+    PACKAGE_VERSION instead. 
+  * Update email address and homepage.
+
+2001-08-08
+  * Released Mustek backend 1.0-106
+
+2001-04-08
+  * Backend status is "stable" now. Hopefully this doesn't mean that new
+    bugs show up now :-)
+
+2001-04-01
+  * Added detection of the Pro models TA (at least the 1200SP Pro).
+  * Added warning about real (not relabeled) Trust scanners.
+
+2001-03-31
+  * Removed comment about brightness and contrast in the description strings
+    because you can't read them anyway in color mode (at least with xsane).
+
+2001-03-31
+  * Released Mustek backend 1.0-105
+
+2001-03-31
+  * Removed compilation warning in gamma_correction.
+  * Fixed handling of tlx and brx when scanning with ADF (bug found by
+    Andreas Rathgeber <rathgeber2000@yahoo.de>).
+  * Fixed bug in linedistance correction (ld_block) concerning ADF. With ADF
+    the linedistance values are ordered in the other direction.
+  * Fixed bug concerning ld correction for the 1200SP 1.00 (frontend hangs).
+    Moved the do-nothing ld correction to its own function. With ADF this
+    scanner doesn't really work in color mode but that's probably a firmware
+    problem.
+
+2001-03-18
+  * 600 II N: Gamma correction in gray mode now works. Length must be 768
+    bytes in gray mode also, cdb size is 6 bytes. Thanks to Jakub Bogusz
+    <qboosh@prioris.mini.pw.edu.pl> who found out about that and wrote a
+    patch.
+
+2001-01-17
+  * Released Mustek backend 1.0-104
+
+2001-01-17
+  * Pro: Do calibration only in Lineart, Gray and Color 24 modes.

