Microsoft 365 Enterprise was renamed from Secure Productive Enterprise in August 2017. There are some helpful licensing resources: an at-a-glance document and overview/FAQ document, but most usefully a Licensing Brief where you’ll find an overview of the products in Microsoft 365 Enterprise, the types of User SL available, as well as licensing scenarios and FAQs.
Find all of these documents here: http://bit.ly/MSLicensingGuides.
Microsoft update the August 2017 Product Terms and Online Services Terms with the name change of Secure Productive Enterprise to Microsoft 365 Enterprise. There are no changes to the licensing.
The Enterprise Cloud Suite will automagically change into Secure Productive Enterprise on 1st October 2016.
SPE will be available in two flavours – E3 and E5 – and ECS becomes SPE E3. However, it also gets some new rights including the ability to install the server software for Exchange, Skype for Business and SharePoint on on-premises servers for SPE users (useful if you need to deploy further servers on your way to the cloud) and the From SA USLs also include the rights to install Office Professional Plus on one device.

Microsoft give some more detail on the Secure Productive Enterprise plans which will replace the Enterprise Cloud Suite.
Firstly, there’s news that licensed users will be allowed one on-premises install of Office Professional Plus, and then there’s confirmation that SPE E3 and E5 will be available through the EA and MPSA at launch in the fourth quarter of 2016, and then later through CSP too.
