* PostgreSQL invalid `uuid` are convert to nil.
*Abdelkader Boudih*
-
+
+* Restore 4.0 behavior for using serialize attributes with `JSON` as coder.
+
+ With 4.1.x, `serialize` started returning a string when `JSON` was passed as
+ the second attribute. It will now return a hash as per previous versions.
+
+ Example:
+
+ class Post < ActiveRecord::Base
+ serialize :comment, JSON
+ end
+
+ class Comment
+ include ActiveModel::Model
+ attr_accessor :category, :text
+ end
+
+ post = Post.create!
+ post.comment = Comment.new(category: "Animals", text: "This is a comment about squirrels.")
+ post.save!
+
+ # 4.0
+ post.comment # => {"category"=>"Animals", "text"=>"This is a comment about squirrels."}
+
+ # 4.1 before
+ post.comment # => "#<Comment:0x007f80ab48ff98>"
+
+ # 4.1 after
+ post.comment # => {"category"=>"Animals", "text"=>"This is a comment about squirrels."}
+
+ When using `JSON` as the coder in `serialize`, Active Record will use the
+ new `ActiveRecord::Coders::JSON` coder which delegates its `dump/load` to
+ `ActiveSupport::JSON.encode/decode`. This ensures special objects are dumped
+ correctly using the `#as_json` hook.
+
+ To keep the previous behaviour, supply a custom coder instead
+ ([example](https://gist.github.com/jenncoop/8c4142bbe59da77daa63)).
+
+ Fixes #15594.
+
+ *Jenn Cooper*
+
+* Do not use `RENAME INDEX` syntax for MariaDB 10.0.
+
+ Fixes #15931.
+
+ *Jeff Browning*
+
+* Calling `#empty?` on a `has_many` association would use the value from the
+ counter cache if one exists.
+
+ *David Verhasselt*
+
* Fix the schema dump generated for tables without constraints and with
primary key with default value of custom PostgreSQL function result.
