 ## [x.x.x] - xxxx-xx-xx
 ## Added
 - Implemented support for certificate profile selection
+- Added a configuration parameter to allow for timeouts during order processing (`ORDER_TIMEOUT`, defaults to 0 = no timeout)
 
 ## Changed
 - Renew certificates with 32 days remaining (instead of 30) to avoid issues with monthly cronjobs (`RENEW_DAYS=32`)
