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 * Support using Solaris DBM instead of gdbm for the service type
43 database. The latter is still recommended
44 * Minor other fixes and documentation updates
46 This release is backwards compatible with Avahi 0.6.x with x < 13.
51 This is a bugfix and general cleanups release.
54 * Compatibility with newer D-Bus releases (0.9x)
55 * Compatibility with DBUS builds with --disable-checks
56 * Fix an error in the DBUS event loop wrapping which
57 caused the avahi client libraries to dispatch some events
58 too late when used with D-BUS 0.62 and newer.
59 * avahi-daemon: fix a minor memory leak in the DBUS code.
60 * avahi-glib: some GLIB adapter cleanups
61 * avahi-dnsconfd: fix segfault when passing an invalid command
63 * avahi-test: portability patches for Solaris
64 * avahi-browse: flush STDOUT after each line, making it useful
66 * update service type database
68 This release is backwards compatible with Avahi 0.6.x with x < 12.
73 This is a bugfix and portability release.
77 * avahi-sharp: fix a fatal error in object disposal code
78 * add a few new entries to the servivce type database
79 * fix potential crash when the daemon shuts down
80 * compatibility with newer autoconf versions
82 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
83 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
88 This is mostly a bugfix release. Two of the bugs fixed are security
89 sensitive: a remote denial-of-service vulnerability and a buffer
90 overflow that can allow local users to become the 'avahi' user. We do
91 not consider either of them major security threats.
93 The DoS vulnerability can be exploited from a local network only. It
94 is not worth much, though, since mDNS can easily be flooded with
95 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
96 provoking a name conflict in perfect accordance with the specs.
98 The buffer overflow is hard to exploit remotely, only local users can
99 become the 'avahi' user. In addition the user is trapped inside a
100 chroot() environment (at least on Linux).
102 Anyhow, our security assessments are possibly as buggy as our
105 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
108 * Fix a buffer overflow in avahi-core
109 * Refuse to process invalid UTF8 data
110 * Automatically reconnect to the DBUS if we're kicked. (Works only if
111 chroot() is disabled)
112 * Don't hit an assert() in the client libs when the Avahi daemon is
114 * Enumerate all service types in the database in the Service
115 Discovery Applet for Gnome
116 * Improve the Bonjour compatibility layer to make it survive
117 GnomeMeeting's broken usage
118 * Deal properly with local non-ASCII hostnames

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

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

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

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

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

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