- Database
+ - Added **dsn** configuration setting for drivers that support DSN strings (PDO, PostgreSQL, Oracle, ODBC, CUBRID).
+ - Added **schema** configuration setting (defaults to *public*) for drivers that might need it (currently used by PostgreSQL and ODBC).
+ - Added subdrivers support (currently only used by PDO).
+ - Added an optional database name parameter to ``db_select()``.
+ - Added a constructor to the ``DB_result`` class and moved all driver-specific properties and logic out of the base ``DB_driver`` class to allow better abstraction.
+ - Removed ``protect_identifiers()`` and renamed internal method ``_protect_identifiers()`` to it instead - it was just an alias.
+ - Renamed internal method ``_escape_identifiers()`` to ``escape_identifiers()``.
+ - Updated ``escape_identifiers()`` to accept an array of fields as well as strings.
+ - MySQL and MySQLi drivers now require at least MySQL version 5.1.
+ - ``db_set_charset()`` now only requires one parameter (collation was only needed due to legacy support for MySQL versions prior to 5.1).
+ - Replaced the ``_error_message()`` and ``_error_number()`` methods with ``error()``, which returns an array containing the last database error code and message.
+ - Improved ``version()`` implementation so that drivers that have a native function to get the version number don't have to be defined in the core ``DB_driver`` class.
+ - Added ``unbuffered_row()`` method for getting a row without prefetching whole result (consume less memory).
+ - Added capability for packages to hold *database.php* config files.
+ - Added MySQL client compression support.
+ - Added encrypted connections support (for *mysql*, *sqlsrv* and PDO with *sqlsrv*).
+ - Removed :doc:`Loader Class <libraries/loader>` from Database error tracing to better find the likely culprit.
+ - Added support for SQLite3 database driver.
+ - Added Interbase/Firebird database support via the *ibase* driver.
+ - Added ODBC support for ``create_database()``, ``drop_database()`` and ``drop_table()`` in :doc:`Database Forge <database/forge>`.
- :doc:`Query Builder <database/query_builder>` changes include:
- Renamed the Active Record class to Query Builder to remove confusion with the Active Record design pattern.
- Added the ability to insert objects with ``insert_batch()``.
