4 This release fixes some bugs and includes a new component.
8 * Add new daemon "avahi-autoipd" which is an implementation of
9 IPv4LL as defined in RFC3927, a technology for assigning link-local IP
10 addresses without DHCP server. The same functionality has been available on
11 Windows under the name APIPA. While it is not the first implemenatation of
12 this technology for Free operating systems it is clearly the most powerful
13 and hopefully even the most secure. (Because it chroot()s and drops
14 priviliges and suchlike) For more information, especially about packaging
15 this new tool for distributions, please make sure to read:
16 http://avahi.org/wiki/AvahiAutoipd
17 and of course the man page included in the tarball. For the rationale for
18 adding this program to the Avahi toolset please read this mailing list
20 http://lists.freedesktop.org/archives/avahi/2006-September/000863.html
21 * Fix a segfault in the code handling static host name registrations
22 * Add a few new entries to the service type database
24 * Documentation updates
25 * Fix service type database building on Solaris
26 * Make use of newer D-Bus APIs
27 * Fix random seed initialization
28 * Install SFTP static service file by default
29 * Other minor code cleanups
31 This release is backwards compatible with Avahi 0.6.x with x < 14.
33 Please note that this version doesn't compile on NetBSD, patches
36 Please note that avahi-autoipd is available on Linux only for
37 now. Patches welcome. It is recommended to pass --disable-autoipd to
38 "configure" on non-Linux operating systems, otherwise the build will
44 This release fixes some bugs and includes minor enhancements.
47 * Add a new D-Bus method for changing the mDNS host name during
48 runtime. This functionality is only available to members of the
49 UNIX group "netdev", which is the same access group that is
50 enforced by GNOME's NetworkManager daemon. Since NM will probably
51 be the most prominent user of this new method, we decided to limit
52 access to the same group. The access group can be set by passing
53 --with-avahi-priv-access-group= to "configure". If you need more
54 sophisticated access control you can freely edit
55 /etc/dbus/system.d/avahi-dbus.conf.
56 * Add a new utility "avahi-set-host-name" which is a command line
57 wrapper around the aforementioned SetHostName() method.
58 * Bonjour API compatibility library:
59 * Implement DNSServiceUpdateRecord()
60 * Allow passing NULL as callback function for
62 * Implement subtype registration in DNSServiceRegister() in a
63 way that is compatible with Bonjour.
64 * Update to newer copy of dns_sd.h
65 * If the host name changes update names of static services wich
67 * Don't build documentation about embedding the Avahi mDNS stack into
68 other programs by default. This is a feature used only by embedded
69 developers. Pass --enable-core-docs to "configure" to enable
70 building these docs, like in Avahi <= 0.6.12.
71 * Build Qt documentation only when Qt support is enabled in
72 the configuration. Same for GLib.
73 * Change algorithm used to find a new host name on conflict. In
74 Avahi <= 0.6.12 a conflicting host name of "foobar" would be
75 changed to the new name "foobar2". With 0.6.13 "foobar-2" will be
76 picked instead. This follows Bonjour's behaviour and has the
77 advantage not confusing people with regular host names ending in
79 * Don't disable all static services when SIGHUP is recieved.
80 * Fix build when Avahi is configured without Gtk+ but with Python
82 * Fix build on MacOS X
83 * Support using Solaris DBM instead of gdbm for the service type
84 database. The latter is still recommended
85 * Minor other fixes and documentation updates
87 This release is backwards compatible with Avahi 0.6.x with x < 13.
92 This is a bugfix and general cleanups release.
95 * Compatibility with newer D-Bus releases (0.9x)
96 * Compatibility with DBUS builds with --disable-checks
97 * Fix an error in the DBUS event loop wrapping which
98 caused the avahi client libraries to dispatch some events
99 too late when used with D-BUS 0.62 and newer.
100 * avahi-daemon: fix a minor memory leak in the DBUS code.
101 * avahi-glib: some GLIB adapter cleanups
102 * avahi-dnsconfd: fix segfault when passing an invalid command
104 * avahi-test: portability patches for Solaris
105 * avahi-browse: flush STDOUT after each line, making it useful
107 * update service type database
109 This release is backwards compatible with Avahi 0.6.x with x < 12.
114 This is a bugfix and portability release.
118 * avahi-sharp: fix a fatal error in object disposal code
119 * add a few new entries to the servivce type database
120 * fix potential crash when the daemon shuts down
121 * compatibility with newer autoconf versions
123 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
124 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.9 and 0.6.10.
129 This is mostly a bugfix release. Two of the bugs fixed are security
130 sensitive: a remote denial-of-service vulnerability and a buffer
131 overflow that can allow local users to become the 'avahi' user. We do
132 not consider either of them major security threats.
134 The DoS vulnerability can be exploited from a local network only. It
135 is not worth much, though, since mDNS can easily be flooded with
136 nonsense anyway. It is easy to kick remote mDNS/DNS-SD services by
137 provoking a name conflict in perfect accordance with the specs.
139 The buffer overflow is hard to exploit remotely, only local users can
140 become the 'avahi' user. In addition the user is trapped inside a
141 chroot() environment (at least on Linux).
143 Anyhow, our security assessments are possibly as buggy as our
146 *** PLEASE UPDATE YOUR INSTALLATION ASAP! ***
149 * Fix a buffer overflow in avahi-core
150 * Refuse to process invalid UTF8 data
151 * Automatically reconnect to the DBUS if we're kicked. (Works only if
152 chroot() is disabled)
153 * Don't hit an assert() in the client libs when the Avahi daemon is
155 * Enumerate all service types in the database in the Service
156 Discovery Applet for Gnome

162 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
163 * Ported to Solaris (incomplete)
164 * Add _airport._tcp to our service type database
166 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
167 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

188 * Fix broken parsing of static hosts file
189 * Improve out-of-the-box Debian support
190 * Add configuration option to allow mDNS over POINTOPOINT links.
191 This is a potential security hole and YMMV. See man page for details.
192 * Create $(localstatedir)/run on installation
194 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
195 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7.

