yeah sorry however I would actually use go version 1 as a reference.
everything before was changing just too often, there was go fix however still many changes. also everything before 1.0 wasn&#x27;t targeted too much about performance.
also I can remember how much the template spec changed. thats what I used these days quite heavily. I have a book about go that dates 2011, and I think that was go 0.7 as far as I remember.
