 #### Updates
 
-* `pipe_notify(flag = tools::SIGTERM)` will now raise the signal with a 100ms grace period to allow a process to exit normally (#212).
+* `pipe_notify(flag = tools::SIGTERM)` will now raise the signal with a 200ms grace period to allow a process to exit normally (#212).
 * `parse_url()` drops 'rawurl', 'host' and 'requri' from the output vector as these can be derived from the other parts.
