ANNOUNCEMENT

Version 3.6.5 of the OFFIS DCMTK (DICOM ToolKit) software is now available for
public release.  This is a minor release that includes the following changes
over the previous version 3.6.4:

- DCMTK 3.6.5 builds correctly on older and up-to-date versions of GNU gcc
  (4.4.7 to 9.2.0), Clang (3.4.2 to 9.0.0), AppleClang (11.0.0), Microsoft
  Visual Studio (2008 to 2019), SunPro CC (5.14 and 5.15) and IBM XL C/C++
  (16.1.1.3).

- Tested with the following operating systems/environments:

  - Android on arm64
  - Cygwin on x86_64
  - FreeBSD on x86_64
  - Linux on x86_64 and x86
  - MacOS X on x86_64
  - NetBSD on x86_64
  - OpenBSD on x86_64
  - OpenIndiana on x86
  - Solaris on x86
  - Windows (and MinGW) on x86_64 and x86

  For a complete list of tested systems and compilers, see the INSTALL file.

- GNU Autoconf is still deprecated, running 'configure' emits a warning by
  default.  Support for GNU Autoconf will be removed after this release.

- Updated data dictionary, SOP Class, Frame of Reference and Transfer Syntax
  UIDs for the recently approved changes to the DICOM standard (i.e. Supplements
  and CPs), up to DICOM standard release DICOM 2019c plus Supplement 175 (Second
  Generation Radiotherapy - C-Arm RT Treatment Modalities).

- Added support for directory record "RADIOTHERAPY" that has been introduced
  with Supplement 147 (Second Generation Radiotherapy - Prescription and Segment
  Annotation).

- Added support for the three new 64-bit integer VRs introduced with CP-1819:
  Other 64-bit Very Long (OV), Signed 64-bit Very Long (SV) and Unsigned 64-bit
  Very Long (UV).

- Implemented support for the Extended BCP 195 TLS Profile, introduced with
  Supplement 206, in the dcmtls module and the various TLS-enabled DCMTK tools.

- Added option to "storescu" to rename files after processing them by appending
  ".bad" or ".good" at the end of the filename.

- Added new options to "wlmscpfs" that allow for dumping incoming C-FIND
  requests to text files using a configurable directory and filename.

- Updated automatically generated Context Group classes in "dcmsr"
  (Structured Reporting) based on DICOM 2019c.  Also updated the Code
  definitions from the supported coding schemes such as DICOM, NCIt and UMLS.

- Further enhanced DICOM Structured Reporting (SR) module "dcmsr":

  - Added support for the Performed Imaging Agent Administration SR IOD and the
    Planned Imaging Agent Administration SR IOD introduced with Supplement 164.

  - Added support for the Synchronization Module, which is required for some SR
    IODs, e.g. Procedure Log SR or Performed Imaging Agent Administration SR.

  - Added initial support for coding scheme "SCT" (SNOMED CT) by defining those
    CODE_SCT_xxx code constants that are needed for the "cmr" submodule.

  - Updated SR Template classes from DCMR for the 2019b edition of the DICOM
    standard, i.e. all SRT (SNOMED RT) codes were replaced by their associated
    SCT (SNOMED CT) counterparts. This change was introduced with CP-1850.

  - Added new print flag PF_printEmptyCodes, which prints the text "empty code"
    for empty codes instead of "invalid code". This new flag is e.g. used for
    the output stream operator of the DSRCodedEntryValue class.

- The list of elliptic curves to be negotiated as part of a TLS is now created
  dynamically, i.e. it is tested at runtime which elliptic curves are supported
  by the installed OpenSSL library.

- Allow disabling Functional Group checks when writing Segmentations and
  Parametric Map objects in order to speed up writing objects with many frames.

- Added macro that enables the wide char (wchar_t*) support of the XML parser
  that is part of the DCMTK (ofstd/ofxml). This support is limited to Windows
  systems and still regarded as experimental (see documentation for details).

- The tool "findscu" now always returns with a non-zero exit code when an error
  occurred, e.g. when association negotiation failed.

- CMake-related enhancements:

  - DCMTK now understands and makes use of the CMake variable CMAKE_CXX_STANDARD
    when a CMake version that supports it is employed (CMake 3.1.3 and newer).

  - Added CMake option that controls whether DCMTK gets compiled using the
    multi-threaded static or DLL runtime library when using MSVC on Windows.

- Various fixes and extensions to the JPEG-LS implementation:

  - Added command line options controlling how odd-length bitstreams are
    padded to even length (for compatibility with HP LOCO).

  - Added command line option that causes the decoder to store images even
    though an error occurred during the decoding process, which may be helpful
    for slightly truncated bitstreams.

  - Enable setting of individual JPEG-LS encoding parameters
    T1, T2, T3 and RESET.

  - Various bugfixes in JPEG-LS encoder and decoder.

- Fixed binary Segmentation object creation when width is not dividable by 8.

- Fixed wrong DIMSE status codes A8xx (for C-STORE and C-FIND) and A800 (for
  C-GET and C-MOVE), which were never defined in the official DICOM standard.
  Now, the DCMTK uses the correct DIMSE status code 0122H for "SOP Class not
  supported" for all DIMSE messages.

- Fixed various issues that occurred after the official 3.6.4 release.
  See CHANGES file for details.