+2001-01-03
+  * Added 36 bit color mode for the Paragon Pro scanners.
+
+2000-12-31
+  * Added function little_endian (from coolscan.c) to check the endianess of
+    the current architecture (needed for 16 bit frames).
+  * Added option for Gray fast
+  * Added option for bit depth (8 and 12 bits for the Pro models)
+  * Removed "special" modes from mode option
+  * Removed 48 bit options for the SE Plus. This mode seems to use only
+    interpolated information (but I may be wrong).
+
+2000-12-31
+  * Released Mustek backend 1.0-103
+  
+2000-12-30
+  * Implemented calibration (color and gray mode) for the Paragon 1200 Pro.
+    It's not perfect and needs lots of tests. It may work for the Paragon
+    A3 also but is not tested.
+  * SE 12000 SP Plus calibration is now better but not yet perfect.
+
+2000-12-27
+  * Enabled fast_preview for the Pro scanners (30 dpi).
+  * Increased scan width to 8.6" for 1200 Pro.
+
+2000-12-26
+  * Added calibration for the SE 12000 SP Plus. Doesn't fully work until now 
+    (images are too dark and colored).
+
+2000-12-23
+  * Added option for Legal format (because the ScanExpress 12000 SP A4 size
+    scanner can't be distinguished from the Paragon 1200 LS Legal size scanner
+    by software).
+  
+2000-12-21
+  * Added a few checks for Null-Pointers.
+  * Removed old code for SE calibration.
+  * Added option "quality calibration" for SE Plus scanners
+
+2000-12-21
+  * sane-backends 1.0.4 was released (including Mustek backend 1.0.102).
+
+2000-12-10
+  * Released Mustek backend 1.0-102
+  
+2000-12-09
+  * Fixed wrong comment in encode_resolution
+  * Added missing test for return status in sane_start
+  * Fixed wrong calculation of tlx and tly for Pro series scanners
+
+2000-12-05
+  * Released Mustek backend 1.0-101
+ 
+2000-12-05
+  * Fixed lamp setting (avoid problems with some SE scanners).
+
+2000-12-01
+  * Reduced scan area for Paragon 1200 SP PRO (to avoid bumping the scan slider
+    at the end).
+  * Removed warning for 1200 SP PRO.
+
+2000-11-26
+  * Released Mustek backend 1.0-100
+
+2000-11-26
+  * Default for "fast preview" is "false" now because this option doesn't work
+    for all SE scanners correctly.
+  * Added more debug output for area_and_windows.
+  * Added more debug output for set_window.
+  * Set minimum tly for 8000SP to 0.
+  * Don't use block mode for Paragon 8000 SP scanners because this breaks
+    color mode with firmware 2.x.
+
+2000-11-19
+  * Paragon 6000 SP doesn't use block mode any more. It's a bit faster now.
+  * Updated sane-mustek.man concerning buffersize and blocksite.
+
+2000-11-17
+  * Updated manpage concerning force-wait. Some minor corrections and additions
+  * Added option force-wait to mustek.conf and did some minor changes.
+
+2000-11-16
+  * With option force_wait set, the backend waits also before sending the
+    inquiry command. This seems to be necessary for the 600 II N.
+
+2000-11-12
+  * Use SANE_Int, SANE_Bool, SANE_Word for int wherever this seems to
+    be appropriate.
+  * Move macros to mustek.h.
+  * Code cleanup.
+
+2000-11-11
+  * OPT_GRAY_PREVIEW is now called OPT_FAST_PREVIEW.
+  * For SE scanners use 36/38 dpi color for fast preview.
+  * use include "../include/sane/" instead of "sane/"
+  * go back to old scheme for SE scanners in color mode (faster scans
+    couldn't be reproduced)
+
+2000-11-10
+  * added more debug output in constrain_value
+
+2000-11-05
+  * Released backend version 1.0-99.
+
+2000-11-05
+  * Added support for TAIV for SE 12000 SP. Lamp is turned off while
+    scanning (seems to work for firmware >= 2.00)
+  * Adjusted transparency adapter support for all ScanExpress scanners.
+    The 12000 A3 SP can only do A4 beacuse I don't have the right TA.
+  * don't use u_int* types in mustek.h because the definitions for these 
+    types are not included
+
+2000-11-04
+  * SE scanners can now scan 75, 100, 150, 200, 250, 300, 400, 500, 600,
+    900 and 1200 dpi in color mode (the 1200 dpi models). These are fixed 
+    resolutions, a resolution >= the wanted resolution is selected. This
+    makes preview and some resolutions faster than before (at least for
+    some scanners), because lower resolutions can be used.
+  * Minimum scan resolution is 60 dpi in gray and lineart and 75 dpi in 
+    color mode for the SE scanners now.
+  
+2000-10-29
+  * Fixed a bug concerning block LD. Paragon 1 and 2 were exchanged.
+  * Paragon 12000SP color mode works now without garbage at the end
+  * Fixed Paragon 1200 SP Pro color mode > 600 dpi (rounding problem)
+  * Temporarily disabled 48 bit color mode for release
+
+2000-10-25
+  * Detect support for TA IV (transparency adapter for ScanExpress scanners)
+  * TA IV supported now; lamp is turned off at least for SE 1200 SP Plus
+    scanners
+  * Adjusted scan area for TA: SE 12000SP Plus
+  * Simplify enlarge x
+  * Set tl-y to 0 for all ScanExpress scanners
+  * First attempt to support 48 bits color mode (SE 12000 SP Plus)
+
+2000-10-22
+  * Detect SE 12000 SP Plus properly
+  * Cover sensor only checked for SE models that support this feature
+
+2000-10-21
+  * Removed MAX_BLOCKSIZE macro (not used anymore).
+
+2000-10-03
+  * Released backend version 1.0-98.
+  
+2000-10-03

+  * Re-enabled double buffering.
+
+2000-10-02
+  * Zero out inquiry memory block before reading inquiry.
+
+2000-10-01
+  * Fixed fix_line_distance_block.
+  * Adjusted Paragon 12000 SP to use block LD correction if necessary.
+  * removed LD MFS (wasn't used anyway)
+
+2000-09-30
+  * Set blockbuffer size to 2 MB for Paragon series II scanners.
+  * Fix sane_cancel for Paragon series II scanners
+  * Fix speed and grain for Paragon series II scanners

