= New Features
* Database#values has been added on SQLite#3.8.3+, operating similarly
to the support on PostgreSQL:
DB.values([[1, 2], [3, 4]]).select_map([:column1, :column2])
# => [[1, 2], [3, 4]]
* Regular expressions in dataset filters are now supported on Oracle
10g+:
DB[:t].where(:c=>/re/)
# SELECT * FROM "T" WHERE REGEXP_LIKE("C",'re')
= Other Improvements
* Sequel now supports the use of native prepared statements and bound
variables in the mysql2 adapter, when mysql2 0.4+ is used.
Previously, the mysql2 adapter supported database prepared
statements, but variables were always literalized. That is still
supported when mysql2 <0.4 is used.
* The connection pool now removes connections if it detects a
disconnect error that is not raised as a
Sequel::DatabaseDisconnectError. Such exceptions are reraised
without converted them to Sequel::DatabaseDisconnectError, but the
related connection is now removed from the pool.
* The reversible migration support now handles add_constraint with an
options hash as the first argument.
* ASTTransformer now handles Sequel.extract, allowing Dataset#qualify
and other uses of ASTTransformer to work with such values.
* The create_view :columns option is now suppported on SQLite 3.9.0+.
* An additional disconnect error is now recognized in the postgres
adapter.
* A frozen string literal issue has been fixed when multiple different
database connection approaches have failed in the jdbc adapter.
= Backwards Compatibility
* External database adapters need to make sure that
Database#database_error_classes returns a valid result if called
during Database#initialize. If you have an external adapter where
one of the error classes depends on an argument given when
connecting (such as the connection string), you may have to make
some changes.
