From the changelog:
```
Version 0.7.76, 2015-08-06
+ XML output: line breaks and indents in between attributes for readability
+ Trace feature: XML trace update, only if compiled with trace feature
+ Amazon S3 support (REST API v2), CLI/DLL only and if compiled with
libcurl support
+ FFV1: improved slice analysis (currently activated only with trace
feature and for 1st frame)
x MXF: optimization of the parsing, reading a lot less data (e.g. can be
reduced from 1 GB to 10 MB with some UHD files)
x MXF: wrong frame count with files not having the video stream as the
first stream
x Dolby E in MPEG-TS: "SMPTE ST 302" information was accidentally removed
x MPEG-TS: avoid filling delay from file name, not applicable on MPEG-TS
x MXF: better handling of huge padding blocks, better handling of
descriptors without link to a TrackID
x IMX: streams claiming that they are IMX are actually pure MPEG Video,
probing both IMX and MPEG Video
```
Changelog:
```
Version 0.7.75, 2015-06-30
+ MXF: consideraing 60 fps timecode tracks with 2 components having a difference of 2 frames as a single timecode
+ EBUCore 1.6: switch to the link of the final XSD
x XDCAM: some directory structures were wrongly detected as XDCAM structure having a XML file
x MXF: SDTI 60 fps times were wrong
x #B927, DPX: date/time specific DPX format was used instead of the ISO-like one
x #B927, EBUCore: invalid content in attribute startDate
x ProRes: streams with apcs CodecID were displayed with an incoherent bit depth instead of no bit depth

From the mediainfo ChangeLog:
```
Version 0.7.74, 2015-05-25
+ FIMS: Preliminary version (not for production)
+ D-10 audio: display of real bitrate beside the encoded bitrate
+ VC-3: detection of CDP packets (608/708 captions), created by Nexio, inside the VC-3 private data
+ AES3: generic term AES3 replaced by more precise SMPTE ST numbers (302, 331, 337)
+ NUT: basic detection
+ FFV1: more parsing of the bitstream, support of any version of FFV1 in MOV and Matroska
+ DPX: color space and frame rate
x #B906, Matroska: duration was missing if Info block is at the end of the file
x #B908, AC-3: bit depth removed
x #P86, MPEG-4: moov_trak_edts_elst Atom was ignoring version of the atom
x Dolby E: the MXF channel count value was sometimes reported instead of the real channel count
x VorbisComment: WAVEFORMATEXTENSIBLE_CHANNEL_MASK "0X" ("x" in uppercase) is accepted now
x EBUCore: TotalProgrammeDuration was wrongly filled with IdentClockStart value
x EBUCore: Source/Material moved from timecodeStart to timecodeTrack
x MPEG-4: info is missing for some streams in some specific cases

+ MediaInfoDLL interface: Giant threads lock removed
+ #F460, VC-3/DNxHD: detection of RGB 444 and other SMPTE ST 2019 (2014) new CIDs
+ VC-3/DNxHD: version number (HVN)
+ Clean aperture size is move from width/height to its own field
+ HEVC: tier
+ MXF: writing library and writing application fields are cleaned up
+ ProRes: support of 4444 profiles
+ CAP: detection of CAP files from Cheetah and Lambda
x B886, XML and HTML outputs were broken
x B902: EBU AspectRatio invalid in case of non classic numerator:denominator format
x #B758, VC-3/DNxHD: wrong color space and subsampling in case of unknown CID, now empty if format version is not known
x #B903, MXG: Incorrect timecode track used for AS-11 DPP MXF files
x #B904, MXF: Handling repetition of Header Metadata in MXF files
x MXF: AFD value was wrong (displaying the complete byte, but AFD is only 4 bits of this byte)
x DTS: some streams in Little endian were not detected
x MPEG-4: some files were having an incorrect frame count
x AVC: Some SCTE 128 caption streams were displayed twice
x BMP; accepting files with file size information set to -1
x RF64: samplesCount was not always right
x MOV: avoid wrong parsing in case of "colr" atom with "prof" color parameter type
