font "S". That technique produced glyphs slightly larger than those
in grops's "SS" font. Thanks to Deri James.
+* gropdf now subsets embedded fonts by default, meaning that it stores
+ only the glyphs a document actually uses. Font subsetting usually
+ reduces the size of the PDF gropdf creates. Thanks to Deri James.
+
+* gropdf supports a new `--opt` command-line option, permitting a few
+ features, including font subsetting, to be selectively enabled.
+ Thanks to Deri James.
+
+* gropdf now emits PDFs that conform to the PDF 1.7 standard (also
+ known as ISO 32000). Its new `--pdfver` command-line option permits
+ production of PDF 1.4-conformant output instead. Thanks to Deri
+ James.
+
+* gropdf supports a new `pdf: pagenumbering` device extension command
+ and `pdfpagenumbering` convenience macro, allowing control of the
+ page numbers in a PDF reader's overview panel. It is common for a
+ document to number early pages with Roman numerals and then restart
+ page enumeration at decimal 1 for its main matter. Thanks to Deri
+ James.
+
+* gropdf now offers its own implementations of the "pdfmark" macro
+ package's "pdfhref" and other macros, supporting internal (bookmarks,
+ named destinations) and external (URL) hyperlinks, and the
+ specification of hotspots for link text. For example, when bundling
+ multiple man pages into a collection, as the supplied
+ groff-man-pages.pdf document and the Linux man-pages project do,
+ references to man pages within the collection are supported with
+ internal hyperlinks, and those outside with external ones. Thanks to
+ Deri James.
+
+* gropdf now supports characters outside the Unicode Basic Latin subset
+ in bookmarks, named destinations, and external hyperlinks. (They
+ must be encoded using groff's Unicode special character escape
+ sequences; the preconv preprocessor is helpful to simply this
+ requirement.) Thanks to Deri James.
+
+* gropdf now recognizes a `GROPDF_OPTIONS` environment variable,
+ interpreting it as a space-separated list of command-line options.
+ Explicit command-line options override any settings from this
+ environment variable. You can use this variable to obviate passing
+ options to gropdf via groff's `-P` option. Thanks to Deri James.
+
* grops(1), the PostScript output driver, now supports fonts encoded
using UTF-16. Indicate the encoding by including the string
"-UTF16-" within the font's name as specified by the "internalname"
