159 This release is backwards compatible with Avahi 0.6.x with x < 20.
164 This is a bugfix release, but also adds a new component "avahi-ui-sharp".
166 * Rename zssh/zvnc to bssh/bvnc to avoid a name collision with another
167 free software tool, on request of the Debian developers. I hope
168 this name change early in the life of bssh/bvnc won't be too
169 difficult to handle by the distributors.
170 * Add man page for bssh/bvnc
171 * avahi-ui: fix segfault when browsing in empty domains

176 range in avahi-autoipd, as required by RC3927 section 2.1
177 * No longer publish the Avahi service identification cookie anymore

263 This release is backwards compatible with Avahi 0.6.x with x < 15.
268 This release fixes some bugs and includes a new component.
272 * Add new daemon "avahi-autoipd" which is an implementation of
273 IPv4LL as defined in RFC3927, a technology for assigning link-local IP
274 addresses without DHCP server. The same functionality has been available on
275 Windows under the name APIPA. While it is not the first implemenatation of
276 this technology for Free operating systems it is clearly the most powerful
277 and hopefully even the most secure. (Because it chroot()s and drops
278 privileges and suchlike) For more information, especially about packaging
279 this new tool for distributions, please make sure to read:
280 http://avahi.org/wiki/AvahiAutoipd
281 and of course the man page included in the tarball. For the rationale for
282 adding this program to the Avahi toolset please read this mailing list
284 http://lists.freedesktop.org/archives/avahi/2006-September/000863.html

297 Please note that this version doesn't compile on NetBSD, patches
300 Please note that avahi-autoipd is available on Linux only for
301 now. Patches welcome. It is recommended to pass --disable-autoipd to
302 "configure" on non-Linux operating systems, otherwise the build will
308 This release fixes some bugs and includes minor enhancements.
311 * Add a new D-Bus method for changing the mDNS host name during
312 runtime. This functionality is only available to members of the
313 UNIX group "netdev", which is the same access group that is
314 enforced by GNOME's NetworkManager daemon. Since NM will probably
315 be the most prominent user of this new method, we decided to limit
316 access to the same group. The access group can be set by passing
317 --with-avahi-priv-access-group= to "configure". If you need more
318 sophisticated access control you can freely edit
319 /etc/dbus/system.d/avahi-dbus.conf.
320 * Add a new utility "avahi-set-host-name" which is a command line
321 wrapper around the aforementioned SetHostName() method.
322 * Bonjour API compatibility library:
323 * Implement DNSServiceUpdateRecord()
324 * Allow passing NULL as callback function for
326 * Implement subtype registration in DNSServiceRegister() in a
327 way that is compatible with Bonjour.
328 * Update to newer copy of dns_sd.h
329 * If the host name changes update names of static services wich
331 * Don't build documentation about embedding the Avahi mDNS stack into
332 other programs by default. This is a feature used only by embedded
333 developers. Pass --enable-core-docs to "configure" to enable
334 building these docs, like in Avahi <= 0.6.12.
335 * Build Qt documentation only when Qt support is enabled in
336 the configuration. Same for GLib.
337 * Change algorithm used to find a new host name on conflict. In
338 Avahi <= 0.6.12 a conflicting host name of "foobar" would be
339 changed to the new name "foobar2". With 0.6.13 "foobar-2" will be
340 picked instead. This follows Bonjour's behaviour and has the
341 advantage not confusing people with regular host names ending in
343 * Don't disable all static services when SIGHUP is received.
344 * Fix build when Avahi is configured without Gtk+ but with Python
346 * Fix build on MacOS X
347 * Support using Solaris DBM instead of gdbm for the service type
348 database. The latter is still recommended
349 * Minor other fixes and documentation updates
351 This release is backwards compatible with Avahi 0.6.x with x < 13.
356 This is a bugfix and general cleanups release.
359 * Compatibility with newer D-Bus releases (0.9x)
360 * Compatibility with DBUS builds with --disable-checks
361 * Fix an error in the DBUS event loop wrapping which
362 caused the avahi client libraries to dispatch some events
363 too late when used with D-BUS 0.62 and newer.
364 * avahi-daemon: fix a minor memory leak in the DBUS code.
365 * avahi-glib: some GLIB adapter cleanups
366 * avahi-dnsconfd: fix segfault when passing an invalid command
368 * avahi-test: portability patches for Solaris
369 * avahi-browse: flush STDOUT after each line, making it useful
371 * update service type database
373 This release is backwards compatible with Avahi 0.6.x with x < 12.
378 This is a bugfix and portability release.
382 * avahi-sharp: fix a fatal error in object disposal code
383 * add a few new entries to the servivce type database
384 * fix potential crash when the daemon shuts down
385 * compatibility with newer autoconf versions
387 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
388 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
393 This is mostly a bugfix release. Two of the bugs fixed are security
394 sensitive: a remote denial-of-service vulnerability and a buffer
395 overflow that can allow local users to become the 'avahi' user. We do
396 not consider either of them major security threats.
398 The DoS vulnerability can be exploited from a local network only. It
399 is not worth much, though, since mDNS can easily be flooded with
400 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
401 provoking a name conflict in perfect accordance with the specs.
403 The buffer overflow is hard to exploit remotely, only local users can
404 become the 'avahi' user. In addition the user is trapped inside a
405 chroot() environment (at least on Linux).
407 Anyhow, our security assessments are possibly as buggy as our
410 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
413 * Fix a buffer overflow in avahi-core
414 * Refuse to process invalid UTF8 data
415 * Automatically reconnect to the DBUS if we're kicked. (Works only if
416 chroot() is disabled)
417 * Don't hit an assert() in the client libs when the Avahi daemon is
419 * Enumerate all service types in the database in the Service
420 Discovery Applet for Gnome

