v1.3.0

Added

• New Relation#exist? predicate checks if the relation has at least one tuple (flash-gordon)
• Support for JSONB transformations and queries using native DSL (flash-gordon)
• Add ROM::SQL::Attribute#not for negated boolean equality expressions (AMHOL)
• Add ROM::SQL::Attribute#! for negated attribute's sql expressions (solnic)
• Inferrer gets limit constraints for string data types and stores them in type's meta (v-kolesnikov)

Fixed

• Fixed usage of PostgreSQL's commands with a composite relation (flash-gordon)
• Translation of true/false/nil equality checks to is/is not SQL statements in ROM::SQL::Attribute#is (AMHOL)
• associates command plugin coerces parent collections to hashes correctly (aarek+solnic)
• by_pk works correctly even when PK is not projected (solnic)

Changed

• Global private interface SQL::Gateway.instance has been deprecated. Now if you run migrations
  with ROM you should set up a ROM config in the db:setup task with something similar to

    namespace :db
      task :setup do
        ROM::SQL::RakeSupport.env = ROM::Configuration.new(:sql, ENV['DATABASE_URL'])
      end
    end
