I just migrated a small application (~100 classes) from Wicket 7.5.0 to Wicket 8.0.0-M2. The migration itself worked flawlessly.
The only thing that I missed in the migration guide (https://cwiki.apache.org/confluence/display/WICKET/Migration+to+Wicket+8.0) was a hint that AbstractReadOnlyModel is now deprecated. (Not really a problem after reading the JavaDoc but for the sake of completeness I thought I will mention it.) Have a nice weekend, Joachim
