4 This release fixes some bugs and includes minor enhancements.
7 * Add a new D-Bus method for changing the mDNS host name during
8 runtime. This functionality is only available to members of the
9 UNIX group "netdev", which is the same access group that is
10 enforced by GNOME's NetworkManager daemon. Since NM will probably
11 be the most prominent user of this new method, we decided to limit
12 access to the same group. The access group can be set by passing
13 --with-avahi-priv-access-group= to "configure". If you need more
14 sophisticated access control you can freely edit
15 /etc/dbus/system.d/avahi-dbus.conf.
16 * Add a new utility "avahi-set-host-name" which is a command line
17 wrapper around the aforementioned SetHostName() method.
18 * Bonjour API compatibility library:
19 * Implement DNSServiceUpdateRecord()
20 * Allow passing NULL as callback function for
22 * Implement subtype registration in DNSServiceRegister() in a
23 way that is compatible with Bonjour.
24 * Update to newer copy of dns_sd.h
25 * If the host name changes update names of static services wich
27 * Don't build documentation about embedding the Avahi mDNS stack into
28 other programs by default. This is a feature used only by embedded
29 developers. Pass --enable-core-docs to "configure" to enable
30 building these docs, like in Avahi <= 0.6.12.
31 * Build Qt documentation only when Qt support is enabled in
32 the configuration. Same for GLib.
33 * Change algorithm used to find a new host name on conflict. In
34 Avahi <= 0.6.12 a conflicting host name of "foobar" would be
35 changed to the new name "foobar2". With 0.6.13 "foobar-2" will be
36 picked instead. This follows Bonjour's behaviour and has the
37 advantage not confusing people with regular host names ending in
39 * Don't disable all static services when SIGHUP is recieved.
40 * Fix build when Avahi is configured without Gtk+ but with Python
42 * Fix build on MacOS X
43 * Support using Solaris DBM instead of gdbm for the service type
44 database. The latter is still recommended
45 * Minor other fixes and documentation updates
47 This release is backwards compatible with Avahi 0.6.x with x < 13.
52 This is a bugfix and general cleanups release.
55 * Compatibility with newer D-Bus releases (0.9x)
56 * Compatibility with DBUS builds with --disable-checks
57 * Fix an error in the DBUS event loop wrapping which
58 caused the avahi client libraries to dispatch some events
59 too late when used with D-BUS 0.62 and newer.
60 * avahi-daemon: fix a minor memory leak in the DBUS code.
61 * avahi-glib: some GLIB adapter cleanups
62 * avahi-dnsconfd: fix segfault when passing an invalid command
64 * avahi-test: portability patches for Solaris
65 * avahi-browse: flush STDOUT after each line, making it useful
67 * update service type database
69 This release is backwards compatible with Avahi 0.6.x with x < 12.
74 This is a bugfix and portability release.
78 * avahi-sharp: fix a fatal error in object disposal code
79 * add a few new entries to the servivce type database
80 * fix potential crash when the daemon shuts down
81 * compatibility with newer autoconf versions
83 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
84 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
89 This is mostly a bugfix release. Two of the bugs fixed are security
90 sensitive: a remote denial-of-service vulnerability and a buffer
91 overflow that can allow local users to become the 'avahi' user. We do
92 not consider either of them major security threats.
94 The DoS vulnerability can be exploited from a local network only. It
95 is not worth much, though, since mDNS can easily be flooded with
96 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
97 provoking a name conflict in perfect accordance with the specs.
99 The buffer overflow is hard to exploit remotely, only local users can
100 become the 'avahi' user. In addition the user is trapped inside a
101 chroot() environment (at least on Linux).
103 Anyhow, our security assessments are possibly as buggy as our
106 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
109 * Fix a buffer overflow in avahi-core
110 * Refuse to process invalid UTF8 data
111 * Automatically reconnect to the DBUS if we're kicked. (Works only if
112 chroot() is disabled)
113 * Don't hit an assert() in the client libs when the Avahi daemon is
115 * Enumerate all service types in the database in the Service
116 Discovery Applet for Gnome

122 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
123 * Ported to Solaris (incomplete)
124 * Add _airport._tcp to our service type database
126 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
127 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

