Attribute interoperability with 15.1

2015.1 DVCS servers don’t support fetching and pushing of attributes. If you try to push files with attributes from a 2015.1 server to a 2016.1 server, the 2016.1 server will detect that the attribute data was not provided and not include any attributes on the pushed files.

If a 2016.1 server tries to push files with attributes to a 2015.1 server, the 2015.1 server quietly ignores the attributes data.
