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 * Add man page for bssh/bvnc
11 * avahi-ui: fix segfault when browsing in empty domains
12 * avahi-ui: allow GTK_RESPONSE_OK, _YES and _APPLY besides _ACCEPT as

15 * Don't pick the first and the last 256 IP addresses from the IPV4LL
16 range in avahi-autoipd, as required by RC3927 section 2.1
17 * No longer publish the Avahi service identification cookie anymore
18 by default. It was a bad idea in the first place. A better
19 replacement will hopefully be made available in Avahi eventually.
20 * Properly set umask before writing to /var/lib/avahi-autoipd
21 * Update .deskop files to work around KDE menu issue
22 * Various build fixes and other minor fixes and updates
24 This release is backwards compatible with Avahi 0.6.x with x < 19.
29 This is a bugfix release, adds a few new features and includes a new
32 * Add a new library libavahi-ui which contains a standard Gtk dialog
33 for browsing for services, and a new tool "zssh" that makes use of
34 it, which allows browsing for SSH and VNC servers and starts ssh or
35 xvncviewer if one item is selected.
36 * avahi-autoipd has been ported to FreeBSD (original patch from Bruce M Simpson)
37 * Improve OpenBSD, Solaris, MacOS X compatibility
38 * Linux inotify support for monitoring /etc/avahi/services/ and
39 /etc/avahi/hosts for changes. (Original patch from "behanw")

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

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

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

133 * Other minor code cleanups
135 This release is backwards compatible with Avahi 0.6.x with x < 14.
137 Please note that this version doesn't compile on NetBSD, patches
140 Please note that avahi-autoipd is available on Linux only for
141 now. Patches welcome. It is recommended to pass --disable-autoipd to
142 "configure" on non-Linux operating systems, otherwise the build will
148 This release fixes some bugs and includes minor enhancements.
151 * Add a new D-Bus method for changing the mDNS host name during
152 runtime. This functionality is only available to members of the
153 UNIX group "netdev", which is the same access group that is
154 enforced by GNOME's NetworkManager daemon. Since NM will probably
155 be the most prominent user of this new method, we decided to limit
156 access to the same group. The access group can be set by passing
157 --with-avahi-priv-access-group= to "configure". If you need more
158 sophisticated access control you can freely edit
159 /etc/dbus/system.d/avahi-dbus.conf.
160 * Add a new utility "avahi-set-host-name" which is a command line
161 wrapper around the aforementioned SetHostName() method.
162 * Bonjour API compatibility library:
163 * Implement DNSServiceUpdateRecord()
164 * Allow passing NULL as callback function for
166 * Implement subtype registration in DNSServiceRegister() in a
167 way that is compatible with Bonjour.
168 * Update to newer copy of dns_sd.h
169 * If the host name changes update names of static services wich
171 * Don't build documentation about embedding the Avahi mDNS stack into
172 other programs by default. This is a feature used only by embedded
173 developers. Pass --enable-core-docs to "configure" to enable
174 building these docs, like in Avahi <= 0.6.12.
175 * Build Qt documentation only when Qt support is enabled in
176 the configuration. Same for GLib.
177 * Change algorithm used to find a new host name on conflict. In
178 Avahi <= 0.6.12 a conflicting host name of "foobar" would be
179 changed to the new name "foobar2". With 0.6.13 "foobar-2" will be
180 picked instead. This follows Bonjour's behaviour and has the
181 advantage not confusing people with regular host names ending in
183 * Don't disable all static services when SIGHUP is recieved.
184 * Fix build when Avahi is configured without Gtk+ but with Python
186 * Fix build on MacOS X
187 * Support using Solaris DBM instead of gdbm for the service type
188 database. The latter is still recommended
189 * Minor other fixes and documentation updates
191 This release is backwards compatible with Avahi 0.6.x with x < 13.
196 This is a bugfix and general cleanups release.
199 * Compatibility with newer D-Bus releases (0.9x)
200 * Compatibility with DBUS builds with --disable-checks
201 * Fix an error in the DBUS event loop wrapping which
202 caused the avahi client libraries to dispatch some events
203 too late when used with D-BUS 0.62 and newer.
204 * avahi-daemon: fix a minor memory leak in the DBUS code.
205 * avahi-glib: some GLIB adapter cleanups
206 * avahi-dnsconfd: fix segfault when passing an invalid command
208 * avahi-test: portability patches for Solaris
209 * avahi-browse: flush STDOUT after each line, making it useful
211 * update service type database
213 This release is backwards compatible with Avahi 0.6.x with x < 12.
218 This is a bugfix and portability release.
222 * avahi-sharp: fix a fatal error in object disposal code
223 * add a few new entries to the servivce type database
224 * fix potential crash when the daemon shuts down
225 * compatibility with newer autoconf versions
227 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
228 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
233 This is mostly a bugfix release. Two of the bugs fixed are security
234 sensitive: a remote denial-of-service vulnerability and a buffer
235 overflow that can allow local users to become the 'avahi' user. We do
236 not consider either of them major security threats.
238 The DoS vulnerability can be exploited from a local network only. It
239 is not worth much, though, since mDNS can easily be flooded with
240 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
241 provoking a name conflict in perfect accordance with the specs.
243 The buffer overflow is hard to exploit remotely, only local users can
244 become the 'avahi' user. In addition the user is trapped inside a
245 chroot() environment (at least on Linux).
247 Anyhow, our security assessments are possibly as buggy as our
250 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
253 * Fix a buffer overflow in avahi-core
254 * Refuse to process invalid UTF8 data
255 * Automatically reconnect to the DBUS if we're kicked. (Works only if
256 chroot() is disabled)
257 * Don't hit an assert() in the client libs when the Avahi daemon is
259 * Enumerate all service types in the database in the Service
260 Discovery Applet for Gnome
261 * Improve the Bonjour compatibility layer to make it survive
262 GnomeMeeting's broken usage
263 * Deal properly with local non-ASCII hostnames
264 * AMD64 and FreeBSD portability fixes
265 * Filter double DNS server entries in avahi-dnsconfd
266 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
267 * Ported to Solaris (incomplete)
268 * Add _airport._tcp to our service type database
270 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
271 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

