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