CHANGES IN CUPS v1.0.5

	- The HP-GL/2 filter did not correctly set the pen color

          for pens other than #1.

	- The scheduler would only accept 26 simultaneous jobs

          under some OS releases (mkstemp() limitation.)  It now

          handles up to 2^32 simultaneous jobs.

	- The PostScript filter loaded the printer's PPD file

          twice.

	- The PAM authentication code now uses pam_strerror() to

          provide a textual error message in the error_log file.

	- The scheduler now copies PPD and interface script

          files instead of moving them; this fixes installations

          with a separate requests directory.

	- The PostScript RIP did not generate correct 6-color

          output.

	- Several filters were marking PPD options twice when

          they didn't need to.

	- The scheduler did not save the printer or class state

          after an accept-jobs or reject-jobs operation.

	- The cupsGetDefault() function now ignores the PRINTER

          environment variable if it is set to "lp".

	- New ippErrorString() function to get textual error

          messages.

	- Better error reporting in the System V commands.

	- The lpadmin and lpstat commands always tried to

          connect to the default server.

	- The text filter didn't load the charset files from the

          correct location.

	- Wasn't sending a WWW-Authenticate: field to HTTP

          clients when authentication was required.

	- httpSeparate() didn't always set the default port

          number for known methods.

	- The HP-GL/2 filter now looks for "PSwidth,length"

          instead of (the correct) "PSlength,width" as

          documented by HP.  It appears that many major CAD

          applications are broken and this change allows the

          auto-rotation to work with them.

	- The IPP "printer-resolution" option was not being

          translated.

	- The charset files did not include the Microsoft

          "standard" characters from 128 to 159 (unused by the

          ISO-8859-x charsets)

	- The scheduler was chunking the Content-Type field from

          CGI programs; this problem was most noticeable with

          Microsoft Internet Explorer 5.

	- By popular demand, the printers, jobs, and classes

          CGIs no longer force a reload of the page every 10/30

          seconds.

	- The scheduler incorrectly required that the IPP client

          provide a document-format attribute for the

          validate-job operation.

	- Clients that sent bad IPP requests without the

          required attributes-natural-language and

          attributes-charset attributes would crash the

          scheduler.

CHANGES IN CUPS v1.0.4

	- Documentation updates.

	- Jobs would get stuck in the queue and wouldn't print

	  until you enabled the queue.

	- The lp and lpr commands now catch SIGHUP and SIGINTR.

	- The lp and lpr commands now use sigaction or sigset

	  when available.

	- CUPS library updates for WIN32/OS-2

CHANGES IN CUPS v1.0.3

	- Documentation updates.

	- The lpq man page was missing.

	- The configure script was not properly detecting the

	  image libraries.

	- The top-level makefile was calling "make" instead of

	  "$(MAKE)".

	- PostScript filter fixes for number-up, OutputOrder,

	  and %Trailer.

	- The imagetops filter didn't end the base-85 encoding

	  properly if the image data was not a multiple of 4

	  bytes in length.

	- The imagetoraster filter didn't generate good banded

	  RGB or CMY data (was dividing the line width by 4

	  instead of 3...)

	- The imagetoraster filter now records the bounding

	  box of the image on the page.

	- The CUPS image library cache code wasn't working as

	  designed; images larger than the maximum RIP cache

	  would eventually thrash using the same cache tile.

	- The CUPS image library TIFF loading code didn't

	  handle unknown resolution units properly; the fixed

	  code uses a default resolution of 128 PPI.

	- cupsGetClasses() and cupsGetPrinters() did not free

	  existing strings if they ran out of memory.

	- The scheduler logs incorrectly contained 3 digits for

	  the timezone offset instead of 4.

	- The scheduler now does a lookup for the default user

	  and group ID; the previous hardcoded values caused

	  problems with the LPD backend.

	- The cancel-job operation now allows any user in the

	  system group to cancel any job.

	- The cancel-job operation stopped the print queue if

	  the job was being printed.

	- Now only stop printers if the backend fails. If the

	  filter fails then the failure is noted in the

	  error_log and printing continues with the next file in

	  the queue.

	- Now log whether a filter fails because of a signal

	  or because it returned a non-zero exit status.

