This is a verbatim copy of the files at that stage of the repository that was
built from the CVS import.  It allows future development to see a bit of recent
history, but without carrying around the baggage going back to 1997.  If that
is really required, git grafts can be used.

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. (Kalle Olavi Niemitalo)
* Use uname(2) instead of /proc/version to get kernel version.
* Merge support for Linux on Alpha
* Merge support for 64bit architectures
* Don't link -lm if it's not needed
* Fix Solaris build (broken by 64bit change)
* Fix for Linux on SH-5 (floating point denorm handling).
* Add detection of Linux 2.5
* Allow arbitrary value of HZ in Linux kernel
New in version 1.19
===================
* Auto-detect kernel's timer interrupt rate (so-called 'HZ') when chronyd
starts instead of relying on compiled-in value.
* Fix 2 bugs in function that creates the directory for the log and dump files.
* Amended webpage URL and contact details.
* Generate more informative syslog messages before exiting on failed
assertions.
* Fix bugs in clamping code for the tick value used when slewing a large
offset.
* Don't chown files to root during install (should be pointless, and makes RPM
building awkward as ordinary user.)
* Include chrony.spec file for building RPMs
New in version 1.18
===================
* Amend homepage and mailing list information to chrony.sunsite.dk
* Delete pidfile on exit from chronyd.
* Improvements to readline interface to chronyc
* Only generate syslog message when synchronisation is initially lost (instead
of on every failed synchronisation attempt)
* Use double fork approach when initialising daemon.
* More things in contrib directory.
* New options to help package builders: --infodir/--mandir for configure, and
DESTDIR=xxx for make. (See section 2.2 of chrony.txt for details).
* Changed the wording of the messages generated by mailonchange and logchange
directives.
New in version 1.17
===================
* Port to NetBSD
* Configuration supports Linux on PPC
* Fix compilation warnings
* Several documentation improvements
* Bundled manpages (taken from the 'missing manpages project')
* Cope with lack of bzero function for Solaris 2.3 systems
* Store chronyd's pid in a file (default /var/run/chronyd.pid) and check if
chronyd may already be running when starting up. 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).

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.
