New Features¶ ↑

• The jdbc/mysql adapter now supports the newer com.mysql.cj.jdbc.Driver driver. The adapter will still attempt to load the older com.mysql.jdbc.Driver if the com.mysql.cj.jdbc.Driver is not found.

Other Improvements¶ ↑

• When testing a connection after creating a new Database instance raises an exception, the Database instance is removed from Sequel::DATABASES.

• The single_table_inheritance and prepared_statements plugins now work correctly if loaded into the same class.

• Database connect and disconnect errors are no longer swallowed when calling Database#create_or_replace_view, Database#server_version on PostgreSQL, or Database#create_table* on Oracle.

Backwards Compatibility¶ ↑

• Previously, instantiating a new Database instance directly using Sequel::Database.new did not test the connection by default. That was instead handled by Sequel::Database.connect. The test connection now happens inside Database#initialize. This should only affect backwards compatibility for code that is calling Sequel::Database.new directly.