230 0.6.3, 0.6.4 and 0.6.5.
235 This release fixes some bugs and adds a new API function.
237 * avahi-browse: properly show services that are removed from the
239 * fix build on bi-arch platforms, on GNU/kFreeBSD, on MIPS and
241 * add new API function avahi_nss_support() and DBUS function
242 IsNSSSupportAvailable() which may be used to detect whether
243 libc's gethostbyname() supports mDNS domain names.
244 * patch avahi-bookmarks to make use of
245 IsNSSSupportAvailable(). avahi-bookmarks will now generate links
246 with real hostnames instead of numeric IP addresses if mDNS support
247 is detected for gethostbyname().
248 * add init script for Mandriva Linux
249 * speed up avahi_client_free()
251 * install missing header thread-watch.h
252 * fix avahi-bookmarks to work with certain twisted versions

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

293 * Compatibility with DBUS 0.60 (Full compatibility with DBUS 0.3x and
295 * Fix introspection for some auxiliary DBUS objects
296 * Miscellaneous documentation updates
297 * Improve Autoconf support for detecting PTHREADS library
298 * Fix avahi-publish --help

301 * Increase number of resolver/browser objects a DBUS client may create
302 * Remove fprintf() call in avahi_client_new()
305 This release is both up and downwards compatible with Avahi 0.6 and 0.6.1.
307 Avahi now has its own Domain (http://avahi.org) and a new Website!
309 And, most importantly, we now have a Logo:
310 http://avahi.org/chrome/site/avahi-trac.png
315 This is mostly a bugfix release.
317 * Fix a segfault when shutting down the daemon. Please note that this
318 issue was not security sensitive in any way but had the ugly side
319 effect that the daemon's PID file was not removed properly.
320 * Added init scripts for ArchLinux and FreeBSD
321 * Add DBUS API versioning through the new method GetAPIVersion()
322 * Build the HOWL compatibility library as "libhowl.so", instead of
323 "libavahi-compat-howl.so". This will help distributors to ensure
324 full API/ABI compatibility with HOWL out-of-the-box.
325 * Same for the Bonjour compatibility library
328 We encourage Linux users to update to libdaemon 0.10 since logging
329 does not work from a chroot() environment with older versions.
331 This release is fully API and ABI compatible with Avahi 0.6. This is
332 true for both the C libraries and the DBUS interface.
334 Packagers should read the new documentation file doc/COMPAT-LAYERS
335 which contains some information about maintaining full build system
336 compatibility in addition to ABI/API compatibility.

411 Avahi 0.2, the 'Dzień Dobry' release
412 ====================================
414 * Unfortunately this release broke the API/ABI of libavahi-client
415 with the following function removals
417 Removal of these functions may affect users of the 0.1 API
418 - avahi_service_resolver_block()
420 The following functions were simply for debugging information
421 and their removal should not affect anyone
422 - avahi_entry_group_get_dbus_path()

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

459 * Fixed compilation and runtime issues on 64-bit distributions
463 Avahi 0.1, the "Guten Tag" release
464 ==================================
466 The Avahi team would like to announce the immediate availability of
467 Avahi 0.1 "Guten Tag".
469 Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
470 It allows programs to publish and discover services and hosts
471 running on a local network with no specific configuration. For
472 example you can plug into a network and instantly find printers to
473 print to, files to look at and people to talk to.
475 Avahi is designed to be compatible with the mDNS/DNS-SD specification
476 and boasts the following features
478 * Fully open source and freely available under the LGPL
479 * Full IPv4 and IPv6 support
480 * An embeddable mDNS stack
481 * Dynamic adjustment to network reconfiguration
482 * Daemon with DBUS API for desktop applications
483 * C library to interface with the DBUS API
484 * Compatible with other mDNS/DNS-SD implementations such as
485 Howl and Apple Bonjour (previously Rendezvous)
486 * Ability to correctly "reflect" mDNS between two or more LAN segments
487 * Ability to configure DNS servers based on mDNS/DNS-SD published
488 information, a feature that is very usefull on IPv6
489 which has no other mechanism for this.
490 * Combined with nss-mdns, allows hostname lookup such as
491 'laptop.local' without the configuration of a DNS server.
492 http://0pointer.de/lennart/projects/nss-mdns/
493 * Easy integration into GLIB, GTK other mainloop applications.
494 * Documentation and examples of both developer APIs and utilities.
496 mDNS/DNS-SD is part of a larger set of specifications for easy
497 configuration of networking known as "ZeroConf"
498 (http://www.zeroconf.org/), with the aim of allowing you to plug into
499 a network and instantly be able to interact with it's services.
501 Avahi was designed to be a fully free implementation, and is
502 available under the LGPL. Many other implementations of the mDNS/DNS-SD
503 specification were previously non-free, restricting their use in many
504 platforms such as the GNOME desktop and many distributions.
506 While Avahi is a 0.1 release, we feel it is feature complete and
507 available for immediate use, developers can make use of the Avahi
508 client library to provide above mentioned functionality in their
511 We unfortunately do not have a logo yet! We would love if someone
