This reverts commit f7de647f2cd099ecf6434fa4a0db1ec297f1c32d.

We can't deprecate things in stable branches. I didn't not realized that
the pull request was for 3-2-stable
Add 3.2.9 section in ARes CHANGELOG

[ci skip]
Bump to 3.2.9.rc1
fixed support for DATABASE_URL for rake db tasks

Backport for #7521

- added tests to confirm establish_connection uses DATABASE_URL and
  Rails.env correctly even when no arguments are passed in.
- updated rake db tasks to support DATABASE_URL, and added tests to
  confirm correct behavior for these rake tasks.  (Removed
  establish_connection call from some tasks since in those cases
  the :environment task already made sure the function would be called)
- updated Resolver so that when it resolves the database url, it
  removes hash values with empty strings from the config spec (e.g.
  to support connection to postgresql when no username is specified).
- updated ResolverTest to use current_adapter? to check the type of
  the current adapter.
Merge pull request #8009 from graceliu/3-2-fix_database_url_support

fixed support for DATABASE_URL for rake db tasks
Fix bug when Column is trying to type cast boolean values to integer.

This can occur if the user is using :integer columns to store boolean
values. Now we are handling the boolean values but it still raises if
the value can't type cast to integer and is not a boolean. See #7509.

Fixes #8067.
Fix typo :bomb: [ci skip]

Revert "Merge pull request #7797 from senny/7459_prefix_tempalte_assertion_variables"

This reverts commit 2bad605873b5b720d77ae6388a995827ab7fe705.

Conflicts:
	actionpack/CHANGELOG.md

Reason: This added a regression related with shoulda-matchers, since it
is expecting the instance variable @layouts

See https://github.com/thoughtbot/shoulda-matchers/blob/9e1188eea68c47d9a56ce6280e45027da6187ab1/lib/shoulda/matchers/action_controller/render_with_layout_matcher.rb#L74

This will introduce back #7459 but this stable release will be backward compatible.
Related with #8068.

Fix ActiveRecord#update_column return value
Merge pull request #8083 from saks/fix_update_column_return_value

Fix ActiveRecord#update_column return value
relaxes assertion

This method returns the status of the operation,
but as we generally do in the code base it does
not commit to any particular exact value. Hence,
we do not have to check for a singleton, because
if the implementation changes and returns some
other true value the test should pass.
