  • Sample data now downloads automatically on import if not available and is now pluggable so can be used by affiliated packages. Shortcut names have been normalized and all LIGHTCURVE shortcuts have changed to TIMESERIES.
  • Calculation of points on an arc of a great circle connecting two points on the Sun.
  • Maps from Helioviewer JPEG2000 files now have correct image scaling.
  • Removed extract_time function from sunpy.time and also tests related to the function from sunpy.time.tests
  • User can now pass a custom time format as an argument inside sunpy.database.add_from_dir() in case the date-obs metadata cannot be read automatically from the files.
  • Get and set methods for composite maps now use Map plot_settings.
  • Simplified map names when plotting.
  • Add time format used by some SDO HMI FITS keywords
  • Fix bug in wcs.convert_data_to_pixel where crpix[1] was used for both axes.
  • Fix some leftover instances of GenericMap.units
  • Fixed bugs in sun equations
  • Now the sunpy.database.tables.display_entries() prints an astropy table.
  • Additional methods added inside the sunpy.database class to make it easier to display the database contents.
  • sunpy.io.fits.read will now return any parse-able HDUs even if some raise an error.
  • VSOClient no longer prints a lot of XML junk if the query fails.
  • Remove unused sunpy.visualization.plotting module
  • Port the pyana wrapper to Python 3
  • Map.peek(basic_plot=True) no longer issues warnings
  • Remove the sunpy.map.nddata_compat module, this makes Map.data and Map.meta read only.
  • Add a NorthOffsetFrame class for generating HGS-like coordinate systems with a shifted north pole.
  • Remove deprecated VSOClient.show method.
  • Deprecate sunpy.wcs: sunpy.coordinates and sunpy.map now provide all that functionality in a more robust manner.
  • Added hdu index in sunpy.database.tables.DatabaseEntry as a column in the table.
  • Removed HelioviewerClient from the sunpy.net namespace. It should now be imported with from sunpy.net.helioviewer import HelioviewerClient.
  • Removed compatibility with standalone wcsaxes and instead depend on the version in astropy 1.3. SunPy now therefore depends on astropy>=1.3.
  • Update to TimeRange.__repr__; now includes the qualified name and id of the object.
  • A new sunpy.visualization.imageanimator.LineAnimator class has been added to animate 1D data. This has resulted in API change for the sunpy.visualization.imageanimator.ImageAnimator class. The updateimage method has been renamed to update_plot.
  • Change the default representation for the Heliographic Carrington frame so Longitude follows the convention of going from 0-360 degrees.
  • Fix Map parsing of some header values to allow valid float strings like 'nan' and 'inf'.
  • Drop support for Python 3.4.
  • SunPy now requires WCSAxes and Map.draw_grid only works with WCSAxes.
  • Helioprojective and HelioCentric frames now have an observer attribute which itself is a coordinate object (SkyCoord) instead of B0, L0 and D0 to describe the position of the observer.
  • GenericMap.draw_grid now uses WCSAxes, it will only work on a WCSAxes plot, this may be less performant than the previous implementation.
  • GenericMap.world_to_pixel and GenericMap.pixel_to_world now accept and return SkyCoord objects only.
  • GenericMap has a new property observer_coordinate which returns a SkyCoord describing the position of the observer.
  • GenericMap.submap now takes arguments of the form bottom_left and top_right rather than range_a and range_b. This change enables submap to properly handle rotated maps and take input in the form of SkyCoord objects.
  • When referring to physical coordinates Pair.x has been replaced with SpatialPair.axis1. This means values returned by GenericMap now differentiate between physical and pixel coordinates.
  • Fix Map parsing of some header values to allow valid float strings like 'nan' and 'inf'.
  • The physical radius of the Sun (length units) is now passed from Map into the coordinate frame so a consistent value is used when calculating distance to the solar surface in the HelioprojectiveFrame coordinate frame.
  • A new sunpy.visualization.imageanimator.ImageAnimatorWCS class has been added to animate N-Dimensional data with the associated WCS object.
  • Moved Docs to docs/ to follow the astropy style

  • Removed old sunpy.util.goes_flare_class()
  • Bug fix for RHESSI summary light curve values.
  • The MapCube.as_array function now returns a masked numpy array if at least one of the input maps in the MapCube has a mask.
  • Map superpixel method now respects maps that have masks.
  • Map superpixel method now accepts numpy functions as an argument, or any user-defined function.
  • Map superpixel method no longer has the restriction that the number of original pixels in the x (or y) side of the superpixel exactly divides the number of original pixels in the x (or y) side of the original map data.
