## Bug Fixes
* Fixed incorrect reference_date for GONG Synoptic maps. (#7758)
* Fix
:func:`sunpy.physics.differential_rotation.differential_rotate`
to update the reference_date attribute of the input map instead
of the date. (#7758)
* Fixed incorrect reference_date for SDO/AIA and SDO/HMI data to
use the T_OBS keyword instead of the DATE-OBS keyword.
* For AIA images, the location of SDO has been shifted up to a
second in time, which corresponds to a shift in Heliographic
Longitude by only 4 milliarcseconds. (#7758)
- Release 6.0.0
## Breaking Changes
* Arguments for ~sunpy.map.GenericMap.reproject_to after the
target WCS are now keyword-only. (#7339)
* Arguments for sunpy.timeseries.GenericTimeSeries.peek are now
keywords only. (#7340)
* Removed scikit-image from the "image" extra group and created a
new "scikit-image" extra group. (#7536)
* sunpy.io.read_file and sunpy.io.write_file are deprecated and
will be removed in the future. These were intended to be
private functions and should not be used. (#7537)
* The ANA C code has been deprecated (sunpy.io.ana.read,
sunpy.io.ana.get_header, sunpy.io.ana.write) and may be removed
in a future sunpy release. Please contact us here:
https://community.openastronomy.org/t/possible-deprecation-of-ana-file-readers-and-writers-in-sunpy
if you are making use of this code. (#7642)
* The .EUIMap class now returns the DATE-BEG key for
.GenericMap.date while continuing to use DATE-AVG as the
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-sunpy?expand=0&rev=59