+  * Added check for handle != 0 in sane_set_io_mode
+  * Added check for handle != 0 in sane_get_select_fd
+  * Output option title in sane_get_option_descriptor if name is null
+
+2000-09-24
+  * Released backend version 1.0-97.
+  
+2000-09-24
+  * Added RGB brightness and contrast for 3pass scanners
+  * Brightness and contrast is +-100% for 3pass scanners now
+
+2000-09-23
+  * Paragon 12000CX uses pixel unit now.
+  * Paragon 6000CX uses pixel unit now (MSF-06000CZ).
+  * Option "force backtracking" is enabled by default now
+  * Option "scan speed" is set to "fastest" by default now
+  * Add option "force-wait" (for mustek.conf). If enabled, wait for scan
+    head to return to start position after scan.

+
+2000-09-19
+  * Return sane_status_cancelled in sane_read if last scan was cancelled.
+
+2000-09-18
+  * Changed speed_code to use values between 1...5 for 3pass scanners.
+    I don't know yet if these are correct for the other scanners, too.
+  * Don't do a stop scan for 3pass scanners (only when cancelling).
+  * Set bit 0 of first byte of area_and_windows for gray + color.
+  * Paragon 6000CX uses pixel unit now (MFS-06000CX).
+  * Pixel unit for 3pass scanners is now supported
+
+2000-09-17
+  * changed maximum y range of MFS-800 II SP to 288 mm because of
+    a report of scanner touching the end.
+
+2000-09-10
+  * added some testing (result != null and arg !=0) in sense_handler
+    (found by Martin Blasczyk)
+
+2000-08-20
+  * Paragon series II is also using blockmode now.

+  * 800 II SP works now in new block mode (get_image_status is needed
+    before each block)
+
+2000-08-17
+  * Removed some warnings from sanei_ab306.c.
+
+2000-08-16
+  * Fixed some bugs in fix_linedistance_block. Paragon 600 models seem to
+    work now. 800 II SP freezes, however.
+  * Fixed segmentation fault for the 600 II N in ld correction code.
+
+2000-08-15
+  * Changed handling of three pass scanners (MUSTEK_FLAG_THREE_PASS instead of
+    !MUSTEK_FLAG_SINGLE_PASS).
+  * Added flags for Paragon series I and II (MUSTEK_PLAG_PARAGON_1 and
+    MUSTEK_PLAG_PARAGON_2).
+  * Distinguish between three-pass, Paragon series 1, Paragon series 2,
+    ScanExpress, Pro and N type scanners.
+  * Added support for scanning the whole image in one block without
+    backtracking for the Paragon series II scanners.
+  * Added fix_linedistance_block: like linedistance_normal but broken
+    up into several SCSI buffers.
+
+2000-08-14
+  * Changed again linedistance correction for the Paragon 12000 SP 1.11.
+    This seems to be a never ending story.
+  * Set the minimum dpi value to 30. Some scanners (e.g. the MFS 8000SP
+    v 2.04) block the SCSI bus with lower resolutions.
+
+2000-08-12
+  * Added support for Paragon 1200 SP Pro.
+  * Added support for ScanExpress A3 SP.
+  * Removed detection for " C12" and " C04" (don't seem to exist).
+  * Changed SCSI read request scheme. Now two requests with half of the
+    maximum SCSI buffer size are entered. Standard buffer size is 128 kB,
+    so the buffer sent to the scanner is 64 kB for all types of scanners.
+  * sane_read now reads more than 4096 bytes from pipe (if available).
+

+
+2000-07-30
+  * Released backend version 1.0-95
+
+2000-07-30
+  * Removed while {wait ()} loop. Used waitpid() instead. Maybe this cures

+  * Removed dead code.
+
+2000-07-28
+  * Released backend version 1.0-94
+
+2000-07-29
+  * Use #include "sane/..." instead of #include <sane/...>.

