 Change History
 
+2016-05-06 - bug fixes, 2.5.14
+
+ o Release 2.5.12 caused two problems with Atoms and DTS-X wrapping that are
+   addressed by this release. The UL values that were changed to correct the
+   DCData (ST 429-14) implementation had two unintended side-effects:
+     1. v2.5.12 cannot read old DCData (and thus DTS-X) track files
+     2. v2.5.12 creates broken Atmos track files (incorrect ULs)
+   The fix for this involved the following changes:
+     1. ASDCP::DCData::(MXFReader|MXFWriter) are no longer base classes of
+        ASDCP::ATMOS::(MXFReader|MXFWriter).
+     2. New UL values have been added to carry the original Atoms UL values:
+        a. DolbyAtmosDCDataWrappingFrame
+        b. DolbyAtmosDCDataEssence
+        c. DolbyAtmosDCDataDescriptor
+     3. ASDCP::ATMOS::(MXFReader|MXFWriter) have been modified to use the
+        DolbyAtmosDCData* UL values.
+     4. ASDCP::DCData::MXFReader will parse files having either DCData* or
+        DolbyAtmosDCData* UL values.
+     5. ASDCP::DCData:: MXFWriter continues to use DCData* UL values from ST
+        429-14
+  o Some optional parameters of the MXF metadata packs were being erroneously
+    initialized with a value of zero (0), such as GenericPictureEssenceDescriptor
+    ::SignalStandard, GenericPictureEssenceDescriptor::SampledXOffset(0), etc.
+  o Added higher edit rates (96, 100, 120) to the cinema TimedText_Parser
+
+  o Defined bool ASDCP::UL::operator<(const UL& rhs) const, which is needed to
+    carry out the version-insensitive lookup policy when searching for ULs in a
+    std::map<> of UL entries.
+  o New files:  src/info.in src/CMakeLists.txt
+  o Removed filess:  AS_DCP_DCData_internal.h
+
+
+2016-03-17 - bug fixes, 2.5.12
+ o Changed default UNIX file permissions to "666"
+ o Changed default UNIX file permissions to "777"
+ o Added missing initializer for caltime::offset
+ o Fixed UL values for Aux Data files (per ST 429-14)
+ o Added support for default TTML fonts (ST2052_TextParser)
+ o Added Solaris patch to KM_fileio (Thanks Mikey!)
+ o Fixed the version byte in UL DataEssenceCoding
+ o Fixed duplicate linkage error for symbol MIME2str
+ o Big patch from Wolfgang Ruppel:
+   o Corrected erroneous fixed-tag values in ActiveHeight, ActiveWidth,
+     ActiveXOffset, ActiveYOffset UL definitions.
+   o Provided a stub implementation for Kumu::DirScannerEx (A real
+     implementation will follow soon.)
+   o Added as-02-info program
+   o Added Seek() method to PCM parsers
+   o Added CMakeLists.txt
+
+
+2015-11-10 - bug fixes, IMF text, pink noise, 2.5.11
+ o I moved personal dev environment from older gcc to newer clang.  Many
+   small changes were made to satisfy the new compiler:
+   - Altered many printf format codes to use the correct format for the
+     given integer type.
+   - Parenthesized some expressions to clarify previously ambiguous
+     expectation about precedence.
+   - Created macro KM_MACOSX for use in OS-specific code selection.
+   - Removed last uses of the old C-language abs(), now using Kumu::xabs().
+   - Removed last uses of the old C-language atoi(), not using strtol().
+ o Added platform-independent call Kumu::GetExecutablePath() (to be tested
+   on win32).
+ o Added new capabilities to Result_t.
+ o Added imlementation of SMPTE ST 2092-1 pink noise generator.
+ o Added pinkwave CLI utility.
+ o Added font support to the IMF timed-text wrapper.
+ o Fixed a bug that was causing Array properties to be written without
+   the (count, length) header (from PAL).
+ o General review of Batch/Array distinction throughout the project.
+ o Cleaned up definitions of optional properties in all MXF metadata packs.
+ o Fixed Win32 build (from Crowe).
+ o Fixed a bug that caused incorrect failure when parsing JPEG 2000
+   codestreams having fewer than five decomposition levels. (from Korneder).
+ o Fixed missing UUID generation in some instances of the MCALinkID property.
+ o Added -w option to asdcp-wrap to support use of WTF label with MCA.
+ o Altered asdcp-wrap to recognize "-C <UL>" when MCA is being used.
+ o Fixed broken -A <w>/<h> option in as-02-wrap and phdr-wrap.
+ o asdcp-wrap and as-02-wrap now allow split channel groups in MCA labels.
+
+
+2015-02-23 - bug fixes, 2.4.10
+  o Fixed a new bug introduced by the fix to large numbers of subtitle ancillary
+    resources.
+  o Added support for generic Aux Data (ST 429-14) to asdcp-wrap.
+
+
+2015-02-19 - PHDR feature, bug fixes, 2.4.9
+  o Modified PCMParser and PCMParserList to return partial frame buffers at the
+    end of a WAV input file.  This was needed to allow wrapping all samples into
+    an AS-02 audio file (which is clip-wrapped) in the case where the input file
+    has an odd number of samples with respect to the frame buffer size being
+    used.  If there is more than one input file the length of the last buffer
+    will be determined by PCMParserList to be the shortest of the input files.
+    Prior to this change, partial samples in an input WAV file have been
+    abandoned (i.e., not written out to the MXF file).  As a result, AS-DCP
+    applications will have to decide whether to abandon the partial last frame
+    (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
+    or write it to the MXF file.  Programs written to the old API will write the
+    partial frame (i.e., new behavior.)  This should not be harmful since the
+    remainder of the buffer is zeroed and the output file will contain one
+    additional edit unit compared to the previous version.
+  o asdcp-wrap has been modified to test for the partial buffer and by default
+    will complain and abandon the buffer (i.e., same behavior but with a warning
+    message.)  A new command line switch (-g) alters this behavior and writes
+    the buffer to the MXF file (it still warns the user that this condition is
+    present.)
+  o as-02-wrap now wraps all samples from the input file to the MXF file. There
+    is no padding, the clip is exactly the set of samples from the input.
+  o as-02 unwrap is temporarily restricted to creating wav files that are
+    aligned with the frame buffer size.  This means that the output file will
+    be longer than the original WAV input in the case where the input file has
+    an odd number of samples with respect to the frame buffer size being used.
+    The pad samples are zero (silence).
+  o Modified CalcFramesFromDurationInSamples() to increment the count by one for
+    the case where the input file has an odd number of samples with respect to
+    the frame buffer size being used (previously it truncated the odd samples.)
+  o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
+    resources are present (fixes a bug that cause the header to overflow the
+    allotted space when large numbers of PNG files were present.)
+  o Refactored GetXMLDocType() to use the XML parser.
+  o Added ParseFirstFromString() method to Kumu::XMLElement
+  o Removed Kumu::StringIsXML from the API.
+  o Added ASDCP::MXF::RGBALayout type
+  o Added J2CLayout property to JPEG2000PictureSubDescriptor
+  o Changed km_token_split() to retain empty elements in the output list
+  o Added PHDR wrapping for AS-02.
+  o Added J2CLayout property to the JPEG2000PictureSubDescriptor.  This
+    support is preliminary: the Raw data type is being used instead of
+    RGBALayout type, which will be in the next release.
+
+
+2014-10-2 - Bug fixes and enhancements, 2.2.6
+  o Fixed erroneous 377-4 MCA identifier in AS_DCP_PCM dump routine
+  o Fixed erroneous byte 13 in
+    WaveAudioDescriptor_ReferenceAudioAlignmentLevel label
+  o Added missing implementation of -W option to as-02.unwrap
+  o Fixed erroneous use of d-cinema ChannelAssignment label in as-02-wrap
+
+
+2014-10-01 - Bug fixes and enhancements, 2.2.5
+  o Finished AS-02 text wrap/unwrap
+  o Fixed fractional seconds parsing for Timestamp objects
+  o Updated KLVPacket to use 64-bit length; allows huge packets
+    in AS-02 PCM files
+  o cleaned up use of atoi() in the library
+
+
+2014-07-09 - Additional IMF/AS-02 support, bug fixes and enhancements, 2.1.4
+  o Added IMF App 2 edit rates in AS_02 namespace: EditRate_29_97, 
+    EditRate_59_94. 
+  o Revised AEC CBC context objects to copy the key rather than  
+    keep the reference passed in to it.
+  o Addressed a bug that would allow unimpeded iteration of component 
+    values in a JP2K::PictureDescriptor object.
+  o Addressed a bug that was incorrectly recording the sequence Duration 
+    in MXF Track objects.