424 * AMD64 and FreeBSD portability fixes
425 * Filter double DNS server entries in avahi-dnsconfd
426 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
427 * Ported to Solaris (incomplete)
428 * Add _airport._tcp to our service type database
430 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
431 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

449 This release fixes some bugs and adds a few new features. Users of 0.6.7,
452 * Fix broken parsing of static hosts file
453 * Improve out-of-the-box Debian support
454 * Add configuration option to allow mDNS over POINTOPOINT links.
455 This is a potential security hole and YMMV. See man page for details.
456 * Create $(localstatedir)/run on installation
458 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
459 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7.

467 * Work around kernel bugs regarding multicast group membership
468 * ia64 portability fixes
469 * Don't require X11 to run avahi-bookmarks
470 * API: Return AVAHI_ERR_IS_EMPTY when the user tries to commit an
472 * Improved Slackware and Fedora suppport
474 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,

494 0.6.3, 0.6.4 and 0.6.5.
499 This release fixes some bugs and adds a new API function.
501 * avahi-browse: properly show services that are removed from the
503 * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and
505 * add new API function avahi_nss_support() and DBUS function
506 IsNSSSupportAvailable() which may be used to detect whether
507 libc's gethostbyname() supports mDNS domain names.
508 * patch avahi-bookmarks to make use of
509 IsNSSSupportAvailable(). avahi-bookmarks will now generate links
510 with real hostnames instead of numeric IP addresses if mDNS support
511 is detected for gethostbyname().
512 * add init script for Mandriva Linux
513 * speed up avahi_client_free()
515 * install missing header thread-watch.h
516 * fix avahi-bookmarks to work with certain twisted versions
517 * fix record updating

537 A quick introduction how to use the new AvahiThreadedPool interface is
538 available in our Wiki:
540 http://avahi.org/wiki/RunningAvahiClientAsThread
545 This is a bugfix release. Everyone should update ASAP!
547 * avahi-sharp: make sure to append a trailing NUL byte to all C strings
548 * avahi-core: fix a double free() which occurs when wide area lookups timeout
550 This release is fully compatible with Avahi 0.6, 0.6.1 and 0.6.2.

559 * Fix introspection for some auxiliary DBUS objects
560 * Miscellaneous documentation updates
561 * Improve Autoconf support for detecting PTHREADS library

564 user sends an empty TXT entry over DBUS
565 * Increase number of resolver/browser objects a DBUS client may create
566 * Remove fprintf() call in avahi_client_new()
569 This release is both up and downwards compatible with Avahi 0.6 and 0.6.1.
571 Avahi now has its own Domain (http://avahi.org) and a new Website!
573 And, most importantly, we now have a Logo:
574 http://avahi.org/chrome/site/avahi-trac.png
579 This is mostly a bugfix release.
581 * Fix a segfault when shutting down the daemon. Please note that this
582 issue was not security sensitive in any way but had the ugly side
583 effect that the daemon's PID file was not removed properly.
584 * Added init scripts for ArchLinux and FreeBSD
585 * Add DBUS API versioning through the new method GetAPIVersion()
586 * Build the HOWL compatibility library as "libhowl.so", instead of
587 "libavahi-compat-howl.so". This will help distributors to ensure
588 full API/ABI compatibility with HOWL out-of-the-box.
589 * Same for the Bonjour compatibility library
592 We encourage Linux users to update to libdaemon 0.10 since logging
593 does not work from a chroot() environment with older versions.
595 This release is fully API and ABI compatible with Avahi 0.6. This is
596 true for both the C libraries and the DBUS interface.
598 Packagers should read the new documentation file doc/COMPAT-LAYERS
599 which contains some information about maintaining full build system
600 compatibility in addition to ABI/API compatibility.

