Are new EnvDTE Assemblies being released?

Hello,

I'd like to know if new EnvDTE assembly versions (Ex EnvDTE110.dll) are planned to be released. Unless I'm mistaken, new assemblies were released for new Visual Studio versions through EnvDTE100 for VS 2010. VS 2012,2013,2015, and 2017 have not seen new EnvDTE assemblies. Has their functionality been superseded by something else? 

Thank you!