289 This release fixes some bugs and adds a few new features. Users of 0.6.7,
292 * Fix broken parsing of static hosts file
293 * Improve out-of-the-box Debian support
294 * Add configuration option to allow mDNS over POINTOPOINT links.
295 This is a potential security hole and YMMV. See man page for details.
296 * Create $(localstatedir)/run on installation
298 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
299 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7.

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

333 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
334 0.6.3, 0.6.4 and 0.6.5.
339 This release fixes some bugs and adds a new API function.
341 * avahi-browse: properly show services that are removed from the
343 * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and
345 * add new API function avahi_nss_support() and DBUS function
346 IsNSSSupportAvailable() which may be used to detect whether
347 libc's gethostbyname() supports mDNS domain names.
348 * patch avahi-bookmarks to make use of
349 IsNSSSupportAvailable(). avahi-bookmarks will now generate links
350 with real hostnames instead of numeric IP addresses if mDNS support
351 is detected for gethostbyname().
352 * add init script for Mandriva Linux
353 * speed up avahi_client_free()
355 * install missing header thread-watch.h
356 * fix avahi-bookmarks to work with certain twisted versions
357 * fix record updating
358 * Use pkg-config's Requires.private directive where it makes sense
360 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,

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

513 - Add option to generate links with hostnames instead of IPs
515 Avahi 0.2, the 'Dzień Dobry' release
516 ====================================
518 * Unfortunately this release broke the API/ABI of libavahi-client
519 with the following function removals
521 Removal of these functions may affect users of the 0.1 API
522 - avahi_service_resolver_block()
524 The following functions were simply for debugging information
525 and their removal should not affect anyone
526 - avahi_entry_group_get_dbus_path()

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

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