 0.4 was released. from the
 [http://aubio.org/news/20131217-1900_aubio_0.4.0.html announcement]:

 After more than five years of development behind the curtain, the time has
 come to release a new version of aubio.

 The list of changes is long, but to make it short, aubio is now:

     - more portable: with no required dependencies, the core of aubio
 library, written in ANSI C, is known to compile and run on most modern
 platforms (Linux, Windows, Mac OS X, Android, iOS, ...).
     - more stable: several bugs fixes and a battery of tests make this new
 release more robust and less prone to errors.
     - faster: several enhancements to the C library and a brand new Python
 interface help make this release orders of magnitude faster than the
 previous ones.

 Several new features have been added, including:

     - the new source object uses libav to read audio samples from any
 audio or video file, compressed or uncompressed, including over different
 network protocol. (On Apple systems, decoding of most audio formats is
 also possible using CoreAudio).
     - a new filterbank object, completely customizable, allows for
 computing energies in any number of custom designed spectral bands.
     - a new mfcc object computes the Mel Frequency Cepstrum Coefficients
 (MFCC). It is implemented according to Malcom Slaney's Auditory Toolbox.
     - new spectral descriptors, including statistics such as centroid,
 skewness, slope, decrease, rolloff, and kurtosis.
     - new simple synthesis objects provide basic ways of generating sounds
