4 This is a bugfix release, but also adds a new component "avahi-ui-sharp".
6 * Rename zssh/zvnc to bssh/bvnc to avoid a name collision with another
7 free software tool, on request of the Debian developers. I hope
8 this name change early in the life of bssh/bvnc won't be too
9 difficult to handle by the distributors.
10 * avahi-ui: fix segfault when browsing in empty domains
11 * avahi-ui: allow GTK_RESPONSE_OK, _YES and _APPLY besides _ACCEPT as
12 positive dialog response codes

14 * Don't pick the first and the last 256 IP addresses from the IPV4LL
15 range in avahi-autoipd, as required by RC3927 section 2.1
16 * No longer publish the Avahi service identification cookie anymore
17 by default. It was a bad idea in the first place. A better
18 replacement will hopefully be made available in Avahi eventually.
19 * Properly set umask before writing to /var/lib/avahi-autoipd
20 * Update .deskop files to work around KDE menu issue
21 * Various build fixes and other minor fixes and updates

28 This is a bugfix release, adds a few new features and includes a new
31 * Add a new library libavahi-ui which contains a standard Gtk dialog
32 for browsing for services, and a new tool "zssh" that makes use of
33 it, which allows browsing for SSH and VNC servers and starts ssh or
34 xvncviewer if one item is selected.
35 * avahi-autoipd has been ported to FreeBSD (original patch from Bruce M Simpson)
36 * Improve OpenBSD, Solaris, MacOS X compatibility
37 * Linux inotify support for monitoring /etc/avahi/services/ and
38 /etc/avahi/hosts for changes. (Original patch from "behanw")

40 with the new option "-b".
41 * Enable GCC stack smashing protection if available and working (Patch from tedp)
42 * Improve compatibility with Bonjour's libdns_sd (patch from Chris Rivera)
43 * Various updates to the service type database (based on patches from uws)
44 * Fix a local DoS vulnerability (very low priority, all you can do is

63 * A lot of minor cleanups and fixes
65 This release is backwards compatible with Avahi 0.6.x with x < 17.
70 This is a bugfix release, it fixes one DoS (100% CPU Usage) and a regression
73 * Revert previous patch to check nlmsg_pid as it is bogus and breaks in
74 many cases, notably when using NetworkManager (Closes: #72)
75 * Replace with new SO_PASSCRED-based check of the sending UID, which
76 seems to work better (Closes: #72)
77 * Handle some errors in libdns_sd more gracefully the way the real
78 libdns_sd does (Closes: #64)
79 * Apply fix for Linux 2.6.19+ where IFA_RTA / IFLA_RTA is no longer
81 * Fix doxygen comments for avahi watch, thanks to tedp (Closes: #77)
82 * Make d-bus version detection work for >= 1.0 (Closes: #71)
83 * Dont dbus_connection_close on shared dbus connections (Closes: #68)
84 * Fix potential endless loop in dns label unpacking code (Closes: #84)
85 * Fix bogus assertion in client-publish-service.c example
86 * Mild fix to some doxygen docs for avahi-common/address.h
87 * Fix passing in custom priviledged group (previously ignored setting)
90 This release is backwards compatible with Avahi 0.6.x with x < 16.

98 and not another process.
99 * Fix build on NetBSD (thanks to Daniel S. Haischt)
100 * Fix dbus_service_browser not setting AVAHI_LOOKUP_RESULT_OUR_OWN.
102 This release is backwards compatible with Avahi 0.6.x with x < 15.
107 This release fixes some bugs and includes a new component.
111 * Add new daemon "avahi-autoipd" which is an implementation of
112 IPv4LL as defined in RFC3927, a technology for assigning link-local IP
113 addresses without DHCP server. The same functionality has been available on
114 Windows under the name APIPA. While it is not the first implemenatation of
115 this technology for Free operating systems it is clearly the most powerful
116 and hopefully even the most secure. (Because it chroot()s and drops
117 priviliges and suchlike) For more information, especially about packaging
118 this new tool for distributions, please make sure to read:
119 http://avahi.org/wiki/AvahiAutoipd
120 and of course the man page included in the tarball. For the rationale for
121 adding this program to the Avahi toolset please read this mailing list
123 http://lists.freedesktop.org/archives/avahi/2006-September/000863.html
124 * Fix a segfault in the code handling static host name registrations

