		3	+ * Changes listed on today's date are numerous and reflect
		4	+ significant enhancements to qpdf's lexical layer. While many
		5	+ nuances are discussed and a handful of small bugs were fixed, it
		6	+ should be emphasized that none of these issues have any impact on
		7	+ any output or behavior of qpdf under "normal" operation. There are
		8	+ some changes that have an effect on content stream normalization
		9	+ as with qdf mode or on code that interacts with PDF files
		10	+ lexically using QPDFTokenizer. There are no incompatible changes
		11	+ for normal operation. There are a few changes that will affect the
		12	+ exact error messages issued on certain bad files, and there is a
		13	+ small non-compatible enhancement regarding the behavior of
		14	+ manually constructed QPDFTokenizer::Token objects. Users of the
		15	+ qpdf command line tool will see no changes other than the addition
		16	+ of a new command-line flag and possibly some improved error
		17	+ messages.
