This issue only happens on master due to internal AR refactorings, so
there is no need for a changelog entry.
The test was backported to 3-2-stable to ensure there won't be any regressions.
Pending work on graceful app upgrades.

in the new 'variables:' hash in each database config section in database.yml.
The key-value pairs of this hash will be sent in a 'SET key = value, ...'
query on new database connections.
The configure_connection methods from mysql and mysql2 into are
consolidated into the abstract_mysql base class.
The real win with these chain methods is where.not, that takes care of
different scenarios in a graceful way, for instance when the given value
is nil.
where("author.id != ?", author_to_ignore.id)
where.not("author.id", author_to_ignore.id)
Both where.like and where.not_like compared to the SQL versions doesn't
seem to give us that much:
Post.where("title LIKE 'ruby on%'")
Post.where.like(title: 'ruby on%'")
Post.where("title NOT LIKE 'ruby on%'")
Post.where.not_like(title: 'ruby on%'")
Thus Rails is adding where.not, but not where.like/not_like and others.
Relation.where with no args can be chained with not, like, and not_like

When applying default_scope to a class with a where clause, using
update_column(s) could generate a query that would not properly update
the record due to the where clause from the default_scope being applied
to the update query.
class User < ActiveRecord::Base
default_scope where(active: true)
end
user = User.first
user.active = false
user.save!
user.update_column(:active, true) # => false
In this situation we want to skip the default_scope clause and just
update the record based on the primary key. With this change:
user.update_column(:active, true) # => true
Fixes#8436.
Sometimes, on Mac OS X, programmers accidentally press Option+Space
rather than just Space and don’t see the difference. The problem is
that Option+Space writes a non-breaking space (0XA0) rather than a
normal space (0x20).
This commit removes all the non-breaking spaces inadvertently
introduced in the comments of the code.
examples:
Model.where.not field: nil
#=> "SELECT * FROM models WHERE field IS NOT NULL
Model.where.like name: 'Jeremy%'
#=> "SELECT * FROM models WHERE name LIKE 'Jeremy%'

Allows you to do BaseClass.new(:type => "SubClass") as well as
parent.children.build(:type => "SubClass") or parent.build_child
to initialize an STI subclass. Ensures that the class name is a
valid class and that it is in the ancestors of the super class
that the association is expecting.
To perform a sum calculation over the array of elements, use to_a.sum(&block).

This was there due historical reasons since
7dc45818dc43c163700efc9896a0f3feafa31138 to give the user the
possibility to create unique indexes passing "UNIQUE" as the third
argument
Public method `attributes_before_type_cast` used to return internal AR structure (ActiveRecord::AttributeMethods::Serialization::Attribute), patch fixes this. Now behaves like `read_attribute_before_type_cast` and returns unserialised values.
