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

172 * AMD64 and FreeBSD portability fixes
173 * Filter double DNS server entries in avahi-dnsconfd
174 * Fix a locking bug in avahi-sharp's EntryGroup.AddService()
175 * Ported to Solaris (incomplete)
176 * Add _airport._tcp to our service type database
178 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
179 0.6.3, 0.6.4, 0.6.5, 0.6.6, 0.6.7, 0.6.8 and 0.6.9.

197 This release fixes some bugs and adds a few new features. Users of 0.6.7,
200 * Fix broken parsing of static hosts file
201 * Improve out-of-the-box Debian support
202 * Add configuration option to allow mDNS over POINTOPOINT links.
203 This is a potential security hole and YMMV. See man page for details.
204 * Create $(localstatedir)/run on installation
206 This release is backwards compatible with Avahi 0.6, 0.6.1, 0.6.2,
207 0.6.3, 0.6.4, 0.6.5, 0.6.6 and 0.6.7.

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

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

285 A quick introduction how to use the new AvahiThreadedPool interface is
286 available in our Wiki:
288 http://avahi.org/wiki/RunningAvahiClientAsThread
293 This is a bugfix release. Everyone should update ASAP!
295 * avahi-sharp: make sure to append a trailing NUL byte to all C strings
296 * avahi-core: fix a double free() which occurs when wide area lookups timeout
298 This release is fully compatible with Avahi 0.6, 0.6.1 and 0.6.2.
303 This is mostly a bugfix release.
305 * Compatibility with DBUS 0.60 (Full compatibility with DBUS 0.3x and
307 * Fix introspection for some auxiliary DBUS objects
308 * Miscellaneous documentation updates
309 * Improve Autoconf support for detecting PTHREADS library
310 * Fix avahi-publish --help
311 * Workaround a DBUS limitation which might cause Avahi to die when a
312 user sends an empty TXT entry over DBUS
313 * Increase number of resolver/browser objects a DBUS client may create
314 * Remove fprintf() call in avahi_client_new()
317 This release is both up and downwards compatible with Avahi 0.6 and 0.6.1.
319 Avahi now has its own Domain (http://avahi.org) and a new Website!
321 And, most importantly, we now have a Logo:
322 http://avahi.org/chrome/site/avahi-trac.png
327 This is mostly a bugfix release.
329 * Fix a segfault when shutting down the daemon. Please note that this
330 issue was not security sensitive in any way but had the ugly side
331 effect that the daemon's PID file was not removed properly.
332 * Added init scripts for ArchLinux and FreeBSD
333 * Add DBUS API versioning through the new method GetAPIVersion()
334 * Build the HOWL compatibility library as "libhowl.so", instead of
335 "libavahi-compat-howl.so". This will help distributors to ensure
336 full API/ABI compatibility with HOWL out-of-the-box.
337 * Same for the Bonjour compatibility library
340 We encourage Linux users to update to libdaemon 0.10 since logging
341 does not work from a chroot() environment with older versions.
343 This release is fully API and ABI compatible with Avahi 0.6. This is
344 true for both the C libraries and the DBUS interface.
346 Packagers should read the new documentation file doc/COMPAT-LAYERS
347 which contains some information about maintaining full build system
348 compatibility in addition to ABI/API compatibility.

421 - Add option to generate links with hostnames instead of IPs
423 Avahi 0.2, the 'Dzień Dobry' release
424 ====================================
426 * Unfortunately this release broke the API/ABI of libavahi-client
427 with the following function removals
429 Removal of these functions may affect users of the 0.1 API
430 - avahi_service_resolver_block()
432 The following functions were simply for debugging information
433 and their removal should not affect anyone
434 - avahi_entry_group_get_dbus_path()

440 API itself has only had additions and no existing definitions
443 * avahi-daemon will now ignore local IP addresses with the "link" scope
444 unless it is the only IP address on the interface.
445 * avahi-daemon will no longer fail to start if D-BUS is not
446 available (if configured with enable-dbus=warn)
447 * Fixed a potential crasher when resolving things in libavahi-core.

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

460 in addition to the ServiceResolver provided in 0.1
461 * Added support for Arch and Gentoo linux distributions.
462 * Allowed configuration on non-supported distributions

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