Since Azure is offering free hosting for 4.6 webapp, I'm sure you should get back to your roadmap (especially since your upgrade reason (preparing for Core) is more relevant each new day)
(fun story : created a template this morning, trying at noon to update it, and discovering you created a new template 4h hours ago)
Thanks for your work !
I'm a bit surprised at this bit "What’s New? Moved to .NET 4.6.1"
When the templates projects created by the website are 4.5.2
