This has already happen yesterday, but I decided to announce it today, because now there is snapshot with all those changes.
With Subversion we can rename files without losing their histrory and
this possibility lead to huge cleanup of file names. I dropped all
_properties parts of table and database pages. As user
you should not notice anything (except for different URL), but there
might be still some problematic parts which has not been detected when I
did this change.
So please give a current trunk snapshot or demo a bit of testing so that we can find problems before going to RC stage.
