-*   Use a case insensitive URI Regexp for #asset_path.
+*   Fix `Mime::Type.parse` when bad accepts header is looked up. Previously it
+    was setting `request.formats` with an array containing a `nil` value, which
+    raised an error when setting the controller formats.
 
-    This fix a problem where the same asset path using different case are generating
-    different URIs.
+    Fixes #10965
 
-    Before:
+    *Becker*
 
-        image_tag("HTTP://google.com")
-        # => "<img alt=\"Google\" src=\"/assets/HTTP://google.com\" />"
-        image_tag("http://google.com")
-        # => "<img alt=\"Google\" src=\"http://google.com\" />"
+*   Merge `:action` from routing scope and assign endpoint if both `:controller`
+    and `:action` are present. The endpoint assignment only occurs if there is
+    no `:to` present in the options hash so should only affect routes using the
+    shorthand syntax (i.e. endpoint is inferred from the path).
 
-    After:
+    Fixes #9856
 
-        image_tag("HTTP://google.com")
-        # => "<img alt=\"Google\" src=\"HTTP://google.com\" />"
-        image_tag("http://google.com")
-        # => "<img alt=\"Google\" src=\"http://google.com\" />"
+    *Yves Senn*, *Andrew White*
 
-    *David Celis*
+*   ActionView extracted from ActionPack
 
-*   Element of the `collection_check_boxes` and `collection_radio_buttons` can
-    optionally contain html attributes as the last element of the array.
+    *Piotr Sarnacki*, *Łukasz Strzałkowski*
 
-    *Vasiliy Ermolovich*
+*   Fix removing trailing slash for mounted apps #3215
 
-*   Update the HTML `BOOLEAN_ATTRIBUTES` in `ActionView::Helpers::TagHelper`
-    to conform to the latest HTML 5.1 spec. Add attributes `allowfullscreen`,
-    `default`, `inert`, `sortable`, `truespeed`, `typemustmatch`. Fix attribute
-    `seamless` (previously misspelled `seemless`).
-
-    *Alex Peattie*
-
-*   Fix an issue where partials with a number in the filename weren't being digested for cache dependencies.
-
-    *Bryan Ricker*
+    *Piotr Sarnacki*

+== Running with Rake
+
+The easiest way to run the unit tests is through Rake. The default task runs
+the entire test suite for all classes. For more information, checkout the
+full array of rake tasks with "rake -T"
+
+Rake can be found at http://rake.rubyforge.org
+
+== Running by hand
+
+To run a single test suite
+
+   rake test TEST=path/to/test.rb
+
+which can be further narrowed down to one test:
+
+   rake test TEST=path/to/test.rb TESTOPTS="--name=test_something"
+
+== Dependency on Active Record and database setup
+
+Test cases in the test/active_record/ directory depend on having
+activerecord and sqlite installed. If Active Record is not in
+actionview/../activerecord directory, or the sqlite rubygem is not installed,
+these tests are skipped.
+
+Other tests are runnable from a fresh copy of actionview without any configuration.

     *Ben Woosley*
 
+*   `ActiveRecord::Result.each` now returns an `Enumerator` when called without
+     a block, so that it can be chained with other `Enumerable` methods.
+
+    *Ben Woosley*
+
+*   Flatten merged join_values before building the joins.
+
+    While joining_values special treatment is given to string values.
+    By flattening the array it ensures that string values are detected
+    as strings and not arrays.
+
+    Fixes #10669.
+
+    *Neeraj Singh and iwiznia*
+
+*   Do not load all child records for inverse case.
+
+    currently `post.comments.find(Comment.first.id)` would load all
+    comments for the given post to set the inverse association.
+
+    This has a huge performance penalty. Because if post has 100k
+    records and all these 100k records would be loaded in memory
+    even though the comment id was supplied.
+
+    Fix is to use in-memory records only if loaded? is true. Otherwise
+    load the records using full sql.
+
+    Fixes #10509.
+
+    *Neeraj Singh*
+
+*   `inspect` on Active Record model classes does not initiate a
+    new connection. This means that calling `inspect`, when the
+    database is missing, will no longer raise an exception.
+    Fixes #10936.
+
+    Example:
+
+        Author.inspect # => "Author(no database connection)"
+
+    *Yves Senn*
+
+*   Handle single quotes in PostgreSQL default column values.
+    Fixes #10881.
+
+    *Dylan Markow*
+
+*   Log the sql that is actually sent to the database.
+
+    If I have a query that produces sql
+    `WHERE "users"."name" = 'a         b'` then in the log all the
+    whitespace is being squeezed. So the sql that is printed in the
+    log is `WHERE "users"."name" = 'a b'`.
+
+    Do not squeeze whitespace out of sql queries. Fixes #10982.
+
+    *Neeraj Singh*
+
 *   Fixture setup does no longer depend on `ActiveRecord::Base.configurations`.
     This is relevant when `ENV["DATABASE_URL"]` is used in place of a `database.yml`.

 WARNING: You may put your initializer before or after any other initializer in the chain, as long as it is logical. Say you have 4 initializers called "one" through "four" (defined in that order) and you define "four" to go _before_ "four" but _after_ "three", that just isn't logical and Rails will not be able to determine your initializer order.

 ### Adding Fields on the Fly
 
-Rather than rendering multiple sets of fields ahead of time you may wish to add them only when a user clicks on an 'Add new child' button. Rails does not provide any builtin support for this. When generating new sets of fields you must ensure the the key of the associated array is unique - the current javascript date (milliseconds after the epoch) is a common choice.
