Chromaprint 1.5.1

• 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.

Chromaprint 1.5.0

• 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

Chromaprint 1.4.3

• 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
• Periodically flush output when working on a stream

Chromaprint 1.4.2

• Fixed invalid memory access when decoding base64-encoded fingerprints.
• Removed unnecessary library dependencies libchromaprint to avoid circular dependency problems with FFmpeg.

Chromaprint 1.4.1

• 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.

Chromaprint 1.4

• 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.
