6.0.3.rc1

Active Support

• Array#to_sentence no longer returns a frozen string.

  Before:

  ['one', 'two'].to_sentence.frozen?
  # => true
  

  After:

  ['one', 'two'].to_sentence.frozen?
  # => false
  

  Nicolas Dular

• Update ActiveSupport::Messages::Metadata#fresh? to work for cookies with expiry set when ActiveSupport.parse_json_times = true.

  Christian Gregg

Active Model

• No changes.

Active Record

• Recommend applications don't use the database kwarg in connected_to

  The database kwarg in connected_to was meant to be used for one-off scripts but is often used in requests. This is really dangerous because it re-establishes a connection every time. It's deprecated in 6.1 and will be removed in 6.2 without replacement. This change soft deprecates it in 6.0 by removing documentation.

  Eileen M. Uchitelle

• Fix support for PostgreSQL 11+ partitioned indexes.

  Sebastián Palma

• Add support for beginless ranges, introduced in Ruby 2.7.

  Josh Goodall

• Fix insert_all with enum values

  Fixes #38716.
