+## CHANGES IN V2.0rc1 (11th April 2023)
+
+- PPD file generator: Set default color mode when printer attrs say "auto"
+  Actual printer default color mode did not get set and the often "Gray"
+  gots set for color printers. No we always choode the "best" mode.
+
+      https://bugs.launchpad.net/bugs/2014976
+
+- ppdLoadAttributes(): Find default page size also by dimensions
+  Some PPDs can contain the same page size twice with different names,
+  whereas the PWG cache created from the PPD contains each size only
+  once. This could make the default size not being found when the
+  PPD is converted to IPP attributes. Now we search also by size and
+  not only by name.
+
+      https://bugs.launchpad.net/bugs/2013131
+
+- PPD generator for driverless printers: Add "*LandscapeOrientation:"
+  according to the landscape-orientation-requested-preferred printer
+  IPP attribute.
+
+- ppdFilterLoadPPD(): Corrected PPD attribute name so that for printers
+  which receive PWG Raster a sample Raster header gets created.
+
+- Make the testppdfile utility getting built and installed by default
+
+- Improved formatting of reports generated by ppdTest()
+
