    - Fixed documentation error in synopsis for QR codes.

    - Fixed date validation when timezone offset minute contains a trailing
      apostrophe, which is required by the Adobe PDF specifications and
      prohibited by the ISO PDF specifications.  PDF::API2 now accepts either
      version as valid (report by Johan Vromans).

    - Fixed passing a GD object to $pdf->image() (reported by Hakon Hagland).

    - Fixed a crash when object numbers contain leading zeroes.
