Changes for 0.98.x
==================
+* Modified :func:`matplotlib.mlab.psd`, :func:`matplotlib.mlab.csd`,
+ :func:`matplotlib.mlab.cohere`, and :func:`matplotlib.mlab.specgram`
+ to scale one-sided densities by a factor of 2. Also, optionally
+ scale the densities by the sampling frequency, which gives true values
+ of densities that can be integrated by the returned frequency values.
+ This also gives better MatLab compatibility. The corresponding
+ :class:`matplotlib.axes.Axes` methods and :mod:`matplotlib.pyplot`
+ functions were updated as well.
+
* Font lookup now uses a nearest-neighbor approach rather than an
exact match. Some fonts may be different in plots, but should be
closer to what was requested.
This was sent by the SourceForge.net collaborative development platform, the
world's largest Open Source development site.