197 * avahi-browse: properly show services that are removed from the
199 * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and
201 * add new API function avahi_nss_support() and DBUS function
202 IsNSSSupportAvailable() which may be used to detect whether
203 libc's gethostbyname() supports mDNS domain names.
204 * patch avahi-bookmarks to make use of
205 IsNSSSupportAvailable(). avahi-bookmarks will now generate links
206 with real hostnames instead of numeric IP addresses if mDNS support
207 is detected for gethostbyname().
208 * add init script for Mandriva Linux
209 * speed up avahi_client_free()

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

265 This release is both up and downwards compatible with Avahi 0.6 and 0.6.1.
267 Avahi now has its own Domain (http://avahi.org) and a new Website!
269 And, most importantly, we now have a Logo:
270 http://avahi.org/chrome/site/avahi-trac.png
275 This is mostly a bugfix release.
277 * Fix a segfault when shutting down the daemon. Please note that this
278 issue was not security sensitive in any way but had the ugly side
279 effect that the daemon's PID file was not removed properly.
280 * Added init scripts for ArchLinux and FreeBSD
281 * Add DBUS API versioning through the new method GetAPIVersion()
282 * Build the HOWL compatibility library as "libhowl.so", instead of
283 "libavahi-compat-howl.so". This will help distributors to ensure
284 full API/ABI compatibility with HOWL out-of-the-box.
285 * Same for the Bonjour compatibility library
288 We encourage Linux users to update to libdaemon 0.10 since logging
289 does not work from a chroot() environment with older versions.
291 This release is fully API and ABI compatible with Avahi 0.6. This is
292 true for both the C libraries and the DBUS interface.
294 Packagers should read the new documentation file doc/COMPAT-LAYERS
295 which contains some information about maintaining full build system
296 compatibility in addition to ABI/API compatibility.

375 with the following function removals
377 Removal of these functions may affect users of the 0.1 API
378 - avahi_service_resolver_block()
380 The following functions were simply for debugging information
381 and their removal should not affect anyone
382 - avahi_entry_group_get_dbus_path()

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

419 * Fixed compilation and runtime issues on 64-bit distributions
423 Avahi 0.1, the "Guten Tag" release
424 ==================================
426 The Avahi team would like to announce the immediate availability of
427 Avahi 0.1 "Guten Tag".
429 Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
430 It allows programs to publish and discover services and hosts
431 running on a local network with no specific configuration. For
432 example you can plug into a network and instantly find printers to
433 print to, files to look at and people to talk to.
435 Avahi is designed to be compatible with the mDNS/DNS-SD specification
436 and boasts the following features
438 * Fully open source and freely available under the LGPL
439 * Full IPv4 and IPv6 support
440 * An embeddable mDNS stack
441 * Dynamic adjustment to network reconfiguration
442 * Daemon with DBUS API for desktop applications
443 * C library to interface with the DBUS API
444 * Compatible with other mDNS/DNS-SD implementations such as
445 Howl and Apple Bonjour (previously Rendezvous)
446 * Ability to correctly "reflect" mDNS between two or more LAN segments
447 * Ability to configure DNS servers based on mDNS/DNS-SD published
448 information, a feature that is very usefull on IPv6
449 which has no other mechanism for this.
450 * Combined with nss-mdns, allows hostname lookup such as
451 'laptop.local' without the configuration of a DNS server.
452 http://0pointer.de/lennart/projects/nss-mdns/
453 * Easy integration into GLIB, GTK other mainloop applications.
454 * Documentation and examples of both developer APIs and utilities.
456 mDNS/DNS-SD is part of a larger set of specifications for easy
457 configuration of networking known as "ZeroConf"
458 (http://www.zeroconf.org/), with the aim of allowing you to plug into
459 a network and instantly be able to interact with it's services.
461 Avahi was designed to be a fully free implementation, and is
462 available under the LGPL. Many other implementations of the mDNS/DNS-SD
463 specification were previously non-free, restricting their use in many
464 platforms such as the GNOME desktop and many distributions.
466 While Avahi is a 0.1 release, we feel it is feature complete and
467 available for immediate use, developers can make use of the Avahi
468 client library to provide above mentioned functionality in their
471 We unfortunately do not have a logo yet! We would love if someone
472 could suggest ideas for a logo or even design us one. If you think
