I encountered some issues booting the older kernel included in the current ISO file. For example I get issues with hibernation on my laptop (which is fixed in the newer kernel) and a friend of mine got issues with booting on NVIDIA graphics to run setup. Refreshing the ISO to contain the latest packages would help a lot of people and ensures that packages are being kept up-to-date so no one has to deal with updates on slower connections. It would be nice to make an ISO refresh when a new "roundup" blog post comes out or like on Arch every first day of the month.
