New in version 1.21 =================== * Don't include Linux kernel header files any longer : allows chrony to compile on recent distros. * Stop trying to use RTC if continuous streams of error messages would occur (Linux with HPET). New in version 1.20 =================== * Many small tidy-ups and security improvements * Improve documentation (RTC support in post 2.0 kernels) * Remove trailing \n from syslog messages * Syslog messages now include IP and port number when packet cannot be sent. * Added the "acquisitionport" directive.

New pidfile directive in configuration file. * Any size subnet is now allowed in allow and deny commands. (Example: 6.7.8/20 or 6.7.8.x/20 (any x) mean a 20 bit subnet). * The environment variables CC and CFLAGS passed to configure can now be used to select the compiler and optimisation/debug options to use * Write syslog messages when chronyd loses synchronisation. * Print GPL text when chronyc is run. * Add NTP broadcast server capability (new broadcast directive). * Add 'auto_offline' option to server/peer (conf file) or add server/peer (via chronyc). * Add 'activity' command to chronyc, to report how many servers/peers are currently online/offline. * Fix long-standing bug with how the system time quantum was calculated. * Include support for systems with HZ!=100 (HZ is the timer interrupt frequency). * Include example chrony.conf and chrony.keys files (examples subdirectory). * Include support for readline in chronyc. New in version 1.16.1 ===================== * Fix compilation problem on Linux 2.4.13 (spinlock.h / spinlock_t) New in version 1.16 =================== * More informative captions for 'sources' and 'sourcestats' commands in chronyc (use 'sources -v' and 'sourcestats -v' to get them). * Correct behaviour for Solaris versions>=2.6 (dosynctodr not required on these versions.) * Remove some compiler warnings (Solaris) * If last line of keys file doesn't have end-of-line, don't truncate final character of that key. * Change timestamp format used in logfiles to make it fully numeric (to aid importing data into spreadsheets etc) * Minor documentation updates and improvements. New in version 1.15 =================== * Add contributed change to 'configure' to support Solaris 2.8 on x86 * Workaround for assertion failure that arises if two received packets occur close together. (Still need to find out why this happens at all.) * Hopefully fix problem where fast slewing was incompatible with machines that have a large background drift rate (=> tick value went out of range for adjtimex() on Linux.) * Fix rtc_linux.c compile problems with 2.4.x kernel include files. * Include support for RTC device not being at /dev/rtc (new rtcdevice directive in configuration file). * Include support for restricting network interfaces for commands (new bindcmdaddress directive in configuration file) * Fix potential linking fault in pktlength.c (use of CROAK macro replaced by normal assert). * Add some material on bug reporting + contributing to the chrony.texi file * Made the chrony.texi file "Vim6-friendly" (removed xrefs on @node lines, added folding markers to chapters + sections.) * Switched over to GPL for the licence New in version 1.14 =================== * Fix compilation for certain other Linux distributions (including Mandrake 7.1) New in version 1.13 =================== * Fixed compilation problems on Redhat/SuSE installations with recent 2.2.x kernels. * Minor tidy-ups and documentation enhancements. * Add support for Linux 2.4 kernels New in version 1.12 =================== * Trial fix for long-standing bug in Linux RTC estimator when system time is slewed. * Fix bug in chronyc if -h is specified without a hostname * Fixes to logging various error conditions when operating in daemon mode. * More stuff under contrib/ * Changes to README file (e.g. about the new chrony-users mailing list) New in version 1.11a ==================== * Minor changes to contact details * Minor changes to installation details (chrony subdirectory under doc/) New in version 1.11 =================== * Improve robustness of installation procedure * Tidy up documenation and contact details * Distribute manual as .txt rather than as .ps * Add -n option to chronyc to work with numeric IP addresses rather than names. * Add material in contrib subdirectory * Improve robustness of handling drift file and RTC coefficients file * Improve robustness of regression algorithm New in version 1.1 ================== Bug fixes --------- * Made linear regression more resistant to rounding errors (old one occasionally generated negative variances which made everything go haywire). Trap infinite or 'not-a-number' values being used to alter system clock to increase robustness further. Other changes/Enhancements -------------------------- * Support for Linux 2.1 and 2.2 kernels * New command 'makestep' in chronyc to immediately jump the system time to match the NTP estimated time (Linux only) - a response to systems booting an hour wrong after summertime/wintertime changes, due to RTCs running on local time. Needs extending to Sun driver files too. * New directives 'logchange' and 'mailonchange' to log to syslog or email to a specific address respectively if chronyd detects a clock offset exceeding a defined threshold. * Added capability to log all client/peer NTP accesses and command accesses (can be turned off with conf file directive 'noclientlog'). Added 'clients' command to chronyc to display this data. * Improved manual mode to use robust regression rather than 2 point fit. * Added 'manual list' and 'manual delete' commands to chronyc to allow display of entered timestamps and discretionary deletion of outliers. * If host goes unsynchronised the dummy IP address 0.0.0.0 is detected to avoid attempting a reverse name lookup (to stop dial on demand IP links from being started) * Changed chronyc/chronyd protocol so messages are now all variable length. Saves on network bandwidth particularly for large replies from chronyd to chronyc (to support the clients command). * Added bindaddress directive to configuration file, to give additional control over limiting which hosts can access the local server. * Groundwork done for a port to Windows NT to compile with Cygwin toolkit. chronyc works (to monitor another host). sys_winnt.c needs finishing to use NT clock control API. Program structure needs adapting to use Windows NT service functions, so it can be started at boot time. Hopefully a Windows NT / Cygwin guru with some spare time can take this port over :-) New in version 1.02 =================== Bug fixes --------- * Fix error messages in chronyc if daemon is not reachable. * Fix config file problem for 'allow all' and 'deny all' without a trailing machine address. * Remove fatal failed assertion if command socket cannot be read from in daemon. * Rewrote timezone handling for Linux real time clock, following various reported problems related to daylight saving. Other changes/Enhancements -------------------------- * Configure script recognizes BSD/386 and uses SunOS 4.1 driver for it. * Log files now print date as day-month-year rather than as a day number. Milliseconds removed from timestamps of logged data. Banners included in file to give meanings of columns. * Only do 1 initial step (followed by a trimming slew) when initialising from RTC on Linux (previously did 2 steps). New in version 1.01 =================== Bug fixes --------- * Handle timezone of RTC correctly with respect to daylight saving time * Syntax check the chronyc 'local' command properly * Fixed assertion failed fault in median finder (used by RTC regression fitting) Other changes/Enhancements -------------------------- * Log selection of new NTP reference source to syslog. * Don't zero-pad IP address fields * Add new command to chronyc to allow logfiles to be cycled. * Extend allow/deny directive syntax in configuration file to so directive can apply to all hosts on the Internet. * Tidy up printout of timestamps to make it clear they are in UTC * Make 'configure' check the processor type as well as the operating system.
