This is pretty unusual.

Actually, people do a service by installing and testing pre-release 
software.  They just need to realize that this is what they are doing 
;-). There was a bug in 3.4.0, I believe it was, that was caught on the 
second day when someone installed and ran the test suite of their 
software.  It would have nicer if that testing had been done sooner.
