Others + will still be available in local_assigns. + + Example of render with reserved words: + + ```erb + <%= render "example", class: "text-center", message: "Hello world!" %> + + <!-- _example.html.erb: --> + <%= tag.div class: local_assigns[:class] do %> + <p><%= message %></p> + <% end %> + ``` + + *Peter Schilling*, *Matthew Draper* + +* Show cache hits and misses when rendering partials. + + Partials using the `cache` helper will show whether a render hit or missed + the cache: + + ``` + Rendered messages/_message.html.erb in 1.2 ms [cache hit] + Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss] + ``` + + This removes the need for the old fragment cache logging: + + ``` + Read fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/d0bdf2974e1ef6d31685c3b392ad0b74 (0.6ms) + Rendered messages/_message.html.erb in 1.2 ms [cache hit] + Write fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/3b4e249ac9d168c617e32e84b99218b5 (1.1ms) + Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss] + ``` + + Though that full output can be reenabled with + `config.action_controller.enable_fragment_cache_logging = true`. + + *Stan Lo* + +* Changed partial rendering with a collection to allow collections which + implement `to_a`. + + Extracting the collection option had an optimization to avoid unnecessary + queries of ActiveRecord Relations by calling `#to_ary` on the given + collection. Instances of `Enumerator` or `Enumerable` are valid + collections, but they do not implement `#to_ary`. By changing this to + `#to_a`, they will now be extracted and rendered as expected. + + *Steven Harman* + +* New syntax for tag helpers. Avoid positional parameters and support HTML5 by default. + Example usage of tag helpers before: + + ```ruby + tag(:br, nil, true) + content_tag(:div, content_tag(:p, "Hello world!"), class: "strong") + + <%= content_tag :div, class: "strong" do -%> + Hello world! + <% end -%> + ``` + + Example usage of tag helpers after: + + ```ruby + tag.br + tag.div tag.p("Hello world!"), class: "strong" + + <%= tag.div class: "strong" do %> + Hello world! + <% end %> + ``` + + *Marek Kirejczyk*, *Kasper Timm Hansen* + +* Change `datetime_field` and `datetime_field_tag` to generate `datetime-local` fields. + + As a new specification of the HTML 5 the text field type `datetime` will no longer exist + and it is recommended to use `datetime-local`. + Ref: https://html.spec.whatwg.org/multipage/forms.html#local-date-and-time-state-(type=datetime-local) + + *Herminio Torres* + +* Raw template handler (which is also the default template handler in Rails 5) now outputs + HTML-safe strings. + + In Rails 5 the default template handler was changed to the raw template handler. Because + the ERB template handler escaped strings by default this broke some applications that + expected plain JS or HTML files to be rendered unescaped. This fixes the issue caused + by changing the default handler by changing the Raw template handler to output HTML-safe + strings. + + *Eileen M.
