[SciPy-User] ANN: PyWavelets 0.5.1 Release

Gregory Lee
Dear all,

On behalf of the PyWavelets development team I am pleased to announce the
release of PyWavelets 0.5.1.

This is a bug-fix only release with no new features as compared to 0.5.0.

PyWavelets is a Python toolbox implementing both discrete and continuous
wavelet transforms (mathematical time-frequency transforms) with a wide
range of built-in wavelets.  C/Cython are used for the low-level routines,
enabling high performance.  Key Features of PyWavelets are:

  * 1D, 2D and nD Forward and Inverse Discrete Wavelet Transform (DWT and
IDWT)
  * 1D, 2D and nD Multilevel DWT and IDWT
  * 1D and 2D Forward and Inverse Stationary Wavelet Transform
  * 1D and 2D Wavelet Packet decomposition and reconstruction
  * 1D Continuous Wavelet Transform
  * When multiple valid implementations are available, we have chosen to
maintain consistency with MATLAB's Wavelet Toolbox.

Bugs Fixed
==========

In release 0.5.0 the wrong edge mode was used for the following three
deprecated mode names: ``ppd``, ``sp1``, and ``per``.  All deprecated edge mode
names are now correctly converted to the corresponding new names.

One-dimensional discrete wavelet transforms did not properly respect the
``axis`` argument for complex-valued data.  Prior to this release, the last
axis was always transformed for arrays with complex dtype.  This fix affects
``dwt``, ``idwt``, ``wavedec``, ``waverec``.
