+ Matroska: cover presence and content of the cover, thanks to Max Pozdeev
+ #F446, Matroska: Handling of cropping values, thanks to Max Pozdeev
+ Improvement of Python binding: Mac Os X support, Python2 and Python3 can use \ 
same MediaInfoDLL.py
+ #F484, AVI: OpenDML Interlaced / Progressive scan type detection
+ MP4: support of AtomicParsley imdb tag
x #B959, MPEG-TS: MPEG-1 Video appeared as MPEG-2 Video
x #B914, Matroska: Undefined number of chapters in some M4V with Timed Text, \ 
thanks to Max Pozdeev
x #B962, Matroska: negative timecodes were not correctly handled
x #B964, FLV: was hanging trying to open some FLV files
x JPEG in AVI or MOV: better handling of buggy APP0/AVI1, avoiding some false \ 
positives about interlacement
x DVCPRO HD: some containers consider DVCPRO HD as with width 1920 despite the \ 
fact it is 1280 or 1440, using 1280 or 1440 in all cases

Version 0.7.80, 2015-11-30
--------------
+ Matroska: support of MKVMerge statistics tags (duration frame count, stream \ 
size, bit rate) per track, thanks to ndjamena
+ FLAC: Channel positions, thanks to ndjamena
+ FLAC: difference between detected bit depth and stored bit depth
+ MPEG-TS: if DTVCC transport stream is present and no DTVCC service descriptor, \ 
scan also in the middle of the file in order to detect more caption services
+ Subtitle frame rate computing if frame count and duration are available \ 
(hidden by default)
+ Subtitles in Matroska: count of elements
+ Matroska, MXF and MP4/MOV: detection of truncated files
+ DTS: difference between ES Matrix and ES Discrete
+ DTS: display ES Matrix or ES Discrete even if HRA or MA is present
+ DTS: difference between DTS-HRA with 96k option and pure DTS-96/24
+ DTS: detection of DTS:X
+ Samples per frame info
+ AC-3: detection of Atmos inside TrueHD
+ Video frame rate: showing precision of 1/1.001 frame rates (e.g. "23.976 \ 
(24000/1001) fps" and "23.976 (23976/1000) fps")
+ MPEG-4/MOV: showing the complete list of compatible brands in the CodecID field
+ MPEG-4/MOV: Alternate groups
+ MPEG-4/MOV: "Disabled" tag
+ MPEG-4/MOV: "Forced" tag
+ MPEG-4/MOV: showing links between tracks (chapters for, subtitles for, \ 
fallback for)
+ MXF: handling of more acquisition metadata items
+ MXF: Package name
+ AVC: Store method of interlaced content (Interleaved Fields or Separated Fields)
+ EBUCore: acquisition metadata (Proof of concept, for feedback only)
x Matroska: frame rate detection algorithm revisited, less wrong numbers are expected
x SDP/Teletext: some pages were sometimes (when present in 2 different SDP \ 
lines) displayed several times
x MPEG-4/MOV: some hint tracks were not displayed

Version 0.7.79, 2015-11-02
--------------
+ CLI/DLL only, XML: new option --Output=MIXML, with XML v2.0beta1 status, not \ 
for production, see https://github.com/MediaArea/MediaAreaXml for more details
+ MediaTrace: support of more than 1 file in XML output.
+ CLI/DLL only, XML: new option --Output=MAXML, with XML v0.1 status, in order \ 
to have bot MediaInfo and MediaTrace in the same output, not for production, see \ 
https://github.com/MediaArea/MediaAreaXml for more details
x MediaTrace: fixed some invalid outputs
x #B951, Amazon S3 support (REST API v2), CLI/DLL only and if compiled with \ 
libcurl support: URL without credential were badly interpreted

Version 0.7.78, 2015-10-02
--------------
+ MOV: AVrp CodecID support
+ Video Stored_Width/Stored_Height and Sampled_Width/Sampled_Height added \ 
(hidden by default)
+ Speed optimization for the parsing of tiny files e.g. JPEG files
+ Option (command line / DLL) --Legacy=0 for disabling some legacy fields
+ Option (command line / DLL) --Output=MAXML, XML with MediaInfo and MediaTrace \ 
output together, technology preview (not for production)
x MPEG-TS: Teletext and Teletext Subtitle were missing in the menu list
x Chroma subsampling "4:4:4" was sometimes indicated for RGB, which is \ 
not useful
