For the license that you used to get as part of the silver core these have been replaced under the M365 E3 license you now get. Previously you would have had Office 365 E3, Enterprise Mobility + Security, MS Intune and Windows 10 Enterprise.
Not sure that for silver and Mid Market Cloud Solutions you ever got Windows 10 Enterprise, but you did get EMS + Security E3 and Office 365 E3 that have also now been removed and replaced with M365 Business Premium + Business Voice.
All the benefits can be found on the competency benefits table that also lists the recent changes. https://assetsprod.microsoft.com/mpn-maps-software-iur-competency-license-table.docx
