1.2.3 - 2024-07-22

Fixed

  • Metrics exporter should wait for an actual request before sending a response

1.2.2 - 2024-07-18

Changed

  • Updated dependencies

Fixed

  • Fixed a bug in network change detection that prevented startup on FreeBSD.
  • Fixed a bug in leap second flag handling where previous flags weren't explicitly unset.
  • Fixed a bug that caused NTS-KE sessions from clients with a large request to hang.
  • Fixed a bug that caused NTS-KE error records never to be sent.

1.2.0 - 2024-07-11

Added

  • Pool mode sources can be set up to ignore some addresses returned by the pool

  • The MSRV was raised to 1.70
  • The metrics exporter is better able to handle multiple simultaneous connections
  • Pendulum is now part of Trifecta Tech Foundation (copyright was updated)
  • Large parts of the daemon code have been refactored to simplify the code

Fixed

  • Metrics would not synchronize if the metrics data was too large
  • ntpd-rs would ignore responses from servers implementing NTPv3

1.1.3 - 2024-06-28

Fixed

  • Unlimited number of NTS-KE connections could crash ntpd-rs server (CVE-2024-38528)

1.1.2 - 2024-02-01

Fixed

  • Fixed tests in ntp-proto to also work outside the repository.

1.1.1 - 2024-01-24

Added

  • A work in progress implementation for experimental NTS pools was added

Changed

  • Updated dependencies

Fixed

  • Fixed missing newline at the end of the prometheus metrics export
  • Fixed error handling on NTS key exchange sessions
  • Small fixes to the experimental NTPv5 draft support

1.1.0 - 2023-11-23

Added

  • Server can now be run without permission to change the system clock so long as no time sources are configured.
  • Experimental NTPv5 draft support was added behind a feature flag (disabled by default)

Changed

  • The sources section can be left out of the configuration now.
  • When no sources are configured, the daemon will merely state it won't change system time, rather than warn
  • The MSRV was raised to 1.67

1.0.0 - 2023-10-05

Added

  • Man pages have been added to the built packages.
  • ntp-ctl now has human-friendly output
  • Added metrics for NTS packets processed in the server
  • Exposed root dispersion and root delay reported by time source as metrics.
  • Added ntp_uptime_seconds metric, which also includes the software version

Changed

  • Peers have been renamed to sources.
  • The configuration has been completely reworked, please check the documentation for details. Configuration will not automatically migrate.
  • The metrics for observation have been completely reworked.
  • Several changes have been made to reduce the number of dependencies.
  • Send software timestamping is now enabled by default.
  • Hardware timestamping can now only be configured if ntpd-rs is built with the hardware-timestamping feature (off by default).
  • The default observation socket path was changed to /var/run/ntpd-rs/observe.
  • Upgraded dependencies.
  • The command line interface for ntp-ctl and ntp-metrics-exporter has changed.
  • The copyright from the project changed from 'Internet Security Research Group and Contributors' to 'Tweede Golf and Contributors'
  • The /etc/ntpd-rs/ntp.toml file in the deb and rpm packages provided by us is now managed by their respective package managers. This may result in your config file being overwritten initially, but future upgrades should be handled gracefully.
  • Added actual ip address of ntp server to observable data. The address field has been renamed for this.

Fixed

  • Fix bug around handling of leap second indicators.
  • Fixed bug around handling of accumulated step thresholds.
  • Fixed incorrect reference id being used by server.
  • Fixed user creation in packages.
  • Fixed peer trying to request more cookies than it can encode in it's packet buffer.
  • Fixed server not sending nts naks when receiving nts packets it can't decrypt.
  • Fixed source poll interval not being updated in stats.

Removed

  • Removed support for the RFC5905 algorithm.
  • Sources and servers can no longer be configured via the command line.
  • Logging can now only be configured via a log level, no other filtering is possible.
  • The daemon control socket has been removed, the daemon can no longer be reconfigured at runtime.
