3A terse (and incomplete) list of API changes between 0.5.2 and 0.6:
4
5 * Most browsing and registration functions and their callbacks gained
6   new "flags" parameters. Passing 0 results in similar behaviour as
7   in 0.5.2
8
9 * avahi-client/client.h has been split into client.h, publish.h and lookup.h
10 
11 * avahi-core/core.h has been split into core.h publish.h lookup.h
12
13 * avahi_client_is_service_local() has been removed. Use instead the special
14   flags AVAHI_LOOKUP_RESULT_LOCAL and AVAHI_LOOKUP_RESULT_OUR_OWN which are
15   set when resolving or browsing for services. AVAHI_LOOKUP_RESULT_OUR_OWN is
16   what most people should use.
17
18 * AVAHI_RESOLVER_TIMEOUT and AVAHI_RESOLVER_NOT_FOUND have been
19   removed. Instead AVAHI_RESOLVER_FAILURE is used and the exact error
20   code is available from avahi_client_errno()/avahi_server_errno()
21
22 * The events AVAHI_BROWSER_CACHE_EXHAUSTED, AVAHI_BROWSER_ALL_FOR_NOW
23   have been introduced. Failures during browsing are now passed as
24   AVAHI_BROWSER_FAILURE and the error code is made available through
25   avahi_client_errno()/avahi_server_errno().
26
27 * The server gained a new state AVAHI_SERVER_FAILURE if some fatal
28   error happens. The reason can be found in
29   avahi_server_errno(). Clients can safely ignore this state.
30
31 * You can now update existing records by setting the
32   AVAHI_PUBLISH_UPDATE flags for add_service() and friends. Consider
33   using avahi_server_update_service_txt_strlst() if you need to
34   update only the TXT record for a service.
35
36 * Proper support for service subtypes is now available. Use
37   avahi_server_add_service_subtype() for that.
38
39 * Entry groups gained the new state AVAHI_ENTRY_GROUP_FAILURE. The
40   reason is available using
41   avahi_server_errno()/avahi_client_errno().
42
43 * Many superfluous functions have been removed from the public API or
44   entirely.
45
46 * avahi_simple_poll_iterate() has been split up into three
47   functions. avahi_simple_poll_loop() has been introduced.
48
49 * Some new limits have been introduced: AVAHI_ADDRESS_STR_MAX,
50   AVAHI_DOMAIN_NAME_MAX, AVAHI_LABEL_MAX
51
52 * The functions avahi_service_name_join() and
53   avahi_service_name_split() have been introduced.
54 
55 * AVAHI_ERR_LOCAL_COLLISION has been renamed to AVAHI_ERR_COLLSION
56
57 * The values of AVAHI_PROTO_xxx have changed, they are no longer
58   identical to the BSD AF_xxx constants
59
60 * avahi_client_new() now takes an additional flags parameter. Most
61   interesting flag here is AVAHI_CLIENT_NO_FAIL, which can be used to
62   create an AvahiClient object even when the daemon is not
63   running. This is useful to deal with daemon restarts.
64
65 * AvahiClient gained a new state AVAHI_CLIENT_FAILURE.  (superseding
66   AVAHI_CLIENT_DISCONNECTED). If this event happens,
67   avahi_client_errno() will return the reason. If the error returned
68   is AVAHI_ERR_DISCONNECTED, the situation where
69   AVAHI_CLIENT_DISCONNECTED was previously thrown is entered. You may
70   choose to reconnect in that case by freeing your AvahiClient new
71   and create a new one with passing AVAHI_CLIENT_NO_FAIL.
72
73 * There's now a client side AvahiRecordBrowser, and 
74   avahi_entry_group_add_record().
