Blacklist is now Blocklist (WP 5.5)

[Zodiac1978]

With the coming WordPress 5.5 the blacklist_keys are changed to blocklist_keys.

See this changeset:
https://core.trac.wordpress.org/changeset/48121

Affected line:

blacklist-updater/inc/blacklist_updater.class.php

Line 128 in 6562e94

'blacklist_keys',

The name of the option has changed in the final version of WordPress 5.5 to disallowed_keys

If this plugin will still be maintained in the future and not added to ASB here is solution for the issue:

		/* Update blocklist */
		if ( false === get_option( 'disallowed_keys' ) ) {
			// WordPress before 5.5.
			update_option(
				'blacklist_keys',
				wp_remote_retrieve_body( $response )
			);
		} else {
			// WordPress 5.5 or higher.
			update_option(
				'disallowed_keys',
				wp_remote_retrieve_body( $response )
			);
		}

Regardless of the inclusion into ASB: the field in the WP backend is called "Blocklist" (already in 5.4). We can't update a blacklist, that doesn't factually exist any longer. Let's rename this plugin

Like I wrote in Slack: The new name is “Disallowed Comment Keys” instead of Blocklist (which was valid in 5.4).

And we can change the name but not the slug:
