Version 2.0.3

Release Date: August 20, 2011

  • Security

    • An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection. An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with mysql_set_charset() creates a situation where using multi-byte character sets on these environments may potentially expose a SQL injection attack vector. Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.

      If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.

  • General Changes

Please note that the old Validation class is now deprecated.
