SunPy 0.6.4

[Stuart Mumford]

Hello,


After a week of fighting with conda packages, I can announce the release
of the next bug fix version of SunPy 0.6.x: 0.6.4.

This bug-fix release has the following changes:

* Bug fix for rhessi summary lightcurve values.
* Fix docstring for `pixel_to_data` and `data_to_pixel`.
* Fix the URL for the Helioviewer API. (This fixes Helioviewer.)
* Fix the way `reshape_image_to_4d_superpixel` checks the dimension of
the new image.
* Fix Map to allow `astropy.io.fits Header` objects as valid input for
meta arguments.
* Prevent helioviewer tests from checking access to API when running
tests in offline mode.


You can install this release from pip or conda, and update from a
previous SunPy installation as follows:


pip install -U sunpy


conda update sunpy


Thanks,

Stuart
