38 * A lot of minor cleanups and fixes
40 This release is backwards compatible with Avahi 0.6.x with x < 17.
45 This is a bugfix release, it fixes one DoS (100% CPU Usage) and a regression
48 * Revert previous patch to check nlmsg_pid as it is bogus and breaks in
49 many cases, notably when using NetworkManager (Closes: #72)
50 * Replace with new SO_PASSCRED-based check of the sending UID, which
51 seems to work better (Closes: #72)
52 * Handle some errors in libdns_sd more gracefully the way the real
53 libdns_sd does (Closes: #64)
54 * Apply fix for Linux 2.6.19+ where IFA_RTA / IFLA_RTA is no longer
56 * Fix doxygen comments for avahi watch, thanks to tedp (Closes: #77)
57 * Make d-bus version detection work for >= 1.0 (Closes: #71)

75 * Fix dbus_service_browser not setting AVAHI_LOOKUP_RESULT_OUR_OWN.
77 This release is backwards compatible with Avahi 0.6.x with x < 15.
82 This release fixes some bugs and includes a new component.
86 * Add new daemon "avahi-autoipd" which is an implementation of
87 IPv4LL as defined in RFC3927, a technology for assigning link-local IP
88 addresses without DHCP server. The same functionality has been available on
89 Windows under the name APIPA. While it is not the first implemenatation of
90 this technology for Free operating systems it is clearly the most powerful
91 and hopefully even the most secure. (Because it chroot()s and drops
92 priviliges and suchlike) For more information, especially about packaging
93 this new tool for distributions, please make sure to read:
94 http://avahi.org/wiki/AvahiAutoipd
95 and of course the man page included in the tarball. For the rationale for
96 adding this program to the Avahi toolset please read this mailing list
98 http://lists.freedesktop.org/archives/avahi/2006-September/000863.html
99 * Fix a segfault in the code handling static host name registrations

107 * Other minor code cleanups
109 This release is backwards compatible with Avahi 0.6.x with x < 14.
111 Please note that this version doesn't compile on NetBSD, patches
114 Please note that avahi-autoipd is available on Linux only for
115 now. Patches welcome. It is recommended to pass --disable-autoipd to
116 "configure" on non-Linux operating systems, otherwise the build will
122 This release fixes some bugs and includes minor enhancements.
125 * Add a new D-Bus method for changing the mDNS host name during
126 runtime. This functionality is only available to members of the
127 UNIX group "netdev", which is the same access group that is
128 enforced by GNOME's NetworkManager daemon. Since NM will probably
129 be the most prominent user of this new method, we decided to limit
130 access to the same group. The access group can be set by passing
131 --with-avahi-priv-access-group= to "configure". If you need more
132 sophisticated access control you can freely edit
133 /etc/dbus/system.d/avahi-dbus.conf.
134 * Add a new utility "avahi-set-host-name" which is a command line
135 wrapper around the aforementioned SetHostName() method.
136 * Bonjour API compatibility library:
137 * Implement DNSServiceUpdateRecord()
138 * Allow passing NULL as callback function for
140 * Implement subtype registration in DNSServiceRegister() in a
141 way that is compatible with Bonjour.
142 * Update to newer copy of dns_sd.h
143 * If the host name changes update names of static services wich
145 * Don't build documentation about embedding the Avahi mDNS stack into
146 other programs by default. This is a feature used only by embedded
147 developers. Pass --enable-core-docs to "configure" to enable
148 building these docs, like in Avahi <= 0.6.12.
