+## CHANGES IN V2.0b4 (22nd February 2023)
+
+- Transfer CUPS' `cupstestppd` utility to `ppdTest()` library function
+  The valuable tool got forgotten in the first place, now it is available
+  as `ppdTest()` library function and `testppdfile` command line utility.
+  The command line utility only gets installed with `./configure`
+  called with `--enable-testppdfile` argument.
+
+- In auto-generated PPDs do not set RGB default on mono printers
+  When a PPD for a driverless printer is generated by the
+  `ppdCreatePPDFromIPP()` function and the get-printer-attributes IPP
+  response gives "print-color-mode-default=auto" the PPD's default
+  setting for "ColorModel" is always "RGB", even on monochrome
+  printers, which makes printing fail on most devices.
+  Now we ignore the "print-color-mode-default" if set to "auto".
+
+  See https://github.com/OpenPrinting/cups/issues/614
+
+- ppdLoadAttributes(): Added NULL check for missing PPD PageSize default
+  Some PPDs, even "everywhere" PPDs generated by CUPS for a driverless
+  IPP printer do not have a valid default value for the default page
+  size, like "Unknown". Added a NULL check to avoid a crash by such
+  PPD files.
+
+- Coverity check done by Zdenek Dohnal for the inclusion of libppd
+  in Fedora and Red Hat. Zdenek has fixed all the issues: Missing free(),
+  potential string overflows, ... Thanks a lot!
+
+- `testppd`: String got freed too early
+  In this test program run by `make check` a string was used after
+  already gotten freed. Discovered via a compiler warning, but program
+  could have actually crashed.
+
+- `configure.ac`: Change deprecated AC_PROG_LIBTOOL for LT_INIT (#8)
+
