Although I find myself unable to notice the changes in this year's conbook simply due to the fact that this was my first Eurofurence, I found it to be rather enjoyable reading and quite useful at the same time.
For somebody who was new to the con, the timetable along with the event descriptions provided a good overview of the variety of panels and other activities throughout the EF, which was supplemented really well with updates made available via the EF-App, which in turn could easily be accessed along with the public WiFi via the 2D barcodes in the conbook.
The commercials mentioned by Dhary were imho few and well integrated and selected enough to not be annoying or distracting from the more important parts of the conbook in any way.
Since they also help to pay for the printing costs of those beautifully colourful, informative and entertaining pages, I think they can easily be tolerated, especially since they are rather unobtrusive (as opposed to those in various other publications I know) and mainly advertise other furry conventions and some other furry things.
One thing, which might have been useful for those who were not privy to the Android/iOS app, would've probably been an additional insert detailling the car parks along with their daily rates around the venue (maybe even along with a little map or integrated into the one on the "show-your-badge" pamphlet).
I for my part am really grateful for all the hard work you guys put into creating this conbook, which was really helpful to me right from the start!
Keep up the good work! :3
Addendum:
Since I apparently took too much time before actually submitting this post, I can also only second what Kisu wrote! (-;