149 * Build Qt documentation only when Qt support is enabled in
150 the configuration. Same for GLib.
151 * Change algorithm used to find a new host name on conflict. In
152 Avahi <= 0.6.12 a conflicting host name of "foobar" would be
153 changed to the new name "foobar2". With 0.6.13 "foobar-2" will be
154 picked instead. This follows Bonjour's behaviour and has the
155 advantage not confusing people with regular host names ending in
157 * Don't disable all static services when SIGHUP is recieved.
158 * Fix build when Avahi is configured without Gtk+ but with Python
160 * Fix build on MacOS X
161 * Support using Solaris DBM instead of gdbm for the service type
162 database. The latter is still recommended
163 * Minor other fixes and documentation updates
165 This release is backwards compatible with Avahi 0.6.x with x < 13.
170 This is a bugfix and general cleanups release.
173 * Compatibility with newer D-Bus releases (0.9x)
174 * Compatibility with DBUS builds with --disable-checks
175 * Fix an error in the DBUS event loop wrapping which
176 caused the avahi client libraries to dispatch some events
177 too late when used with D-BUS 0.62 and newer.
178 * avahi-daemon: fix a minor memory leak in the DBUS code.
179 * avahi-glib: some GLIB adapter cleanups
180 * avahi-dnsconfd: fix segfault when passing an invalid command
182 * avahi-test: portability patches for Solaris
183 * avahi-browse: flush STDOUT after each line, making it useful
185 * update service type database
187 This release is backwards compatible with Avahi 0.6.x with x < 12.
192 This is a bugfix and portability release.
196 * avahi-sharp: fix a fatal error in object disposal code
197 * add a few new entries to the servivce type database
198 * fix potential crash when the daemon shuts down
199 * compatibility with newer autoconf versions
201 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
202 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
207 This is mostly a bugfix release. Two of the bugs fixed are security
208 sensitive: a remote denial-of-service vulnerability and a buffer
209 overflow that can allow local users to become the 'avahi' user. We do
210 not consider either of them major security threats.
212 The DoS vulnerability can be exploited from a local network only. It
213 is not worth much, though, since mDNS can easily be flooded with
214 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
215 provoking a name conflict in perfect accordance with the specs.
217 The buffer overflow is hard to exploit remotely, only local users can
218 become the 'avahi' user. In addition the user is trapped inside a
219 chroot() environment (at least on Linux).
221 Anyhow, our security assessments are possibly as buggy as our
224 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
227 * Fix a buffer overflow in avahi-core
228 * Refuse to process invalid UTF8 data
229 * Automatically reconnect to the DBUS if we're kicked. (Works only if
230 chroot() is disabled)
231 * Don't hit an assert() in the client libs when the Avahi daemon is
233 * Enumerate all service types in the database in the Service
234 Discovery Applet for Gnome
235 * Improve the Bonjour compatibility layer to make it survive
236 GnomeMeeting's broken usage
237 * Deal properly with local non-ASCII hostnames
238 * AMD64 and FreeBSD portability fixes
239 * Filter double DNS server entries in avahi-dnsconfd
240 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
241 * Ported to Solaris (incomplete)
242 * Add _airport._tcp to our service type database
244 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
245 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

