+ The default paper size for the PostScript driver is now determined
+ using the PAPERSIZE environment variable, or the LC_PAPER locale
+ category on systems that support it. If these are not set, the
+ default is now A4, instead of US letter. To make US letter the
+ default, set PAPERSIZE to "letter" in your environment.
+
+ For developers, the build system now requires Autoconf 2.60 and
+ Automake 1.10.
