Are there significant differences between .NET Core v1 and .NET Core v2?

Question

ASP.NET

I want to buy an ASP.NET Core MVC book with C# examples for professionals, but there, as I understand it, version 1 is being discussed. Does it make sense to buy this book when you already have .NET Core version 2?
Here I found: What's new in ASP.NET Core 2.0
By the way, I found very useful information not only on .NET Core (it is also there)
Documentation on .NET (some of the information is in Russian ...
Added a few days later
People bought the book. The book is fire! Worth the money!
I tried to learn ASP.NET Core MVC on one site where all the components are signed, but there is such a presentation, I barely read a few chapters, it was hard to read. You are constantly distracted when you read on your computer. And as soon as I bought the book, everything fell into place, you read and make examples. Everything is clear, convenient and understandable.

Answer 2

The pace of ASP.Net Core development is crazy. From 1.0 to 2.0 per year. When the 2.0 book comes out, there will already be 3.0 on the horizon. or buy a book, or learn from off-line documentation.
