some programs and/or functions have been dropped or so? Or just an artifact because of better compression?
Thanks for any info!
