+2.65 [KK 2010-04-26]
+- Bugfix in backend/connect.cc - if the determination whether a back
+ end is available goes haywire, the client socket may stay open and
+ not be consumed. Thanks Franz J. for reporting!
+- Version stamped as STABLE.
+
+2.64 [KK 2010-01-29]
+- Fixed signal handling for start/stop/restart.
+- Web interface now immediately shuts down at a stop request, so that
+ next xr instances can grab the web interface port immediately.
+
+2.63 [KK 2010-01-11]
+- Previous 2.62 stamped as stable, 2.63 will be the new development
+ trunk.
+
+2.62 [KK 2010-01-08]
+- Fixed possible coredump cause in Balancer::serve(), which might
+ explain some troubles during high load (many really concurrent requests).
+
+2.61 [KK 2009-11-17]
+- Netbuffer::netwrite() will abort after 5 attempts that yield 0
+ written bytes. Probable cause of CPU hogging - thx Franz J. for
+ reporting.
+- Fixed potential cause of crashes in base class for Dispatcher
+ (algorithm handler would not get initialized in the constructors).
+
+2.60 [KK 2009-11-02]
+- Some errors demoted to informational messages to choke the amount of
+ log information that's generated.
+
+2.59 [KK 2009-10-14]
+- Bugfix in logger handling of xrctl, read
+ http://xrforum.org/viewtopic.php?t=495 if you fancy. Thanks Hobbit
+ for reporting this!
+
+2.58 [KK 2009-10-14]
+- Added test/ftp.xml as a sample ftp service configuration.
+- Implemented URL-based dispatching: flag --url-match/-j, present in
+ xrctl, tested in test/urlmatch.xml, added to web interface
+- Usage information now shows long versions of flags first.
+
+2.57 [KK 2009-09-14]
+- Output of "xrctl status" colorized when a service is not running,
+ thanks Frederik D. for the suggestion and the code!
+- Small cleanup of xrctl's usage information.
+
+2.56 [KK 2009-05-26]
+- Bugfix in cleaning of IPStore map
+- Implemented flag --remove-reservations (xrctl: tag: removereservations)
+- Timeouts adjusted: all read time outs set to 30, client-write set to
+ 5, backend-write set to 3
+- Implemented tag prefixtimestamp in system block to force timestamping.
+
+2.55 [KK 2009-05-13]
+- Implemented connection error counting of back ends.
+- Select-handling revised: atomic readability and writeability checks,
+ see xr/fdset/wait.cc and wait_r(), wait_w(), wait_rw().
+- Checks for connect() success can be configured to verify only
+ writeable status of a socket (see xr/backend/connect.cc, macro
+ CONNECTCHECK_ONLY_WRITABLE in xr/etc/Makefile.class).
+- Added test/xr-mysql-connect.
+- Added commands kill and killstart to xrctl. Action restart renamed
+ to stopstart.
+- Added simple benchmarking under test/: xr-http-test (based on an
+ older script) and xr-smtp-test. Plus a simple analyzer of the
+ reported timings, xr-analyze-test.
+- Revamped stored-ip dispatcher, added IPStore class to keep track of clients.
+
+2.54 [KK 2009-04-29]
+- Stamped new STABLE version.
+
+2.53 [KK 2009-04-24]
+- test/xr-client-ping now can live without LWP::UserAgent. When this
+ Perl module is not present, the script will fall back to wget/curl.
+- Upon thread kill, sockets are closed using socketclose()
+ (sys/socketclose.cc), which also shutdown()s the socket.
+- Bugfix in xrctl regarding new format of client/backend timeout.
+
+2.52 [KK 2009-04-21]
+- Bugfix in the roundrobin dispatcher. When only one back end would be
+ up, then the roundrobin dispatcher would incorrectly compute the
+ right back end. This bug only became visible with host-matching in
+ HTTP mode.
+
+2.51 [KK 2009-04-15]
+- Separate "write" timeouts introduced in flags -t and -T
+- Web interface activity overview includes client ip addresses
+- Added test/xr-client-ping (see docs)
+
+2.50 [KK 2009-03-30]
+- Bugfix in activation of the onfail script in the checkup thread.
+- Compilation flag -Werror only passed to the compiler when on the
+ development system Thera.local (see xr/etc/Makefile.class).
+- Onstart, onend and onfail scripts (when present) are invoked with a
+ third argument, the number of connections at the time
+- Set-Cookie header directive (see the HTTP dispatcher) attaches an
+ explicit path "/".
+- Rewired the tcp dispatcher and http dispatcher to use a common
+ buffer inside the tcp dispatcher (instead of 2 separate ones).
