+ * 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

+ 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

+ * 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

+ * 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

+ * Changed Halftone handling, removed grain size
+
+2000-09-22

+
+2000-09-19
+ * Return sane_status_cancelled in sane_read if last scan was cancelled.
+

+ * 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

+ (found by Martin Blasczyk)
+
+2000-08-20
+ * Paragon series II is also using blockmode now.
+ * Removed warning from mustek.c.
+ * Fixed (maybe) problem in scsi_sense_wait_ready and added more
+ debug output.
+
+2000-08-18

+
+2000-08-17
+ * Removed some warnings from sanei_ab306.c.

+ * 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).

+ 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).

+
+2000-07-30
+ * Released backend version 1.0-95
+
+2000-07-30
+ * Removed while {wait ()} loop. Used waitpid() instead. Maybe this cures
+ some reported freezes. It's cleaner anyway.
+ * Removed dead code.
+
+2000-07-28
+ * Released backend version 1.0-94
+
+2000-07-29

+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).
+
+2000-07-22
+ * Fixed margin positions of MFS 6000CX and removed warning.

+ * Released backend version 1.0-91
+
+2000-07-18

+2000-07-15
+ * 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

+2000-06-28
+ * 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.

+
+2000-06-14
+ * 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

+ values. Thanks to Jochen Eisinger.
+ * Code cleanup and reorganization for inclusion of the Paragon 1200 A3 Pro.

+ * 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
+ normal LD corrections, all other use none. We'll see, if this works.

+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

+ * Scan source option is only available if TA or ADF is present. For
+ SE and N models TA is always available because it can't be detected
+ by hardware
