There is no regression. The behavior is normal. If there is no
svn:mime-type property, then Subversion thinks it's a text file. When
you add a file, Subversion briefly analyzes the file and guesses
whether it is text or binary. If Subversion guesses that a file is
binary, it sets svn:mime-type to application/octet-stream; if it
guesses a file is text, it does nothing. For PDF files, Subversion
often incorrectly guesses that they are text (because the PDF format
is rather texty) and therefore does not add the svn:mime-type
property. If you would like Subversion to add the svn:mime-type
property for PDF files, set up auto-props on your client. application/
pdf would be a good value to use for PDF files.
