Sunpy

=====

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

- Added TimeUTime class to support utime. [2409]
- Example for fine-grained use of ticks and grids [2435]
- Maintiners Workflow Guide [2411]
- Decorator to append and/or prepend doc strings [2386]
- Adding ``python setup.py test --figure-only`` [2557]
- Fido.fetch now accepts pathlib.Path objects for path attribute.[2559]
- The `~sunpy.coordinates.HeliographicStonyhurst` coordinate system can now be specified
using a cartesian system, which is sometimes known as the
"Heliocentric Earth equatorial" (HEEQ) coordinate system. [2437]

API Changes
-----------

- ``sunpy.coordinates.representation`` has been removed. Longitude wrapping is now done in the constructor of the frames. [2431]
- Propagation of ``obstime`` in the coordinate frame transformation has changed, this means in general when transforming directly between frames (not `~astropy.coordinates.SkyCoord`) you will have to specify ``obstime`` in more places. [2461]
- Transforming between Heliographic Stonyhurst and Carrington now requires that ``obstime`` be defined and the same on both the input and output frames. [2461]
- Removed the figure return from .peek() [2487]

- The documentation build now uses the Sphinx configuration from sphinx-astropy rather than from astropy-helpers.[2494]
- Migrate to hypothesis.strategies.datetimes [2368]
- Prevent a deprecation warning due to truth values of Quantity [2358]
- Print a warning when heliographic longitude is set to it's default value of 0 [2480]

Bug Fixes
---------