+2000-07-27
+  * Released backend version 1.0-93
+
+2000-07-27

+    page
+
+2000-07-25

+
+2000-07-25
+  * Released backend version 1.0-92
+  
+2000-07-24
+  * Fixed ADF handling (output was mirrored in x direction). Gray and lineart
+    seems to work now. Color and halftone modes look somewhat crazy.
+  * Removed comment about lack of testing of ADFs in manpage. They are
+    tested to work now with most scanner at least basically.
+  * removed braindead test for Pro series concerning gamma table length
+    (discovered by Jan-Erik Karlsson).

+  * Released backend version 1.0-90
+
+2000-07-15
+  * Added MUSTEK_FLAG_LD_NONE for MFS-08000SP and removed warning for
+    this scanner. Added TA support. First report for this device from
+    Roland Koebler.
+  * Changed LD correction system. Some scanners (e.g. the 800 II SP)
+    seem to need different LD correction depending on resolution.
+    Now with LD_NORMAL max_value is checked and correction is only done
+    if it is != 0. Hope this works for all scanners.
+  * Moved the comment after the example port entry in mustek.conf to
+    the next line. Now this line should work.
+  * Updated manpage concerning PP scanners and 600 II N.
+
+2000-06-30
+  * Released backend version 1.0-89
+
+2000-06-30

+
+2000-06-28
+  * Released backend version 1.0-88
+
+2000-06-28
+  * Changed again linedistance handling for the Paragon 1200SP. This
+    time version 1.07 seems to need a special treetment. Even with normal
+    linedistance correction the image is corrupted at buffer boundaries
+    in color mode. Maybe a firmware bug? Thanks to Michael Prechtl for
+    all his tests.
+
+2000-06-25

+
+2000-06-16
+  * addded debugging output in sane_control_option
+  * added gamma correction for Paragon 1200 A3 Pro (doesn't work correctly yet)
+
+2000-06-15
+  * removed old config file reading system.
+
+2000-06-14
+  * Preliminary support for the Mustek Paragon 1200 A3 Pro. Only grayscale
+    mode works so far. Missing: Gamma correction and calibration. The scanner
+    is locked after each scan.
+
+2000-06-12
+  * Fixed bug in sane_control_option. option was not checked for negative
+    values. Thanks to Jochen Eisinger.
+  * Code cleanup and reorganization for inclusion of the Paragon 1200 A3 Pro.
+

+    Thanks to Jochen Eisinger for spotting this.
+
+2000-06-05
+  * Fixed some debug messages in fix_linedistance_se
+
+2000-06-04
+  * released backend version 1.0-85
+
+2000-06-04
+  * changed (again) Paragon 12000 SP linedistance handling, now 1.02 uses

+  * fixed some long lines (>80 chars)
+
+2000-06-03

+  * simpler linedistance debug output, only for 1-pass Paragon scanners
+
+2000-06-02
+  * removed code in dev_read_start which was never called (suggestion
+    from Jan-Erik Karlsson)
+
+2000-05-21
+  * added double buffering (trying to copy the scsi buffer to the frontend
+    while getting a new one). This probably won't work on all
+    platforms and with all SCSI host adapters but in this case performance
+    shouldn't be worse than before.
+
+2000-05-21
+  * released backend version 1.0-83
+
+2000-05-21
+  * The Mustek Paragon 1200 A3 PRO is now detected. This is only a test

+    These modes didn't work for any of my scanners.
+  * added more debug output for ADF and TA

+  * fixed lineart and color scanning >600 dpi for the SE 12000SP
+  * added variable debug_level to be faster without debugging in attach ()
+  * fixed bug in mustek.conf handling; positional options were applied
+    to the first device only
+  * added an option to mustek.conf: "buffersize". This overwrites the
+    default scan buffer sizes. The unit is kilobytes.
+  * adjusted mustek.conf to more reasonable defaults
+  * update manpage and mustek.desc to reflect the changes
