Hi Werner,
to answer your question, I report to you only the "headers" of the 8.64 and
8.63 releases changelogs from the file
/doc/History8.htm
you can find decompressing the ghostscript-8.64.tar.bz2 file that you can
download from
http://ghostscript.com/GPL_Ghostscript_8.64.html
I will next put History8.htm file as attachment to this issue.
So that read this two sections:
------------------------------------------------------
Version 8.64 (2009-02-02)
This is the fifth scheduled release in the stable Ghostscript 8.6x series.
Approximately 100 bugs have been fixed since the 8.63 release.
Of particular note in this release are improvements to overprint and spot color
support in documents with transparency, improvements to PDF and PS output,
proper handling of PDF-specific text rendering modes and support for reading
AES-encrypted PDF documents.
Also improved is handling of CJK text, especially in vertical writing modes,
memory footprint processing some files at high resolution and support for using
the system's default paper size on unix.
The interpreter's handling of color spaces has been moved from PostScript code
to C.
A number of the included printer drivers and cups wrappers have been updated to
support a PDF-based workflow. Also fixed are several long-standing bugs in the
pcl drivers with respect to duplex, resolution and paper tray selection.
------------------------------------------------------
Version 8.63 (2008-08-01)
This is the fourth scheduled release in the stable Ghostscipt 8.6x series. It
corresponds to the 1.53 release of GhostPDL.
Approximately 238 bugs have been fixed since version 8.62. Of particular note
are robustness and performance improvements with large files, invalid PDF, and
font handling.
The major new feature of this release is multithreaded rendering. This can be
requested by passing -dNumRenderingThreads=n on the command line. The input
document is first parsed, and then each page is split into n bands which are
rendered concurrently. This can provide a significant reduction in processing
time on multi-core systems.
Images are now always interpolated in their source colorspace. This improves
correctness for XPS documents and avoids bypassing the custom color management
callbacks for interpolated images. Interpolation and color management are both
expensive operations, so this affects performance with large images. The effect
can be positive or negative depending on the file and the target resolution. If
performance is a problem, we suggest running with -dNOINTERPOLATION.
Support for OpenPrinting Vector devices has been upgraded to version 1.0.
There are two new devices in this release, both experimental. Behdad Esfahbod
has contributed a cairo output device which uses the cairo graphics library to
generate PDF, SVG, EPS, or PNG files, based on the requested filename
extension. The svgwrite device directly outputs Scalable Vector Graphics, the
W3C XML vector graphics format. Both support only vector art at this point;
text and images will not be represented efficiently.
------------------------------------------------------
Furthermore I use the excellent GPL printer "driver"
http://foo2qpdl.rkkda.com/
that is ghostscript based (see the simple schema in the home page) to print on
my Samsung CLP-610ND, to which I made some bugfix contribution to the autor
(duplex support, ...). So I wanto to obtain the maximum from it.
Hope can help,
Carlo

- The QPDL driver an alternative to the classic Splix (SPL driver) that you can
find here

updated to ghostscript 8.64, too!!!
