 # Render [![GoDoc](http://godoc.org/github.com/unrolled/render?status.svg)](http://godoc.org/github.com/unrolled/render) [![Test](https://github.com/unrolled/render/workflows/Test/badge.svg?branch=v1)](https://github.com/unrolled/render/actions)
 
 
-Render is a package that provides functionality for easily rendering JSON, XML, text, binary data, and HTML templates. This package is based on the [Martini](https://github.com/go-martini/martini) [render](https://github.com/martini-contrib/render) work.
-
-## Block Deprecation Notice
-Go 1.6 introduces a new [block](https://github.com/golang/go/blob/release-branch.go1.6/src/html/template/example_test.go#L128) action. This conflicts with Render's included `block` template function. To provide an easy migration path, a new function was created called `partial`. It is a duplicate of the old `block` function. It is advised that all users of the `block` function update their code to avoid any issues in the future. Previous to Go 1.6, Render's `block` functionality will continue to work but a message will be logged urging you to migrate to the new `partial` function.
+Render is a package that provides functionality for easily rendering JSON, XML, text, binary data, and HTML templates.
 
 ## Usage
 Render can be used with pretty much any web framework providing you can access the `http.ResponseWriter` from your handler. The rendering functions simply wraps Go's existing functionality for marshaling and rendering data.
