OK, this has taken _much_ longer than anticipated, but here it is,<br>
finally!<br>

For a list of mirrors, see <a href="http://www.mostang.com/sane/source.html">http://www.mostang.com/sane/source.html</a><br>
(note that it may take a couple of hours before the mirrors pick the<br>
new version up).<br>
<p>
The relevant section from the NEWS file is appended below.  There were<br>
_lots_ of changes---thanks to everybody who has contributed to this<br>
release!<br>
<p>
An important change as far as documentation is concerned is that now<br>
every backend is being described by a short "description" file (see<br>
backend/FOO.desc).  If you're maintaining a SANE backend, please make<br>
sure that you keep that file up to date.  That way, we can ensure that<br>
the web page (<a href="http://www.mostang.com/sane/sane-backends.html">http://www.mostang.com/sane/sane-backends.html</a>) always<br>
contains the latest list of supported devices.<br>
<p>
Cheers,<br>

---------------------------<br>
New with 0.74:<br>
<p>
* GIMP auto-detection should work again.<br>
<p>
* Service name for remote scanning changed from "saned" to "sane".<br>
  Be sure to update your /etc/services and /etc/inetd.conf if you<br>
  use remote scanning!  We generally try to avoid such incompatible<br>
  changes, but the name "saned" was definitely wrong, so it seemed<br>
  better to change it now.<br>
<p>
* Thanks to Matto Marjanovic work, each backend now comes with a<br>
  .desc file that describes exactly what devices it supports.  These<br>
  description files can be automatically translated into various<br>
  other formats, such as HTML.  See:<br>
<p>
	<a href="http://www.mostang.com/sane/sane-backends.html">http://www.mostang.com/sane/sane-backends.html</a><br>
<p>
  for an example as to what this can do for you.<br>
<p>
* New backend for Kodak DC25 digital cameras (by Peter Fales).<br>
<p>
* Updated Artec backend (by Chris Pinkham).<br>
<p>
* Updated Microtek backend (by Matthew Marjanovic)<br>
<p>
 o Complete rewrite of bit-shuffling, buffering, and color-handling code.<br>
 o Improved rescaling algorithm for expanded resolution scans.<br>
 o Support for 600GS (and maybe ZS, too) (thanks to Oliver Neukum).<br>
 o Support for document autofeeder and IIG (thanks to Ross Crawford).<br>
 o Fixed sane_cancel.<br>
 o sane_get_parameters size estimates are now accurate to the last bit.<br>
 o get_scan_status timeout increased (for 600GS), status code fixed.<br>
 o Fixed parsing of 3-pass bit in INQUIRY data.<br>
 o Stopped sending gamma tables to scanners that don't want them.<br>
 o Made precalibration a bit more robust (always attempt at least one<br>
   scan line now).<br>
 o Much, much code clean-up.<br>
 o Tested &amp; working with saned.  (Atrocious hack so sane_read<br>
   handles buffers smaller than one scanline.)<br>
 o Auto-expand pre/post hold buffers as necessary (fixes some problems<br>
   with single-pass color scans).<br>
 o Added configuration file option to disable precalibration logic.<br>
 o Fixed document size calculations.<br>
 o Added more informative scsi-II note.<br>
 o Remove misnomer "Highscan" from manpage.<br>
 o Updated man-page.<br>
<p>
* Updated Microtek2 backend (by Bernd Schroeder)<br>
<p>
 o changed the code for gamma calculation and added a custom gamma table<br>
   to the options. In some cases this requires an additional memcpy(),<br>
   but the code is now leaner and cleaner.<br>
 o fixed the bugs that the backend didn't compile with non gcc compilers.<br>
 o added an option to control exposure times.<br>
 o rewrote the code that processes the data that is received from the <br>
   scanner and transfers it into the frontend buffer. The smallest unit of<br>
   data that can be copied into the frontend buffer is now a pixel, no<br>
   longer a complete line.<br>
 o added (a yet) undocumented option "strip-height" that allows to control<br>
   the number of lines that is read from the scanner with one "read image".<br>
 o fixed a bug that caused scanimage to sigsegv when calling sane_exit() <br>
   without having written all data into the output file.<br>
 o added code to support scanners with more than 8 bit output per color.<br>
   Due to the lack of such a scanner this functionality is COMPLETELY UNTESTED<br>
   and there are some potential sources of bugs, but at least one could give<br>
   it try.<br>
 o added sanei_config_attach_matching_devices()<br>
 o improved the code for the check if it really is Microtek SCSI-II scanner<br>
 o fixed the "lineart inverted" bug<br>
 o The threshold option in lineart mode is now in the enhancement group<br>
 o changed the default for the resolution<br>
 o The values for the SANE_Params struct are calculated more precisely<br>
 o dito the number of scan lines that fit into the frontend buffer<br>
 o changed some return stati ( replaced SANE_STATUS_INVAL with<br>
   SANE_STATUS_IO_ERROR where the first one is not allowed)<br>
 o completely rewrote the end of scan and cancel scan handling<br>
 o fixed another bug that caused xscanimage to crash with sigsegv<br>
   under some circumstances (check of the inquiry result was wrong)<br>
 o added model code for a Vobis Highscan<br>
 o support for new format of configuration file (including<br>
   "option &lt;opt&gt; &lt;val&gt;")<br>
<p>
* Updated Nikon Coolscan backend (by Didier Carlier).<br>
<p>
* Updated UMAX backend (by Oliver Rauch):<br>
  o Cancelling a scan now works, cancelling a preview still makes problems! <br>
  o Preview fix is activated for Astra 600S, Astra 610S and Vista S6E<br>
    scanners. (calibration by driver still does not work for these scanners). <br>
     - removed button for preview patch <br>
  o Quality calibration / calibration by driver now works for same scanners. <br>
     - added selection for type of shading data calculation <br>
  o Solved problem with black area at top of the image <br>
    (happend only with some SCSI-adapters). <br>
  o Added gamma download format type 0 and type 1 for older scanners. <br>
  o Added Astra 1220S as supported scanner: <br>
     - added 36 gamma input bits support for Astra 1220S <br>
     - added 36 output bits support, but there is no frontend that can<br>
       handle it! <br>
  o Added inquiry for Escom Image Scanner 256 (UMAX UG80). <br>
<p>
* OS/2 (by Yuri Dario):<br>
  o Updated SCSI support so sanei_scsi_find_devices is supported now.<br>
  o Epson parallel support added (by Rocco Caputo &lt;<a href="mailto:troc@netrus.net">troc@netrus.net</a>&gt;)<br>
