8. GENERAL DB IMPROVEMENTS
- Added an optional parameter that allows to disable escaping (useful for custom
fields) for methods join(), order_by(), where_in(), or_where_in(), where_not_in(),
or_where_not_in().
- Added support for join() with multiple conditions.
- Added support for USING in join().
- Changed limit() to ignore NULL values instead of always casting to integer.
- Changed offset() to ignore empty values instead of always casting to integer.
- Added 'dsn' configuration setting for drivers that support DSN strings (PDO,
PostgreSQL, Oracle, ODBC, CUBRID).

9. MYSQLI DB IMPROVEMENTS
- OOP style of the PHP extension is now used, instead of the
procedural aliases.
- Server version checking is now done via MySQLi::$server_info
instead of running an SQL query.
- Added persistent connections support for PHP >= 5.3.

10. PDO GOT SOME BALLS

11. CACHING
Redis + Wincache = YAY!

12. OUTPUT MINIFICATION
$config['minify_output'] = TRUE;

13. PAGINATION + SEARCH
CodeIgniter 1.x & 2.x
/search/results/2
CodeIgniter 3.0:
$config[‘reuse_query_string’] = TRUE;
/search/results/2?q=business
/search/results?q=business&filter[blog]=blog:posts

14. PROPER EMPTY VALUES
CodeIgniter 1.x & 2.x
$foo = $this->input->post(‘dunno’);
var_dump($foo); // FALSE
CodeIgniter 3.0:
$foo = $this->input->post(‘dunno’);
var_dump($foo); // NULL

15. CSRF TWEAKS
Invalid Messages no more
$config['csrf_regeneration'] = TRUE;
Exclude URIs
$config['csrf_exclude_uris'] = array('paypal/confirm');

16. FAILOVER DB CONNECTIONS
$db['default']['failover'] = array(
array(
'hostname' => 'foo.com',
'username' => '',
'password' => '',
'database' => '',
'dbdriver' => 'mysqli',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'autoinit' => TRUE,
),
array(
//...
),
);

17. PHP 5.2.4
Old things are old, and sometimes that is ok.

18. EVERYONE LOVES CALLBACKS
$route['products/([a-z]+)/edit/(d+)'] =
function($product_type, $id)
{
return "catalog/product_edit/" . strtolower($product_type) .
"/" . $id;
};
