ALE connection between S/4HANA Finance and ECC availability?

Hello, Guys:

I have one question about the availability of ALE connection between S/4HANA Finance (aka, Simple Finance) and remote ECC systems, is it still supported in new release will be delivered in May 2016? and for both directions? and how about the connection between S/4HANA and ECC?

Can you please help to clarify? Thank you in advance.

BR, Lawrence