639 * New Mono bindings, allowing you to use Avahi from
640 any CLI language such as C#
641 * Attempt auto-detection of the D-BUS system bus address
642 * Include a 'cookie' in all published records which allows us
643 to reliably determine if a service is the same as another.
644 * Add API to determine if services are local
645 * Better support for threading with AvahiSimplePoll
646 * Add some new StringList functions to help binding to it in
648 * Various build and run-time bug fixes
650 Avahi 0.4, the 'Hyvää päivää' release
651 =====================================
653 * Renamed the include dirs for the Qt bindings to include the
654 version number, as they may diverge in future.
655 * Fix a critical bug in avahi-daemon triggered by configuring an interface
656 with various DHCP clients when you have no other active addresses which
657 caused avahi-daemon to abort.
658 * Move to using python-gdbm exclusivly for the service type database.

675 Avahi 0.2, the 'Dzień Dobry' release
676 ====================================
678 * Unfortunately this release broke the API/ABI of libavahi-client
679 with the following function removals
681 Removal of these functions may affect users of the 0.1 API
682 - avahi_service_resolver_block()
684 The following functions were simply for debugging information
685 and their removal should not affect anyone
686 - avahi_entry_group_get_dbus_path()
687 - avahi_domain_browser_get_dbus_path()
688 - avahi_service_type_browser_get_dbus_path()
689 - avahi_service_browser_get_dbus_path()
691 Note that while the libavahi-client API changed slightly, the DBUS
692 API itself has only had additions and no existing definitions
695 * avahi-daemon will now ignore local IP addresses with the "link" scope
696 unless it is the only IP address on the interface.
697 * avahi-daemon will no longer fail to start if D-BUS is not
698 available (if configured with enable-dbus=warn)

706 * Fixed a typo in avahi-glib.pc that stopped programs using
707 the GLIB api from compiling correctly
708 * A critical bug in the reflector was fixed where it may go into a
709 state of constantly flooding queries out to the network.

723 * Fixed compilation and runtime issues on 64-bit distributions
727 Avahi 0.1, the "Guten Tag" release
728 ==================================
730 The Avahi team would like to announce the immediate availability of
731 Avahi 0.1 "Guten Tag".
733 Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
734 It allows programs to publish and discover services and hosts
735 running on a local network with no specific configuration. For
736 example you can plug into a network and instantly find printers to
737 print to, files to look at and people to talk to.
739 Avahi is designed to be compatible with the mDNS/DNS-SD specification
740 and boasts the following features
742 * Fully open source and freely available under the LGPL
743 * Full IPv4 and IPv6 support
744 * An embeddable mDNS stack
745 * Dynamic adjustment to network reconfiguration
746 * Daemon with DBUS API for desktop applications
747 * C library to interface with the DBUS API
748 * Compatible with other mDNS/DNS-SD implementations such as
749 Howl and Apple Bonjour (previously Rendezvous)
750 * Ability to correctly "reflect" mDNS between two or more LAN segments
751 * Ability to configure DNS servers based on mDNS/DNS-SD published
752 information, a feature that is very usefull on IPv6
753 which has no other mechanism for this.
754 * Combined with nss-mdns, allows hostname lookup such as
755 'laptop.local' without the configuration of a DNS server.
756 http://0pointer.de/lennart/projects/nss-mdns/
757 * Easy integration into GLIB, GTK other mainloop applications.
758 * Documentation and examples of both developer APIs and utilities.
760 mDNS/DNS-SD is part of a larger set of specifications for easy
761 configuration of networking known as "ZeroConf"
762 (http://www.zeroconf.org/), with the aim of allowing you to plug into
763 a network and instantly be able to interact with its services.
765 Avahi was designed to be a fully free implementation, and is
766 available under the LGPL. Many other implementations of the mDNS/DNS-SD
767 specification were previously non-free, restricting their use in many
768 platforms such as the GNOME desktop and many distributions.
770 While Avahi is a 0.1 release, we feel it is feature complete and
771 available for immediate use, developers can make use of the Avahi
772 client library to provide above mentioned functionality in their
775 We unfortunately do not have a logo yet! We would love if someone