	- The root user now always passes the system group test.

	- Printers with an interface script and remote printers

	  and classes didn't have a printer-make-and-model

	  attribute.

	- Added logging of lost/timed-out remote printers.

	- The HP-GL/2 filter was scaling the pen width twice.

	- Updated the HP-GL/2 filter to use a single SP (Set

	  Pen) procedure.  This makes the output smaller and is

	  more appropriate since the filter keeps track of the

	  pen states already.

	- The scheduler didn't handle passwords with spaces.

	- The IPP backend now does multiple copies and retries

	  if the destination server requires it (e.g. HP

	  JetDirect.)

	- The disable command didn't implement the "-c" option

	  (cancel all jobs.)

	- Changed the CMYK generation function for the image file

	  and PostScript RIPs.

	- The lp command didn't support the "-h" option as

	  documented.

	- The AppSocket, IPP, and LPD backends now retry on all

	  network errors.  This should prevent stopped queues

	  caused by a printer being disconnected from the

	  network or powered off.

	- The scheduler now restarts a job if the corresponding

	  printer is modified.

	- The image RIPs now rotate the image if needed to fit

	  on the page.

CHANGES IN CUPS v1.0.2

	- The HP-GL/2 filter didn't always scale the output

	  correctly.

	- The HP-GL/2 filter now supports changing the page size

	  automatically when the "fitplot" option is not used.

	- The cancel-job operation was expecting a resource name

	  of the form "/job/#" instead of "/jobs/#"; this

	  prevented the cancel and lprm commands from working.

	- The backends didn't log pages when files were printed

	  using the "-oraw" option.

	- The authorization code did not work with the Slackware

	  long shadow password package because its crypt() can

	  return NULL.

	- The chunking code didn't work for reading the response

	  of a POST request.

	- cupsGetPPD() now does authentication as needed.

	- The N-up code in the PostScript filter didn't work

	  with some printers (grestoreall would restore the

	  default blank page and device settings).

	- The N-up code in the PostScript filter didn't scale

	  the pages to fit within the imageable area of the

	  page.

	- Wasn't doing an fchown() on the request files.  This

	  caused problems when the default root account group

	  and CUPS group were not the same.

CHANGES IN CUPS v1.0.1

	- Documentation updates.

	- Fixed a bunch of possible buffer-overflow conditions.

	- The scheduler now supports authentication using PAM.

	- Updated the Italian message file.

	- httpEncode64() didn't add an extra "=" if there was

	  only one byte in the last three-byte group.

	- Now drop any trailing character set from the locale

	  string (e.g. "en_US.ISO_8859-1" becomes "en_US")

	- Fixed "timezone" vs "tm_gmtoff" usage for BSD-based

	  operating systems.

	- Updated IPP security so that "get" operations can be

	  done from any resource name; this allows the CGIs to

	  work with printer authentication enabled so long as

	  authentication isn't turned on for the whole "site".

	- The IPP code didn't properly handle the "unsupported"

	  group; this caused problems with the HP JetDirect since

	  it doesn't seem to support the "copies" attribute.

	- The HTTP chunking code was missing a CR LF pair at the

	  end of a 0-length chunk.

	- The httpSeparate() function didn't handle embedded

	  usernames and passwords in the URI properly.

	- Doing "lpadmin -p printer -E" didn't restart printing

	  if there were pending jobs.

	- The cancel-job operation now requires either a

	  requesting-user-name attribute or an authenticated

	  username.

	- The add-printer code did not report errors if the

	  interface script or PPD file could not be renamed.

	- Request files are now created without world read

	  permissions.

	- Added a cupsLastError() function to the CUPS API to

	  retrieve the IPP error code from the last request.

	- Options are now case-insensitive.

	- The lpq command now provides 10 characters for the

	  username instead of the original (Berkeley standard)

	  7.

	- The cancel command needed a local CUPS server to work

	  (or the appropriate ServerName in cupsd.conf)

	- The cancel and lprm commands didn't report the IPP

	  error if the job could not be cancelled.

	- The lp and lpr commands didn't intercept SIGTERM to

	  remove temporary files when printing from stdin.

	- The lp and lpr commands didn't report the IPP error if

	  the job could not be printed.
