Some bugs have been fixed. The main new feature is that information is automatically inserted into the PostScript output such that if it is converted to a PDF, cross-references and page numbers in indexes become clickable links.
The only changes in this release are code and test tidies. Some are to get rid of compiler warnings, some are to update to the current libpng API (what it was using is deprecated), and some are to make the tests that involve JPEGs work with different versions of libjpeg.
This release adds "configure" options to disable JPEG and/or PNG
support. Some #ifdefs were missing when either of these were not
supported, leading to compilation errors; this has been fixed.
