Release 3.1.2 (Public Release - 1997.02.06)

- Updated Implementation Version Name and Implementation Class UID to
  reflect the new version 3.1.2
  Affects: dcmdata/include/dcuid.h

- Added code in imagectn to print the time when an association request
  is received.
  Affects: imagectn/apps/imagectn.cc

- Added capability for a DcmDirectoryRecord to record its position in
  the DICOMDIR file when being read.  Previously this information was
  only computed when a DICOMDIR was being written.
  Affects: dcmdata/libsrc/dcdirrec.cc

- Updated preliminary Apple Macintosh support for the Metrowerks CodeWarrior
  version 11 compiler and environment.  Either the GUSI library or a WinSock
  library are needed (both are on the CodeWarrior CD but GUSI comes with
  source code and seems more stable).  Corrected for incompatibilities
  in the timeval structure between unix.h and winsock.h
  Problems remain with the network interactions when used when other
  TCP/IP applications are active (this may be a MacOS/OpenTransport problem).
  Affects: config/include/cfmwerks.h
            dcmdata/apps/dcmdump.cc
            dcmdata/libsrc/dcdicdir.cc
            dcmdata/libsrc/dcdirrec.cc
            dcmnet/include/dcompat.h
            dcmnet/include/dicom.h
            dcmnet/libsrc/dcompat.cc
            dcmnet/libsrc/dimcond.cc
            dcmnet/libsrc/dimse.cc
            dcmnet/libsrc/diutil.cc

- Fixed bug when creating unique identifers.  No check was made to ensure
  that negative numbers never appeared in a UID.  Also added an
  implementation of a simple gethostid() function for systems which
  lack this function (e.g. Mac & Windows).  The implementation requires
  TCP/IP to be available.
  Affects: dcmdata/libsrc/dcuid.cc

- Fixed crashing bug in the worklist database search routines.  A badly
  formed date or time matching key was not being caught.  Also added
  some preliminary error checking of maching keys prior to database
  search.  Malformed keys will be noted as offending elements and the
  database search routines will return an error.
  Affects: wlistctn/libsrc/wkrlstdb.cc
           wlistctn/libsrc/wkrlstdb.h

- Corrected usage message for the worklist database test program wltest.
  Affects: wlistctn/tests/wltest.cc

- Corrected some entries in the example worklist database which used
  an incorrect character as value multiplicity deliminator.
  Affects: wlistctn/wlistdb/OFFIS/wklist1.dump
           wlistctn/wlistdb/OFFIS/wklist3.dump
           wlistctn/wlistdb/OFFIS/wklist5.dump
           wlistctn/wlistdb/OFFIS/wklist6.dump
           wlistctn/wlistdb/OFFIS/wklist8.dump

- Added some simple documentation for the movescu utility program.
  Added:   dcmnet/docs/movescu.txt

- Modifed the incoming association negotiation behaviour of movescu
  so that the Storage SCP code now will accept any presentation context
  for a Storage SOP Class based on the table of Storage SOP Classes
  exported in dcuid.h
  Affects: dcmnet/apps/movescu.cc

- Added a set of example modality worklist queries.
  Added:   wlistctn/wlistqry
           wlistctn/wlistqry/README
           wlistctn/wlistqry/wlistqry0.dump
           wlistctn/wlistqry/wlistqry1.dump
           wlistctn/wlistqry/wlistqry2.dump

           wlistctn/wlistqry/wlistqry11.dump
           wlistctn/wlistqry/wlistqry12.dump

- Added bugfix for WINSOCK support.  The required WINSOCK version
  number was being incorrectly set to version 0.1.  The fixed
  WINSOCK initialisation now uses the MAKEWORD macro to correctly
  set the required version number. This bugfix was contributed
  by Dr. Yongjian Bao of Innomed GmbH, Germany.
  Affects: dcmnet/apps/echoscu.cc
           dcmnet/apps/findscu.cc
           dcmnet/apps/movescu.cc
           dcmnet/apps/storescu.cc
           dcmnet/apps/storescp.cc

- Added support for SGI IRIX systems using GCC 2.7.x
  Irix declares bzero() in bstring.h which is included from libc.h
  Configure now also looks for a bzero() prototype in libc.h if
  available.
  Affects: config/configure
           config/configure.in

- Added support for HP-UX 9.05 systems using GCC 2.7.2.1
  HP-UX 9.05 declares the select() system call unusually:
  Declaration is in <sys/time.h> and args 2-4 are int* instead
  of struct fd_set *.
  This requires an extra check in the config modules.
  Affects: config/acconfig.h
           config/aclocal.m4
           config/configure
           config/configure.in
