We probably would have had a teaser or two by now but not literal update trailers with the version number and even one with "insert devblog link here".
Summer vacations, would they release update during those or when full staff available? Maybe teasing to create interest during summer sale. Sure it would be nice to have update before August, but it would be quite exceptional, imo.
Just checked, yep it is a real image on the documentation. its on the userfolder tab in the support section
Imo the update is coming Tuesday because if it was not they wouldn't have made the Traffic Light video for 0.23 on June 22th saying that the feature is still only gonna be available on ECUSA.
