* Fix galaxy publish sha256 value format.
The multipart/form content used for the body
of the POST to /api/automation-hub/v3/collections
was missing a newline before the line with the value
of the sha256.
automation-hub/galaxy/django skips the field entirely in
that case and automation-hub code will use None for default
to indicate that no sha256 is provided (an available option).
Fixesansible/galaxy-dev#246
* Add changelog fragment
