================================================================================
SPy 0.15.0
================================================================================
Release date: 2014.06.04

New Features
------------

* Added Minimum Noise Fraction (`mnf`) algorithm (a.k.a., Noise-Adjusted
Principal Components). An associated `noise_from_diffs` function enables
estimation of image noise from a homogeneous region of the image.


Changes
-------

* When calling `envi.save_image`, assume an ndarray with two dimensions is
a single-band image (i.e., don't require an explicit third dimension).

* [Issue #9] All SpyFile subclass read methods now have an optional
`use_memmap` argument to indicate whether the memmap interface should be
used (vice direct file read) on a per-call basis. Default values are
specific to the particular method and file interleave.

Bug Fixes
---------

* [Issue #7] Handle recognize comment lines in ENVI headers and accept blank
parameter values in the header. Thanks to Don March (http://ohspite.net)

* [Issue #2] Garbage results were being generated for several algorithms when
a NaN value was present in the image data. Reasonable checks are now
performed in several algorithms and an optional `allow_nan` argument (False
by default) was added to `calc_stats`.

* [Issue #1] For images with more rows than columns, the row/col of the pixel
under the mouse cursor did not display if the row index was greater than
the image width.


Performance Improvements
------------------------

* [Issue #5] Improved BilFile.read_bands performance. Thanks to Don March
(http://ohspite.net)

* [Issue #8] Faster creation/display of RGB images for display. Thanks to
Don March (http://ohspite.net)
