I downloaded all provided by Feedback Release Notes, then I placed them into a home made application and saw that 2008r1 is 1 line long (one entry). This cant be so, so I checked on my Xojo, Real Studio, REALbasic archives and get the original 2008r1 Release Notes and they have far more entries.
As stupid as I am, I wrote a simple bug report trying to tell just that and get a strange answer: we will not remove a bug on a so older release" (something like that).
Errare humanum est, perseverare diabolicum. I forgot that and I perseverare. I issued another bug report and I get another strange answer: with current Xojo Feedback application, only 2009r1 and earlier Release Note should be displayed (something like that).
So, using Feedback 2014r1 (Cocoa), I can see:
Now, we all can see the limits of Feedback and good will (sometimes).
This is one of the reasons I am a bit reductant to send bug reports.
Other reasons are in these answers (uncomplete list): Closed (By Design) and Not a bug.
