 	newer version of gcc and MSVC toolchains. Add several cosmetic
 	improvements to build output in CI.
+	* Added LL_FMT to config.h.in. This is populated automatically by
+	autoconf, but if build with your own build system, you may need to
+	define it as whatever the format string needed by printf for long
+	long is. Usually this is "%lld", but it can be "%I64d" for some

+          When concatenating content streams, as with
+          <option>--coalesce-contents</option>, there were cases in
+          which qpdf would merge two lexical tokens together, creating
+          invalid results. A newline is now inserted between
+          merged content streams if one is not already present.

+          streams whose stream data had been replaced using a stream
+          data provider if those streams had indirect filters or
+          decode parameters. This is a rare corner case.

+          Ensure that the caller's locale settings do not change the
+          results of numeric conversions performed internally by the
+          qpdf library. Note that the problem here could only be
+          caused when the qpdf library was used programmatically.
+          Using the qpdf CLI already ignored the user's locale for
+          numeric conversion.

+          supported) Ubuntu LTS release, but would work on most
+          reasonably recent Linux distributions. It contains only the
+          executables and required shared libraries that would not be
+          present on a minimal system. It can be used for including
+          qpdf in a minimal environment, such as a docker container.
+          The zip file is also known to work as a layer in AWS Lambda.

+	  The method <function>InputSource::unreadCh(unsigned
+	  char)</function> is deprecated and will be removed in qpdf
+	  11. It has never worked properly to pass a character to
+	  <function>unreadCh</function> other than the most recently
+	  read character. If you happen to be deriving a class from
+	  <type>InputSource</type>, just implement
+	  <function>unreadCh</function> to seek backward by one
+	  character if the current position is greater than 0. If you
+	  are calling this in your own code, replacing with
+	  <literal>seek(-1, SEEK_CUR)</literal> should work in all
+	  cases.