+
+2.49 [KK 2009-03-27]
+- Implemented onfail hook (to complement onstart/onend, flag -y).
+
+2.48 [KK 2009-03-26]
+- Implemented onstart/onend hooks (flags -z, -Z).
+- Sticky HTTP mode inspects the URI (parameter XRTarget) when no
+ sticky cookie is present.
+
+2.47 [KK 2009-03-04]
+- Stored-ip dispatching was enhanced to "anticipate" reconnects from
+ previously seen clients. The number of anticipated connections is taken
+ into account when dispatching a new client.
+- Bugfix in command line parsing of dispatch mode lax-stored-ip (would
+ be recognized as strict).
+
+2.46 [KK 2009-02-18]
+- Dispatcher-related classes moved under directory xr/Dispatchers/.
+- UDP balancer implementation started (code stubs in place).
+- xrctl bugfixed: a backend-scope maxconnections statement would
+ confuse the global server block. Thanks Rajeev for reporting.
+
+2.45 [KK 2009-02-18]
+- Usage information formatted.
+- Rubberstamped "stable"!
+
+2.44 [KK 2009-02-11]
+- Reviewed code for "throw"s (edited for consistency).
+- Bug in Webinterface::execute() (during accept()). Thanks Vladimir T.
+ for reporting and testing.
+
+2.43 [KK 2009-02-09]
+- Added Httpbuffer::replaceheader() methods
+- Added flag -I (to replace Host: headers), integrated in xrctl /
+ webinterface
+- Webinterface reports approx. # of open fd's and the limit (in activity)
+
+2.42 [KK 2009-01-28]
+- Bugfix in "xrctl generateconfig". The activity info introduced
+ before (which the web interface now emites), confused xrctl.
+- Bugfix in sys/ipmatch.cc: mask matching corrected for systems where
+ longs are not 4 bytes (64bit systems).
+- Bugfix in hashed-ip dispatch mode: When no back ends were available,
+ the dispatcher would crash (fixed).
+- XSLT stylesheet that transforms web interface slightly changed to
+ improve the looks.
+- Bugfix in xrctl's "rotate" action. Thanks "ncisrael" for reporting
+ it in the forum.
+
+2.41 [KK 2009-01-05]
+- Bugfix in xrctl, thanks Eddie for reporting it.
+
+2.40 [KK 2009-01-03]
+- Netbuffer::read() failures are no longer logged as errors, but as
+ verbose messages.
+- XML configuration now supports "logger" to redefine logger program.
+- Small changes to xrctl: ps command is auto-guessed when not
+ specified in the XML configuration.
+
+2.39 [KK 2008-12-04]
+- Added Httpbuffer::reset()
+- The HTTP dispatcher will show back end error returns (when the HTTP
+ code is in the 400 or 500 range)
+- main() will show runtime limits when invoked with -v
+- The HTTP dispatcher no longer downgrades to HTTP/1.0 and closed
+ connections. Webserver back ends can do this.
+- Exceptions during the sending of an error page in HTTP mode are
+ discarded, no longer logged.
+- Mutex lock added around thread startups (see Thread::start()), when
+ requested soq in sys/sys.
+- Mutex locks around malloc()/realloc(), when requested so in sys/sys.
+- Fixed possible socket leak in TcpDispatcher::execute(). The back end
+ socket might not have been closed when the dispatch phase crashed.
+- Dispatchers are now derived from a new base class Dispatcher, in
+ preparation for UDP handling.
+- Timestamp handling centralized in a class Timestamp.
+- Messaging (msg(), debugmsg(), reportmsg(), warnmsg()) centralized.
+- Started threads are administered in Threadlist. Separate threads are
+ killable from the web interface, or all threads to a given back end.
+
+2.38 [KK 2008-11-19]
+- Bugfix in xrctl: Weights and max connections in back ends are now
+ passed correctly.
+- Added version ID to xrctl.
+
+2.37 [KK 2008-11-17]
+- Main accept-loop in Balancer::serve() doesn't throw an exception
+ when a network connection can't be accepted. The reason is shown in
+ a warnmsg().
+
+2.36 [KK 2008-11-11]
+- Typo bugfix in xrctl, fixed.
+- xrctl will take the environment's PATH if no path is given in the
+ configuration.
+
+2.35 [KK 2008-11-11]
+- The wakeup and checkup thread are always started, even when no
+ wakeups or checkups are defined. Reason is that later these timers
+ can be set in the web interface, so we want the threads running.
+ When no checks/wakeups are applicable, the threads will recheck each
