9 * add a few new entries to the servivce type database
10 * fix potential crash when the daemon shuts down
11 * compatibility with newer autoconf versions
13 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
14 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
19 This is mostly a bugfix release. Two of the bugs fixed are security
20 sensitive: a remote denial-of-service vulnerability and a buffer
21 overflow that can allow local users to become the 'avahi' user. We do
22 not consider either of them major security threats.
24 The DoS vulnerability can be exploited from a local network only. It
25 is not worth much, though, since mDNS can easily be flooded with
26 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
27 provoking a name conflict in perfect accordance with the specs.
29 The buffer overflow is hard to exploit remotely, only local users can
30 become the 'avahi' user. In addition the user is trapped inside a
31 chroot() environment (at least on Linux).
33 Anyhow, our security assessments are possibly as buggy as our

200 http://avahi.org/chrome/site/avahi-trac.png
205 This is mostly a bugfix release.

211 * Add DBUS API versioning through the new method GetAPIVersion()
212 * Build the HOWL compatibility library as "libhowl.so", instead of
213 "libavahi-compat-howl.so". This will help distributors to ensure
214 full API/ABI compatibility with HOWL out-of-the-box.
215 * Same for the Bonjour compatibility library
218 We encourage Linux users to update to libdaemon 0.10 since logging
219 does not work from a chroot() environment with older versions.
221 This release is fully API and ABI compatible with Avahi 0.6. This is
222 true for both the C libraries and the DBUS interface.
224 Packagers should read the new documentation file doc/COMPAT-LAYERS
225 which contains some information about maintaining full build system
226 compatibility in addition to ABI/API compatibility.
228 Avahi 0.6, the "Goddag" release
229 ===============================
231 * Support for (read-only) wide area support. (i.e. DNS-SD over unicast DNS)

266 any CLI language such as C#

279 * Renamed the include dirs for the Qt bindings to include the
280 version number, as they may diverge in future.

301 Avahi 0.2, the 'Dzień Dobry' release
302 ====================================
304 * Unfortunately this release broke the API/ABI of libavahi-client
305 with the following function removals
307 Removal of these functions may affect users of the 0.1 API
308 - avahi_service_resolver_block()
310 The following functions were simply for debugging information
311 and their removal should not affect anyone
312 - avahi_entry_group_get_dbus_path()
313 - avahi_domain_browser_get_dbus_path()
314 - avahi_service_type_browser_get_dbus_path()

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

332 * Fixed a typo in avahi-glib.pc that stopped programs using
333 the GLIB api from compiling correctly
334 * A critical bug in the reflector was fixed where it may go into a
335 state of constantly flooding queries out to the network.

341 * Fixed a critical bug where you cannot use more than one AvahiClient
342 or use it in an application already using D-BUS
343 * Fixed assembly of empty string lists to RFC compliant TXT records
344 * Added a new service type description database with human
345 understandable descriptions of services with translations.

348 if the process or machine has been suspended
349 * Fixed compilation and runtime issues on 64-bit distributions
353 Avahi 0.1, the "Guten Tag" release
354 ==================================
356 The Avahi team would like to announce the immediate availability of
357 Avahi 0.1 "Guten Tag".
359 Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
360 It allows programs to publish and discover services and hosts
361 running on a local network with no specific configuration. For
362 example you can plug into a network and instantly find printers to
363 print to, files to look at and people to talk to.
365 Avahi is designed to be compatible with the mDNS/DNS-SD specification
366 and boasts the following features
368 * Fully open source and freely available under the LGPL
369 * Full IPv4 and IPv6 support
370 * An embeddable mDNS stack
371 * Dynamic adjustment to network reconfiguration
372 * Daemon with DBUS API for desktop applications
373 * C library to interface with the DBUS API
374 * Compatible with other mDNS/DNS-SD implementations such as
375 Howl and Apple Bonjour (previously Rendezvous)
376 * Ability to correctly "reflect" mDNS between two or more LAN segments
377 * Ability to configure DNS servers based on mDNS/DNS-SD published
378 information, a feature that is very usefull on IPv6
379 which has no other mechanism for this.
380 * Combined with nss-mdns, allows hostname lookup such as
381 'laptop.local' without the configuration of a DNS server.
382 http://0pointer.de/lennart/projects/nss-mdns/
383 * Easy integration into GLIB, GTK other mainloop applications.
384 * Documentation and examples of both developer APIs and utilities.
386 mDNS/DNS-SD is part of a larger set of specifications for easy
387 configuration of networking known as "ZeroConf"
388 (http://www.zeroconf.org/), with the aim of allowing you to plug into
389 a network and instantly be able to interact with it's services.
391 Avahi was designed to be a fully free implementation, and is
392 available under the LGPL. Many other implementations of the mDNS/DNS-SD
393 specification were previously non-free, restricting their use in many
394 platforms such as the GNOME desktop and many distributions.
396 While Avahi is a 0.1 release, we feel it is feature complete and
397 available for immediate use, developers can make use of the Avahi
398 client library to provide above mentioned functionality in their
