 The following events are available:
 
+* `check_url_before_add` (`function($url) -> Url | null`): will be executed every time a URL is added. The URL itself will be passed as parameter. This way a website known to have feeds which doesn't advertise it in the header can still be automatically supported.
 * `entry_before_display` (`function($entry) -> Entry | null`): will be executed every time an entry is rendered. The entry itself (instance of FreshRSS\_Entry) will be passed as parameter.
 * `entry_before_insert` (`function($entry) -> Entry | null`): will be executed when a feed is refreshed and new entries will be imported into the database. The new entry (instance of FreshRSS\_Entry) will be passed as parameter.
+* `feed_before_actualize` (`function($feed) -> Feed | null`): will be executed when a feed is updated. The feed (instance of FreshRSS\_Feed) will be passed as parameter.
 * `feed_before_insert` (`function($feed) -> Feed | null`): will be executed when a new feed is imported into the database. The new feed (instance of FreshRSS\_Feed) will be passed as parameter.
 * `freshrss_init` (`function() -> none`): will be executed at the end of the initialization of FreshRSS, useful to initialize components or to do additional access checks
 * `menu_admin_entry` (`function() -> string`): add an entry at the end of the "Administration" menu, the returned string must be valid HTML (e.g. `<li class="item active"><a href="url">New entry</a></li>`)
