Errors with WP 3.9.2

When network activating the plugin or activating on an individual site with a multi-site install of WordPress 3.9.2, I get this error:

“Strict Standards: Non-static method sc_WPUpdatesNotifier::settingsUpToDate() should not be called statically in wp-content/plugins/wp-updates-notifier/wp-updates-notifier.php on line 42 Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method sc_WPUpdatesNotifier::admin_settings_init() should not be called statically in wp-includes/plugin.php on line 470 Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method sc_WPUpdatesNotifier::remove_update_nag_for_nonadmins() should not be called statically in wp-includes/plugin.php on line 470”

When viewing a site with the plugin activated, I get this error:

“Strict Standards: Non-static method sc_WPUpdatesNotifier::settingsUpToDate() should not be called statically in wp-content/plugins/wp-updates-notifier/wp-updates-notifier.php on line 42”

Let me know if I can provide additional detail. It seems this might be the only plugin to send notifications when updates are pending. Thanks.