+  o Added ASDCP::AtmosSyncChannelMixer::AppendSilenceChannels()
+  o Added a QCD decoder to the j2c parser.
+  o Altered ASDCP::KLVPacket::HasUL() to use version-blind matching.
+  o Fixed an uninitialized variable in MemIOReader::ReadString() that  
+    caused unbounded reads.
+  o Fixed broken ByteString::ArchiveLength() method
+  o Fixed broken version numbers on SoundfieldGroupLinkID and  
+    GroupOfSoundfieldGroupsLinkID UL values.
+  o Added DBOXMotionCodePrimaryStream and DBOXMotionCodeSecondaryStream UL 
+    values to the internal dictionary.
+  o Added optional prefix handling to MCA label generator.
+  o Re-factored MCA label generator to include additional  
+    metadata (Thanks to Mike Radford).
+  o Added new options to as-02-wrap.
+
+
+2014-01-06 – Additional IMF/AS-02 support, bug fixes 2.1.1
+  o Fixed missing-index-partion bugs for AS-02 files.
+  o Moved LocalFilenameResolver into the AS_DCP public API so that it
+    can be used by other modules including AS-02.
+  o Did further refactoring of AS-02 Writer classes to separate CBR
+    and VBR indexing implementations.
+  o Fixed wave wrapping UL in clip-wrapped AS-02 files.  Renamed some
+    UL constants to reflect "clip" or "frame" wrapping.
+  o Re-factored JP2K_PDesc_to_MD() and MD_to_JP2K_PDesc() to work
+    with GenericPictureEssenceDescriptor objects.
+  o Fixed a bug that was suppressing PictureComponentSizing,
+    CodingStyleDefault and QuantizationDefault when writing the
+    essence descriptor in a JP2K file (AS-DCP and AS-02).
+  o Fixed the version byte on the following UL values:
+    	  StereoscopicPictureSubDescriptor
+	  GenericPictureEssenceDescriptor_ColorPrimaries
+	  GenericPictureEssenceDescriptor_ActiveHeight
+	  GenericPictureEssenceDescriptor_ActiveWidth
+	  GenericPictureEssenceDescriptor_ActiveXOffset
+	  GenericPictureEssenceDescriptor_ActiveYOffset
+  o Added some essence descriptor options to as-02-wrap.
+  o Changed bit rate display in asdcp-info from mebi-bits/s to
+    mega-bits/s.
+  o Added "SMPTE" / "Interop" format type display to asdcp-info.
+  o Improved integration of ST 377-4 MCA concepts with ST 429-2 static
+    labels.
+  o Modified asdcp-wrap to assume -L when wrapping timed-text (since
+    there is no MXF text wrapping for Interop.)
+  o Added new EssenceType_t values for IMF/AS-02 track files.
+  o Added detection for AS-02 track files to ASDCP::EssenceType()
+  o Changed lots of "const char*" to "const std::string&" in the
+    APIs defined by KM_fileio.h and AS_DCP.h.
+  o Fixed VBR Delta Segment entries to correctly flag progressive
+    material.
+  o Fixed PCM unwrapping bugs in as-02-unwrap.
+  o Fixed missing return statement in ArchivableString::ArchiveLength
+    (thanks to both Kristof Provost and Franck Chopin) 
+  o Fixed broken sample alignment in RF64Writer (thanks to Wolfgang
+    Woehl and Dolby)
+  o Fixed win32 build (thanks to Dolby)
+  o fixed a bug that caused blackwave to only produce 96kHz WAV files.
+    (thanks to Stephane W)
+
+
+2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
+  o Massive refactoring of internals to allow easier implementation
+    of AS-02.  Some API changes were made as well (note that
+    OPAtomHeader is now OP1aHeader and RIP is no longer part of the
+    OP1aHeader.)  If you are using this project as a library (and
+    especially if you are keeping patches against it) PLEASE TAKE
+    TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
+    YOUR RELEASE PATH.
+  o Final integration of Fraunhoffer IIS code contribution.  AS-02
+    files are now fully supported with some TODOs and two major
+    exceptions: LEAD indexes are not supported by the MXF writers
+    and interlace images are not yet supported.
+  o Added support for MCA labels (ST 428-12) to asdcp-wrap.  Note
+    that this project is still in the early stages of interop testing
+    so errors are likely present and don't expect any server to
+    make use of this feature.
