==================================
- No functional source code changes.
- Fixed some compiler warnings.
- Rebuilt the fpcalc binaries with FFmpeg 4.4.1.
- Added support for fat binaries on macOS, with support for both Intel and Apple silicon.
Version 1.5.0 -- April 15, 2020
===============================
- Added support for fpcalc -raw -signed, which helps with easier PostgreSQL integration
- Added support for using libavresample instead of libswresample
- Fixed possible crash in chromaprint_decode_fingerprint
- Fixed unit tests on big endian CPUs
Version 1.4.3 -- January 21, 2018
==================================
- Allow one packet to have decoding error
- Print output even if there is a decoding error, exit with error code 3 instead of 2 in such case
- Add new option -ignore-errors to change the error code 3 to 0
- Add new option -algorithm NUM
- Periotically flush output when working on a stream
Version 1.4.2 -- December 28, 2016
==================================
- Fixed invalid memory access when decoding base64-encoded fingerprints.
- Removed unnecessary library dependencies libchromaprint to avoid circular dependency problems with FFmpeg.
Version 1.4.1 -- December 12, 2016
==================================
- Restored the -v/-version parameter for fpcalc that got accidentally removed in 1.4.
- Fixed processing of some short audio files. They were ignored in 1.4.
- The DURATION field in the default output of fpcalc is now printed as an integer again.
- Added missing version number to libchromaprint.pc.
- Mac OS X fpcalc builds are done with clang/libc++ and should work on 10.7+.
- Linux fpcalc builds are now fully static.
Version 1.4 -- December 3, 2016
===============================
- Fully streaming audio processing without any post-processing step for the fingerprint generation.
- Many performance optimizations. Especially when processing long streams, operations should be faster and use less memory.
- C++11 compiler is now required for building the library.
- The public C API now uses standard fixed-size int types from stdint.h (breaks backwards compatibility).
- All code written for the library is now distributed under the MIT license.
- Kiss FFT is now included with the library and automatically used if no other FFT library is found.
- Added support for using the FFTW3F version of FFTW3.
- Boost is no longer used.
Version 1.3.2 -- July 9, 2016
=============================
- Fixed crash on an invalid audio file that FFmpeg could not decode.
- Fixed build on Ubuntu 14.04 with libav.
Version 1.3.1 -- February 10, 2016
==================================
- Fixed `fpcalc -length` to actually restrict fingerprints the requested length.
- Fixed SONAME version for the shared library.
Version 1.3 -- February 2, 2016
===============================
- You can use use "-length 0" in fpcalc to get the full fingerprint
- New function chromaprint_get_fingerprint_hash for calculating
SimHash from the fingerprint data
- Added info section to the fpcalc executable on Mac OS X
- Generate .pc (pkg-config) file on Mac OS X when not building a framework
- Removed use of some long deprecated FFmpeg APIs
- Some smaller bug fixes
Version 1.2 -- August 26, 2014
==============================
- Fixed compilation with neither libswresample nor libavresample (#11)
- Fixed compilation with static libav (#10)
- Functions chromaprint_encode_fingerprint and chromaprint_decode_fingerprint
are changed to accept const pointer as input
- Added support for using the Kiss FFT library (should make Android port easier)
- Removed obsolete dev tools from the package
- More compatible DEBUG() macro
Version 1.1 -- November 23, 2013
================================
- Fixed potential DoS attack in fingerprint decompression code. (#6)
- Fixed invalid memory read with some fingerprinter configurations. (#5)
- Fixed compilation with clang on OS X 10.9 (#7, #9)
- Added support for audio format conversion with libav. (#2, Gordon Pettey)
Version 1.0 -- September 7, 2013
================================
- Support for the latest FFmpeg API.
- Support for reading audio from stdin in fpcalc.
- Changed fpcalc to return non-zero status on failure.
Version 0.7 -- September 5, 2012
================================
- Support for the latest FFmpeg API.
- New (non-default) fingerprint algorithm that removes leading silence.
- API to configure fingerprint algorithms, currently only used by
CHROMAPRINT_ALGORITHM_TEST4.
Version 0.6 -- December 22, 2011
================================
- Support for 24-bit file formats in fpcalc.
- The fpcalc utility now uses 120 seconds of audio data by default.
- Python bindings moved to a separate project (pyacoustid).
Version 0.5 -- October 6, 2011
==============================
- Unicode command line handling in fpcalc.
- Fixed a crash in fpcalc when FFmpeg was not able to identify the codec.
- Added encode_fingerprint to the Python bindings.
Version 0.4 -- May 14, 2011
===========================
- Support for building a Mac OS X framework.
- Support for building a static library.
- Simple C example (fpcalc) that can be used from external applications for
fingerprint calculations.
Version 0.3 -- April 26, 2011
=============================
- Fixed compilation with MSVC 2010.
- Added support for calculating FFT using the Accelerate framework on
Mac OS X and iOS.
- Added Python bindings.
Version 0.2 -- January 26, 2011
===============================
- New public functions chromaprint_{encode,decode}_fingerprint to
encoding/decoding raw fingerprints.
- New public function chromaprint_dealloc that should be used for
releasing all memory allocated in Chromaprint functions.
