New

Add support for PostgreSQL operator classes to add_index

The operator classes identify database operators to be used by the index for the columns. You can assign the same operator to all columns, or not.
It currently only supports PostgreSQL.

Add ability to create PostgreSQL foreign keys without validation

Normally, PostgresSQL verifies that all rows in a table satisfy its foreign keys constraints. With this option, you can create these constraints without the overhead of checking if they are valid.

Add preload_link_tag helper

The helper creates a link tag with the preload keyword that allows you to basically define resources that pages will need very soon after loading. In addition, Rails will send HTTP2 Early Hints if the proxy server supports it, helping the fetch process.

Improvements

Prevent Active Record scopes with reserved names

An error will be raised when defining scopes with names already defined by ActiveRecord::Relation instance methods.
