    Released 3.4.5

Changes since the last tag '3.4.4':

Robert Ancell (8):
      Add support for the Samsung Unified Driver (SUD) which enables ADF Duplex and correct colour     mode 
selection. Note that SUD's document source is not the standard SANE NAME_SCAN_SOURCE so     the SUD-specific 
"doc-source" is queried if the SANE "source" fails to find an option.
      Add non-standard option names for duplex scanning on HP And Brother scanners
      Use new GLib threading API
      Hide C warnings, compile with Vala debugging information
      Don't access a variable after ownership is transferred - was breaking scans
      Set scan area of br-x and br-y to page size - this fixes drivers that don't have page-width and 
page-height options
      Stop configure if vala not found
      Releasing 3.4.5
