Documentation

The NTP implementation documentation for all software versions from 1998 (NTP version 3.5.93e) to the present (NTP version 4.2.8p15) is available from the Documentation drop-down menu.

Most software versions represent a series of patch levels. The landing page for each series has a table showing all patch levels for that series, including release dates and links to release announcements. The documentation for a series applies to all patch levels for that series, unless specified otherwise.

To ensure your system is patched against all known vulnerabilities and has the latest features and bug fixes applied, it is recommended to use the latest series (4.2.8-series) and patch level (p15).