263 This release fixes some bugs and adds a few new features. Users of 0.6.7,
266 * Fix broken parsing of static hosts file
267 * Improve out-of-the-box Debian support
268 * Add configuration option to allow mDNS over POINTOPOINT links.
269 This is a potential security hole and YMMV. See man page for details.
270 * Create $(localstatedir)/run on installation
272 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
273 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7.
278 This release fixes some bugs and adds a few new features

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

308 0.6.3, 0.6.4 and 0.6.5.
313 This release fixes some bugs and adds a new API function.
315 * avahi-browse: properly show services that are removed from the
317 * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and
319 * add new API function avahi_nss_support() and DBUS function
320 IsNSSSupportAvailable() which may be used to detect whether
321 libc's gethostbyname() supports mDNS domain names.
322 * patch avahi-bookmarks to make use of
323 IsNSSSupportAvailable(). avahi-bookmarks will now generate links
324 with real hostnames instead of numeric IP addresses if mDNS support
325 is detected for gethostbyname().
326 * add init script for Mandriva Linux
327 * speed up avahi_client_free()
329 * install missing header thread-watch.h
330 * fix avahi-bookmarks to work with certain twisted versions
331 * fix record updating

346 * avahi-sharp: correct some flags definitions
348 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2 and
351 A quick introduction how to use the new AvahiThreadedPool interface is
352 available in our Wiki:
354 http://avahi.org/wiki/RunningAvahiClientAsThread
359 This is a bugfix release. Everyone should update ASAP!
361 * avahi-sharp: make sure to append a trailing NUL byte to all C strings
362 * avahi-core: fix a double free() which occurs when wide area lookups timeout
364 This release is fully compatible with Avahi 0.6, 0.6.1 and 0.6.2.
369 This is mostly a bugfix release.
371 * Compatibility with DBUS 0.60 (Full compatibility with DBUS 0.3x and
373 * Fix introspection for some auxiliary DBUS objects
374 * Miscellaneous documentation updates
375 * Improve Autoconf support for detecting PTHREADS library
376 * Fix avahi-publish --help
377 * Workaround a DBUS limitation which might cause Avahi to die when a
378 user sends an empty TXT entry over DBUS
379 * Increase number of resolver/browser objects a DBUS client may create
380 * Remove fprintf() call in avahi_client_new()
383 This release is both up and downwards compatible with Avahi 0.6 and 0.6.1.
385 Avahi now has its own Domain (http://avahi.org) and a new Website!
387 And, most importantly, we now have a Logo:
388 http://avahi.org/chrome/site/avahi-trac.png
393 This is mostly a bugfix release.
395 * Fix a segfault when shutting down the daemon. Please note that this
396 issue was not security sensitive in any way but had the ugly side
397 effect that the daemon's PID file was not removed properly.
398 * Added init scripts for ArchLinux and FreeBSD
399 * Add DBUS API versioning through the new method GetAPIVersion()
400 * Build the HOWL compatibility library as "libhowl.so", instead of
401 "libavahi-compat-howl.so". This will help distributors to ensure
402 full API/ABI compatibility with HOWL out-of-the-box.
403 * Same for the Bonjour compatibility library
406 We encourage Linux users to update to libdaemon 0.10 since logging
407 does not work from a chroot() environment with older versions.
409 This release is fully API and ABI compatible with Avahi 0.6. This is
410 true for both the C libraries and the DBUS interface.
412 Packagers should read the new documentation file doc/COMPAT-LAYERS
413 which contains some information about maintaining full build system
414 compatibility in addition to ABI/API compatibility.

487 - Add option to generate links with hostnames instead of IPs
489 Avahi 0.2, the 'Dzień Dobry' release
490 ====================================
492 * Unfortunately this release broke the API/ABI of libavahi-client
493 with the following function removals
495 Removal of these functions may affect users of the 0.1 API
496 - avahi_service_resolver_block()
498 The following functions were simply for debugging information
499 and their removal should not affect anyone
500 - avahi_entry_group_get_dbus_path()

510 unless it is the only IP address on the interface.
511 * avahi-daemon will no longer fail to start if D-BUS is not
512 available (if configured with enable-dbus=warn)

537 * Fixed compilation and runtime issues on 64-bit distributions
541 Avahi 0.1, the "Guten Tag" release
542 ==================================
544 The Avahi team would like to announce the immediate availability of
545 Avahi 0.1 "Guten Tag".
547 Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
548 It allows programs to publish and discover services and hosts
549 running on a local network with no specific configuration. For
550 example you can plug into a network and instantly find printers to
551 print to, files to look at and people to talk to.
553 Avahi is designed to be compatible with the mDNS/DNS-SD specification
554 and boasts the following features
556 * Fully open source and freely available under the LGPL
557 * Full IPv4 and IPv6 support
558 * An embeddable mDNS stack
559 * Dynamic adjustment to network reconfiguration
560 * Daemon with DBUS API for desktop applications
561 * C library to interface with the DBUS API
562 * Compatible with other mDNS/DNS-SD implementations such as
563 Howl and Apple Bonjour (previously Rendezvous)
564 * Ability to correctly "reflect" mDNS between two or more LAN segments
565 * Ability to configure DNS servers based on mDNS/DNS-SD published
566 information, a feature that is very usefull on IPv6
567 which has no other mechanism for this.
568 * Combined with nss-mdns, allows hostname lookup such as
569 'laptop.local' without the configuration of a DNS server.
570 http://0pointer.de/lennart/projects/nss-mdns/
571 * Easy integration into GLIB, GTK other mainloop applications.
572 * Documentation and examples of both developer APIs and utilities.
574 mDNS/DNS-SD is part of a larger set of specifications for easy
575 configuration of networking known as "ZeroConf"
576 (http://www.zeroconf.org/), with the aim of allowing you to plug into
577 a network and instantly be able to interact with it's services.
579 Avahi was designed to be a fully free implementation, and is
580 available under the LGPL. Many other implementations of the mDNS/DNS-SD
581 specification were previously non-free, restricting their use in many
582 platforms such as the GNOME desktop and many distributions.
584 While Avahi is a 0.1 release, we feel it is feature complete and
585 available for immediate use, developers can make use of the Avahi
586 client library to provide above mentioned functionality in their
589 We unfortunately do not have a logo yet! We would love if someone
