+
+2009.03.08 - SMPTE format fixes, enhancements and bug fixes, v.1.4.21
+ o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
+ generation when environment variable KM_USE_RANDOM_UUID is defined.
+ o Fixed a condition that could cause an error to occur whenwrapping
+ SMPTE format timed text track files that do not define a starting
+ frame.
+ o Updated ULs for SMPTE format track files.
+ o SampleRate added to JP2K metadata
+ o Support for wrapping 96kHz WAV files added.
+ o Updated ULs for audio channel formats (ChannelFormat)
+ o Updated font subdescriptor MIME Types for TimedText Trackfiles.
+ o Changed time implementation to support dates beyond Jan 19th, 2038.
+ o Xerces-C XML parser support added.
+ o New build method for Windows (see win32/README.txt for details).
+
+
+2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
+ o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
+ o Exposed JP2K metadata parser as ParseMetadataIntoDesc().
+ o Added simple stereoscopic framebuffer to support paired ReadFrame()
+ and WriteFrame() methods (allows simpler integration with other
+ single-buffer code).
+ o Improved detection of JPEG Interop stereoscopic files.
+ o Win32 build fixes (Thanks to Mike Crowe at DTS).
+ o Added the WITH_MD macro to the makefile. Set this value to one
+ to build Win32 with /MD[d] instead of /MT[d].
+ o The Generic Container UL has been added to the EssenceContainers
+ set in the header partition pack for encrypted files. It has always
+ been there in plaintext files.
+ - Below this point the changes are internal and should not affect you
+ unless you use Kumu directly.
+ o Major refactoring of KM_log.[h|cpp].
+ o Fixed buffer re-sizing issue in Kumu::ByteString.
+ o Replaced type IdentifierList with ArchivableList.
+ o Added COPYING file to the release bundle.
+
+
+2007.12.13 - Bug fixes v.1.2.17
+ o Changed Result_t implementation to use int instead of long, which
+ was causing trouble on some 64 bit platforms.
+ o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
+ Interop files. To validate these files, use asdcplib-1.1.14. This
+ should not cause too much trouble since files with broken and
+ non-broken HMAC have been in the wild for years without issue.
+ o Fixed HMAC sequence numbering in encrypted stereoscopic files.
+ o Finished stereoscopic test targets in the makefile.
+ o Fixed the win32 build, now expects VS2005 compiler by default,
+ use WITH_VC6=1 top get VC6 flags.
+ o Stereoscopic and Timed Text modes now have SMPTE UL values.
+ NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
+ that these UL values may change before publication. Please use
+ caution when using these features for production work.
+ o Changed a bunch of symbol names in the 429-5 implementation to
+ better match the spec.
+ o Added -U option to asdcp-test to dump the UL library to stdout.
+ o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
+ files (Interop and SMPTE modes).
+
+
+2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
+ o Significant API changes have been made. Please read all entries
+ in this changelog to be sure you understand the changes. Also
+ note that some changes have been made to LS_MXF_SMPTE files that
+ are incompatible with earlier releases (e.g., EKLV HMAC). If
+ you are looking for a stable interop release, use v.1.1.14.
+ o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
+ broken implementation has been maintained for Interop mode.
+ o Added support for draft SMPTE 429-5 Timed Text Track File. This
+ is still waiting for official SMPTE ULs, so do not use it for
+ shipping products. An XML parser is needed to create a Timed
+ Text Track File; Expat is now an optional part of the build.
+ Make with WITH_XML_PARSER=1 to link with Expat. If you do not
+ link with expat, you will get an error when using the TimedText::
+ DCSubtitleParser class. See also S429-5-cgi.cpp for an example
+ that shows how to serve plaintext MXF file elements directly via
+ HTTP.
+ o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
+ File, including the JPEG Interop version. This is still waiting
+ for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
+ shipping products.
+ o Refactored the following files as a side-effect of the above
+ work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp
+ AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp]
+ Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.cpp.
+ WARNING: While significant effort has been extended to make sure
+ that these changes do not affect existing stable file support,
+ users are cautioned to test this release thouroughly.
+ o Added a large set of filesystem path manglers to KM_fileio.h. See
+ path-test.cpp for example usage. The path manglers have not yet
+ been tested on win32 platforms (they are currently used only by
+ the Timed Text module.
+ o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
+ have been modified to accept const std::string& instead of
+ const char*.
+ o Added namespace and parsing support (Expat) to Kumu::XMLElement
+ (currently used only for Timed Text support). Also added some
+ new accessors.
+ o Altered MXF::UTF16String to use mbtowc() and wctomb().
+
+
+2007.03.31 - Bug fixes v.1.1.14
+ o Fixed KeyFrameOffset value in MPEG wrapping to have negative
+ value. This is probably not yet complete for handling all
+ types of GOPs. Please send chunks of MPEG-2 VES that you
+ find which break this. Thanks to Doremi.
+ ** no other file format changes in this release **
+ o Fixed error in RIP interpretation when reading arbitrary (i.e.,
+ non-MXF) files.
+ o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
+ in read mode. Thanks to Mahesh Bajaj for pointing out this
+ bug and the one above.
+ o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
+ return value statements.
+ o Added -s and -p to the makefile install target.
+ o Altered ByteString behavior to use target Length() in copy
+ operations (instead of Capacity()).
+ o Added new Set() method to ByteString.
+ o Fixed a bug in ByteString::Unarchive() that caused the operation
+ to fail when the buffer was smaller than the read (i.e., when
+ Capacity() was called).
+ o Added IdentifierList class to KM_util.h.
+ o Changed some Error() messages to Debug() in Wav.cpp
+ o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
+ stale #includes).
+
+
+2007.02.15 - Bug fixes v1.1.13
+ o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
+ from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
+ o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
+ KM_log.h. These versions log the location of the null value.
+ Macros are now used in any module that includes KM_log.h.
+ o MPEG2 VES with run of zero values at the head is now OK.
+ o Increased VESHeaderBufSize to 16K.
+ o Added makefile support for local OpenSSL in ../openssl, if
+ present.
+ o The Kumu::PathIs*() functions now return false if a null or
+ empty string is given (used to be an assert).
+ o Cleaned up the install target in the makefile.
+ o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
+ laughably incorrect. Thanks to Doremi for pointing this out.
+ o Removed default parameter to HMACContext::InitKey().
+ o Cleaned up messages and CLI arg handling in asdcp-test.