132 * Other minor code cleanups
134 This release is backwards compatible with Avahi 0.6.x with x < 14.
136 Please note that this version doesn't compile on NetBSD, patches
139 Please note that avahi-autoipd is available on Linux only for
140 now. Patches welcome. It is recommended to pass --disable-autoipd to
141 "configure" on non-Linux operating systems, otherwise the build will
147 This release fixes some bugs and includes minor enhancements.
150 * Add a new D-Bus method for changing the mDNS host name during
151 runtime. This functionality is only available to members of the
152 UNIX group "netdev", which is the same access group that is
153 enforced by GNOME's NetworkManager daemon. Since NM will probably
154 be the most prominent user of this new method, we decided to limit
155 access to the same group. The access group can be set by passing
156 --with-avahi-priv-access-group= to "configure". If you need more
157 sophisticated access control you can freely edit
158 /etc/dbus/system.d/avahi-dbus.conf.
159 * Add a new utility "avahi-set-host-name" which is a command line
160 wrapper around the aforementioned SetHostName() method.
161 * Bonjour API compatibility library:
162 * Implement DNSServiceUpdateRecord()
163 * Allow passing NULL as callback function for
165 * Implement subtype registration in DNSServiceRegister() in a
166 way that is compatible with Bonjour.
167 * Update to newer copy of dns_sd.h
168 * If the host name changes update names of static services wich
170 * Don't build documentation about embedding the Avahi mDNS stack into
171 other programs by default. This is a feature used only by embedded
172 developers. Pass --enable-core-docs to "configure" to enable
173 building these docs, like in Avahi <= 0.6.12.
174 * Build Qt documentation only when Qt support is enabled in
175 the configuration. Same for GLib.
176 * Change algorithm used to find a new host name on conflict. In
177 Avahi <= 0.6.12 a conflicting host name of "foobar" would be
178 changed to the new name "foobar2". With 0.6.13 "foobar-2" will be
179 picked instead. This follows Bonjour's behaviour and has the
180 advantage not confusing people with regular host names ending in
182 * Don't disable all static services when SIGHUP is recieved.
183 * Fix build when Avahi is configured without Gtk+ but with Python
185 * Fix build on MacOS X
186 * Support using Solaris DBM instead of gdbm for the service type
187 database. The latter is still recommended
188 * Minor other fixes and documentation updates
190 This release is backwards compatible with Avahi 0.6.x with x < 13.
195 This is a bugfix and general cleanups release.
198 * Compatibility with newer D-Bus releases (0.9x)
199 * Compatibility with DBUS builds with --disable-checks
200 * Fix an error in the DBUS event loop wrapping which
201 caused the avahi client libraries to dispatch some events
202 too late when used with D-BUS 0.62 and newer.
203 * avahi-daemon: fix a minor memory leak in the DBUS code.
204 * avahi-glib: some GLIB adapter cleanups
205 * avahi-dnsconfd: fix segfault when passing an invalid command
207 * avahi-test: portability patches for Solaris
208 * avahi-browse: flush STDOUT after each line, making it useful
210 * update service type database
212 This release is backwards compatible with Avahi 0.6.x with x < 12.
217 This is a bugfix and portability release.
221 * avahi-sharp: fix a fatal error in object disposal code
222 * add a few new entries to the servivce type database
223 * fix potential crash when the daemon shuts down
224 * compatibility with newer autoconf versions
226 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
227 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
232 This is mostly a bugfix release. Two of the bugs fixed are security
233 sensitive: a remote denial-of-service vulnerability and a buffer
234 overflow that can allow local users to become the 'avahi' user. We do
235 not consider either of them major security threats.
237 The DoS vulnerability can be exploited from a local network only. It
238 is not worth much, though, since mDNS can easily be flooded with
239 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
240 provoking a name conflict in perfect accordance with the specs.
242 The buffer overflow is hard to exploit remotely, only local users can
243 become the 'avahi' user. In addition the user is trapped inside a
244 chroot() environment (at least on Linux).
246 Anyhow, our security assessments are possibly as buggy as our
249 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
252 * Fix a buffer overflow in avahi-core
253 * Refuse to process invalid UTF8 data
254 * Automatically reconnect to the DBUS if we're kicked. (Works only if
255 chroot() is disabled)
256 * Don't hit an assert() in the client libs when the Avahi daemon is
258 * Enumerate all service types in the database in the Service
259 Discovery Applet for Gnome
260 * Improve the Bonjour compatibility layer to make it survive
261 GnomeMeeting's broken usage
262 * Deal properly with local non-ASCII hostnames
263 * AMD64 and FreeBSD portability fixes
264 * Filter double DNS server entries in avahi-dnsconfd
265 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
266 * Ported to Solaris (incomplete)
267 * Add _airport._tcp to our service type database
269 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
270 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

288 This release fixes some bugs and adds a few new features. Users of 0.6.7,
291 * Fix broken parsing of static hosts file
292 * Improve out-of-the-box Debian support
293 * Add configuration option to allow mDNS over POINTOPOINT links.
294 This is a potential security hole and YMMV. See man page for details.
295 * Create $(localstatedir)/run on installation
297 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
298 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7.

305 * Add static hosts name mappings
306 * Work around kernel bugs regarding multicast group membership
307 * ia64 portability fixes
308 * Don't require X11 to run avahi-bookmarks
309 * API: Return AVAHI_ERR_IS_EMPTY when the user tries to commit an
311 * Improved Slackware and Fedora suppport
313 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,

332 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
333 0.6.3, 0.6.4 and 0.6.5.
338 This release fixes some bugs and adds a new API function.
340 * avahi-browse: properly show services that are removed from the
342 * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and
344 * add new API function avahi_nss_support() and DBUS function
345 IsNSSSupportAvailable() which may be used to detect whether
346 libc's gethostbyname() supports mDNS domain names.
347 * patch avahi-bookmarks to make use of
348 IsNSSSupportAvailable(). avahi-bookmarks will now generate links
349 with real hostnames instead of numeric IP addresses if mDNS support
350 is detected for gethostbyname().
351 * add init script for Mandriva Linux
352 * speed up avahi_client_free()
354 * install missing header thread-watch.h
355 * fix avahi-bookmarks to work with certain twisted versions
356 * fix record updating
357 * Use pkg-config's Requires.private directive where it makes sense
359 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
365 This is a bugfix release and adds a new event loop implementation to

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

512 - Add option to generate links with hostnames instead of IPs
514 Avahi 0.2, the 'Dzień Dobry' release
515 ====================================
517 * Unfortunately this release broke the API/ABI of libavahi-client
518 with the following function removals
520 Removal of these functions may affect users of the 0.1 API
521 - avahi_service_resolver_block()
523 The following functions were simply for debugging information
524 and their removal should not affect anyone
525 - avahi_entry_group_get_dbus_path()

531 API itself has only had additions and no existing definitions
534 * avahi-daemon will now ignore local IP addresses with the "link" scope
535 unless it is the only IP address on the interface.
536 * avahi-daemon will no longer fail to start if D-BUS is not
537 available (if configured with enable-dbus=warn)
538 * Fixed a potential crasher when resolving things in libavahi-core.

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