• 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.
