* |
| 14 |
* A request to add filters on sql queries exists: http://core.trac.wordpress.org/ticket/15202. |
| 15 |
* Method used in 0.4.x: use of the get_calendar filter and overwrite the output of get_calendar function -> not very efficient (add 4 to 5 sql queries). |
| 16 |
* Method used since 0.5: remove the WP widget and replace it by our own -> our language filter will not work if get_calendar is called directly by a theme. |
