+        Note to people including qpdf in distributions: the
+        <filename>.la</filename> files generated by libtool are now
+        installed by qpdf's <command>make install</command> target.
+        Before, they were not installed.  This means that if your
+        distribution does not want to include <filename>.la</filename>
+        files, you must remove them as part of your packaging process.

+        Major enhancement: API enhancements have been made to support
+        parsing of content streams.  This enhancement includes the
+        following changes:

+          <para>
+           <function>QPDFObjectHandle::parseContentStream</function>
+           method parses objects in a content stream and calls
+           handlers in a callback class.  The example
+           <filename>examples/pdf-parse-content.cc</filename>
+           illustrates how this may be used.

+           content streams.

+           Method <function>QPDFObjectHandle::getTypeCode()</function>
+           returns an enumerated type value representing the
+           underlying object type.  Method
+           <function>QPDFObjectHandle::getTypeName()</function>
+           returns a text string describing the name of the type of a
+           <type>QPDFObjectHandle</type> object.  These methods can be
+           used for more efficient parsing and debugging/diagnostic
+           messages.

+        errors in content streams will now be reported.

+           All C-style casts in C++ Code have been replaced by C++
+           casts, and many casts that had been included to suppress
+           higher warning levels for some compilers have been removed,
+           primarily for clarity.  Places where integer type coercion
+           occurs have been scrutinized.  A new casting policy has
+           been documented in the manual.  This is of concern mainly
+           to people porting qpdf to new platforms or compilers.  It
+           is not visible to programmers writing code that uses the
+           library

+           Some internal limits have been removed in code that
+           converts numbers to strings.  This is largely invisible to
+           users, but it does trigger a bug in some older versions of
+           mingw-w64's C++ library.  See
+           <filename>README-windows.txt</filename> in the source
+           distribution if you think this may affect you.  The copy of
+           the DLL distributed with qpdf's binary distribution is not
+           affected by this problem.

+        The RPM spec file previously included with qpdf has been
+        removed.  This is because virtually all Linux distributions
+        include qpdf now that it is a dependency of CUPS filters.

+           Overridden compressed objects are properly handled.
+           Before, there were certain constructs that could cause qpdf
+           to see old versions of some objects.  The most usual
+           manifestation of this was loss of filled in form values for
+           certain files.
