commands\n  * Add interval option to driftfile directive\n  * Add waitsynced and waitunsynced options to local directive\n  * Add sanity checks for integer values in configuration\n  * Add support for systemd Type=notify service\n  * Add RTC refclock driver\n  * Allow PHC refclock to be specified with network interface name\n  * Don’t require multiple refclock samples per poll to simplify\n    filter configuration\n  * Keep refclock reachable when dropping samples with large delay\n  * Improve quantile-based filtering to adapt faster to larger\n    delay\n  * Improve logging of selection failures\n  * Detect clock interference from other processes\n  * Try to reopen message log (-l option) on cyclelogs command\n  * Fix sourcedir reloading to not multiply sources\n  * Fix tracking
