The original announcement for the 4.2.6p5 version from December 2011:
Redwood City, CA - 2011/12/24 - The NTP Public Services Project (http://support.ntp.org/) is pleased to announce that NTP 4.2.6p5, a Point Release of the NTP Reference Implementation from the NTP Project, is now available at http://www.ntp.org/downloads.html and http://support.ntp.org/download. File-size: 4202539 bytes MD5 sum: 00df80a84ec9528fcfb09498075525bc ntp-4.2.6p5.tar.gz Focus: Bug fixes Severity: Medium This is a recommended upgrade. This release updates sys_rootdisp and sys_jitter calculations to match the RFC specification, fixes a potential IPv6 address matching error for the "nic" and "interface" configuration directives, supresses the creation of extraneous ephemeral associations for certain broadcastclient and multicastclient configurations, cleans up some ntpq display issues, and includes improvements to orphan mode, minor bug fixes and code clean-ups. New features / changes in this release: ntpd * Updated "nic" and "interface" IPv6 address handling to prevent mismatches with localhost [::1] and wildcard [::] which resulted from using the address/prefix format (e.g. fe80::/64) * Fix orphan mode stratum incorrectly counting to infinity * Orphan parent selection metric updated to includes missing ntohl() * Nonprintable stratum 16 refid no longer sent to ntp * Duplicate ephemeral associations suppressed for brodcastclient and multicastclient without broadcastdelay * Exclude undetermined sys_refid from use in loopback TEST12 * Exclude MODE_SERVER responses from KoD rate limiting * Include root delay in clock_update() sys_rootdisp calculations * get_systime() updated to exclude sys_residual offset (which only affected bits "below" sys_tick, the precision threshold) * sys.peer jitter weighting corrected in sys_jitter calculation ntpq * -n option extended to include the billboard "server" column * IPv6 addresses in the local column truncated to prevent overruns Please report any bugs, issues, or desired enhancements at http://bugs.ntp.org/. The NTP (Network Time Protocol) Public Services Project, which is hosted by Internet Systems Consortium, Inc. (http://www.isc.org/), provides support and additional development resources for the Reference Implementation of NTP produced by the NTP Project (http://www.ntp.org/).Please be aware that the download links, MD5 checksums and file sizes are not referring to the Meinberg installer which comes as an executable installer including the digitally signed binaries and required DLLs.
