    1.4.3
	As there have been additions to the libFLAC interfaces, the libFLAC version
	 number is incremented to 13. The libFLAC++ version number stays at 10.
	* General
		* All PowerPC-specific code has been removed, as it turned out those
		  improvements didn't actually improve anything
		* Large improvements in encoder speed for all presets. The largest
		  change is for the fastest presets and for 24-bit and 32-bit inputs.
		* Small improvement in decoder speed for BMI2-capable CPUs
		* Various documentation fixes and cleanups (Mark Grassi, Jake Schmidt)
		* Various fixes (Ozkan Sezer, Zhipeng Xue, orbea, Sam James, Harish
		  Mahendrakar)
		* Fix building on Universal Windows Platform (Dmitry Kostjučenko)
	* flac
		* A lot of small fixes for bugs found by fuzzing
		* Various improvements to the --keep-foreign-metadata and
		  --keep-foreign-metadata-if-present options on decoding
			* The output format (WAV/AIFF/RF64 etc.) is now automatically
			  selected based on what kind of foreign metadata is stored
			* Decoded file is checked afterwards, to see whether stored
			  foreign format data agrees with FLAC audio properties
			* AIFF-C sowt data can now be restored
		* Add --force-legacy-wave-format option, to decode to WAV with
		  WAVEFORMATPCM where WAVE_FORMAT_EXTENSIBLE would be more appropriate
		* Add --force-aiff-c-none-format and --force-aiff-c-sowt-format to
		  decode to AIFF-C
		* The storage of WAVEFORMATEXTENSIBLE_CHANNEL_MASK is no longer
		  restricted to known channel orderings
		* Throw an error when WAV or AIFF files are over 4GiB in length and
		  the --ignore-chunk-sizes option is not set
		* Warn on testing files when ID3v2 tags are found
		* Warn when data trails the audio data of a WAV/AIFF/RF64/W64 file
		* Fix output file not being deleted after error on Windows
		* Removal of the --sector--align option
	* metaflac
		* A lot of small fixes for bugs found by fuzzing
		* Added options --append and --data-format, which makes it possible to
		  copy metadata blocks from one FLAC file to another
		* Added option --remove-all-tags-except
		* Added option --show-all-tags (harridu, Martijn van Beurden)
	* libFLAC
		* No longer write seektables to Ogg, even when specifically asked for.
		  Seektables in Ogg are not defined
		* Add functions FLAC__metadata_object_set_raw and
		  FLAC__metadata_object_get_raw to convert between blob and
		  FLAC__StreamMetadata
	* Build system
		* Autoconf (configure)
			* The option --enable-64-bit-words is now on by default
		* CMake
			* The option ENABLE_64_BIT_WORDS is now on by default
	* Testing/validation
		* Fuzzers were added for the flac and metaflac command line tools
		* Fuzzer coverage was improved
