+*   Use `display:none` instead of `display:inline` for hidden fields
+
+    Fixes #6403
+
+    *Gaelian Ditchburn*
+
+*   The `video_tag` helper accepts a number as `:size`
+
+    The `:size` option of the `video_tag` helper now can be specified
+    with a stringified number. The `width` and `height` attributes of
+    the generated tag will be the same.
+
+    *Kuldeep Aggarwal*
+
+*   A Cycle object should accept an array and cycle through it as it would with a set of
+    comma-separated objects.
+
+        arr = [1,2,3]
+        cycle(arr) # => '1'
+        cycle(arr) # => '2'
+        cycle(arr) # => '3'
+
+    Previously, it would return the array as a string, because it took the array as a
+    single object:
+
+        arr = [1,2,3]
+        cycle(arr) # => '[1,2,3]'
+        cycle(arr) # => '[1,2,3]'
+        cycle(arr) # => '[1,2,3]'
+
+    *Kristian Freeman*
+
+*   Label tags generated by collection helpers only inherit the `:index` and
+    `:namespace` from the input, because only these attributes modifies the
+    `for` attribute of the label. Also, the input attributes don't have
+    precedence over the label attributes anymore.
+
+    Before:
+
+        collection = [[1, true, { class: 'foo' }]]
+        f.collection_check_boxes :options, collection, :second, :first do |b|
+          b.label(class: 'my_custom_class')
+        end
+
+        # => <label class="foo" for="user_active_true">1</label>
+
+    After:
+
+        collection = [[1, true, { class: 'foo' }]]
+        f.collection_check_boxes :options, collection, :second, :first do |b|
+          b.label(class: 'my_custom_class')
+        end
+
+        # => <label class="my_custom_class" for="user_active_true">1</label>
+
+    *Andriel Nuernberg*
+
+*   Fixed a long-standing bug in `json_escape` that causes quotation marks to be stripped.
+    This method also escapes the \u2028 and \u2029 unicode newline characters which are
+    treated as \n in JavaScript. This matches the behaviour of the AS::JSON encoder. (The
+    original change in the encoder was introduced in #10534.)
+
+    *Godfrey Chan*
+
+*   `ActionView::MissingTemplate` includes underscore when raised for a partial.
+
+    Fixes #13002.
+
+    *Yves Senn*
+
+*   Use `set_backtrace` instead of instance variable `@backtrace` in ActionView exceptions
+
+    *Shimpei Makimoto*
+
+*   Fix `simple_format` escapes own output when passing `sanitize: true`
+
+    *Paul Seidemann*
+
+*   Ensure `ActionView::Digestor.cache` is correctly cleaned up when
+    combining recursive templates with `ActionView::Resolver.caching = false`.
+
+    *wyaeld*
+
+*   Fix `collection_check_boxes` generated hidden input to use the name attribute provided
+    in the options hash.
+
+    *Angel N. Sciortino*
+
+*   Fix some edge cases for AV `select` helper with `:selected` option.
+
+    *Bogdan Gusiev*
+
+*   Ability to pass block to `select` helper
+
+        <%= select(report, "campaign_ids") do %>
+          <% available_campaigns.each do |c| -%>
+            <%= content_tag(:option, c.name, value: c.id, data: { tags: c.tags.to_json }) %>
+          <% end -%>
+        <% end -%>
+
+    *Bogdan Gusiev*
+
+*   Handle `:namespace` form option in collection labels.
+
+    *Vasiliy Ermolovich*
+
+*   Fix `form_for` when both `namespace` and `as` options are present.
+
+    `as` option no longer overwrites `namespace` option when generating
+    html id attribute of the form element.
+
+    *Adam Niedzielski*
+
+*   Fix `excerpt` when `:separator` is `nil`.
+
+    *Paul Nikitochkin*
+
+*   Only cache template digests if `config.cache_template_loading` is true.
+
+    *Josh Lauer*, *Justin Ridgewell*
+
+*   Fixed a bug where the lookup details were not being taken into account
+    when caching the digest of a template - changes to the details now
+    cause a different cache key to be used.
+
+    *Daniel Schierbeck*
+
+*   Added an `extname` hash option for `javascript_include_tag` method.
+
+    Before:
+
+        javascript_include_tag('templates.jst')
+        # => <script src="/javascripts/templates.jst.js"></script>
+
+    After:
+
+        javascript_include_tag('templates.jst', extname: false )
+        # => <script src="/javascripts/templates.jst"></script>
+
+    *Nathan Stitt*
+
+*   Fix `current_page?` when the URL contains escaped characters and the
+    original URL is using the hexadecimal lowercased.
+
+    *Rafael Mendonça França*
+
+*   Fix `text_area` to behave like `text_field` when `nil` is given as
+    value.
+
+    Before:
+
+        f.text_field :field, value: nil #=> <input value="">
+        f.text_area :field, value: nil  #=> <textarea>value of field</textarea>
+
+    After:
+
+        f.text_area :field, value: nil  #=> <textarea></textarea>
+
+    *Joel Cogen*
+
+*   Element of the `grouped_options_for_select` can
+    optionally contain html attributes as the last element of the array.
+
+        grouped_options_for_select(
+          [["North America", [['United States','US'],"Canada"], data: { foo: 'bar' }]]
+        )
+
+    *Vasiliy Ermolovich*
+
+*   Fix default rendered format problem when calling `render` without :content_type option.
+    It should return :html. Fix #11393.
+
+    *Gleb Mazovetskiy* *Oleg* *kennyj*
+
+*   Fix `link_to` with block and url hashes.
+
+    Before:
+
+        link_to(action: 'bar', controller: 'foo') { content_tag(:span, 'Example site') }
+        # => "<a action=\"bar\" controller=\"foo\"><span>Example site</span></a>"
+
+    After:
+
+        link_to(action: 'bar', controller: 'foo') { content_tag(:span, 'Example site') }
+        # => "<a href=\"/foo/bar\"><span>Example site</span></a>"
+
+    *Murahashi Sanemat Kenichi*
+
+*   Fix "Stack Level Too Deep" error when redering recursive partials.
+
+    Fixes #11340.
+
+    *Rafael Mendonça França*
+
+*   Added an `enforce_utf8` hash option for `form_tag` method.
+
+    Control to output a hidden input tag with name `utf8` without monkey
+    patching.
+
+    Before:
+
+        form_tag
+        # => '<form>..<input name="utf8" type="hidden" value="&#x2713;" />..</form>'
+
+    After:
+
+        form_tag
+        # => '<form>..<input name="utf8" type="hidden" value="&#x2713;" />..</form>'
+
+        form_tag({}, { :enforce_utf8 => false })
+        # => '<form>....</form>'
+
+    *ma2gedev*
+
+*   Remove the deprecated `include_seconds` argument from `distance_of_time_in_words`,
+    pass in an `:include_seconds` hash option to use this feature.
+
+    *Carlos Antonio da Silva*
+
+*   Remove deprecated block passing to `FormBuilder#new`.
+
+    *Vipul A M*
+
+*   Pick `DateField` `DateTimeField` and `ColorField` values from stringified options allowing use of symbol keys with helpers.
+
+    *Jon Rowe*
+
+*   Remove the deprecated `prompt` argument from `grouped_options_for_select`,
+    pass in a `:prompt` hash option to use this feature.

+
+    Before:

+        link_to_unless(true, '<b>Showing</b>', 'github.com')
+        # => "&lt;b&gt;Showing&lt;/b&gt;"
+
+    *dtaniwaki*

+    different URIs.
+
+    Before:
+
+        image_tag("HTTP://google.com")
