New Features¶ ↑

• A deprecated_associations plugin has been added, which supports warning if a deprecated association is used:

  Album.plugin :deprecated_associations
  Album.many_to_one :artist, deprecated: true
  album = Album[1]
  
  # Warnings for all of the following calls
  album.artist
  album.artist_dataset
  album.artist = Artist[2]
  Album.association_reflection(:artist)
  Album.eager(:artist)
  Album.eager_graph(:artist)
  Album.where(artist: Artist[1]).all
  

  You can customize the behavior using the :raise, :deduplicate, and :backtrace plugin options.

• Database#rename_schema has been added on PostgreSQL to support renaming schemas.

Other Improvements¶ ↑

• Database#drop_schema on PostgreSQL now clears all cached schema information.

• Postgres::PGRange#inspect in the pg_range extension now provides more friendly output:

  Sequel::Postgres::PGRange.from_range(1...3, :int4).inspect
  # => "#<Sequel::Postgres::PGRange [1,3)::int4>"
  

• BigDecimal typcasting when using the looser_typecasting extension now works as expected when using newer bigdecimal gem with Ruby < 2.4.
