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 render work.Go 1.6 introduces a new block 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.
