Main changes/improvements for version 2.2.3:
Special note: To support the new authentication mode 'cookie', there is now a new configuration variable 'auth_type', and 'adv_auth' no longer exists. You can still use http basic authentication. As usual, start from the new config.inc.* file and read the documentation :)
Fixes:
* bug with text and time type fields with the "query by example" feature;
* bug with the database creation form that may be displayed when it shouldn't or may be missing when it should be displayed.
Some improvements:
* multiple tables printable view;
* checkboxes for null values;
* support for OS/2 browsers;
* links to short page of MySQL documentation;
* vertical display mode;
* cookie authentication mode;
* improved dump feature in order to limit timeout or memory out effects;
* some languages were updated.
