-*-text-*-
A terse (and incomplete) list of API changes between 0.5.2 and 0.6:
* Most browsing and registration functions and their callbacks gained
new "flags" parameters. Passing 0 results in similar behaviour as
in 0.5.2
* avahi-client/client.h has been split into client.h, publish.h and lookup.h
* avahi-core/core.h has been split into core.h publish.h lookup.h
* avahi_client_is_service_local() has been removed. Use instead the special
flags AVAHI_LOOKUP_RESULT_LOCAL and AVAHI_LOOKUP_RESULT_OUR_OWN which are
set when resolving or browsing for services. AVAHI_LOOKUP_RESULT_OUR_OWN is
what most people should use.
* AVAHI_RESOLVER_TIMEOUT and AVAHI_RESOLVER_NOT_FOUND have been
removed. Instead AVAHI_RESOLVER_FAILURE is used and the exact error
code is available from avahi_client_errno()/avahi_server_errno()
* The events AVAHI_BROWSER_CACHE_EXHAUSTED, AVAHI_BROWSER_ALL_FOR_NOW
have been introduced. Failures during browsing are now passed as
AVAHI_BROWSER_FAILURE and the error code is made available through
avahi_client_errno()/avahi_server_errno().
* The server gained a new state AVAHI_SERVER_FAILURE if some fatal
error happens. The reason can be found in
avahi_server_errno(). Clients can safely ignore this state.
* You can now update existing records by setting the
AVAHI_PUBLISH_UPDATE flags for add_service() and friends. Consider
using avahi_server_update_service_txt_strlst() if you need to
update only the TXT record for a service.
* Proper support for service subtypes is now available. Use
avahi_server_add_service_subtype() for that.
* Entry groups gained the new state AVAHI_ENTRY_GROUP_FAILURE. The
reason is available using
avahi_server_errno()/avahi_client_errno().
* Many superfluous functions have been removed from the public API or
entirely.
* avahi_simple_poll_iterate() has been split up into three
functions. avahi_simple_poll_loop() has been introduced.
* Some new limits have been introduced: AVAHI_ADDRESS_STR_MAX,
AVAHI_DOMAIN_NAME_MAX, AVAHI_LABEL_MAX
* The functions avahi_service_name_join() and
avahi_service_name_split() have been introduced.
* AVAHI_ERR_LOCAL_COLLISION has been renamed to AVAHI_ERR_COLLSION
* The values of AVAHI_PROTO_xxx have changed, they are no longer
identical to the BSD AF_xxx constants
* avahi_client_new() now takes an additional flags parameter. Most
interesting flag here is AVAHI_CLIENT_NO_FAIL, which can be used to
create an AvahiClient object even when the daemon is not
running. This is useful to deal with daemon restarts.
* AvahiClient gained a new state AVAHI_CLIENT_FAILURE. (superseding
AVAHI_CLIENT_DISCONNECTED). If this event happens,
avahi_client_errno() will return the reason. If the error returned
is AVAHI_ERR_DISCONNECTED, the situation where
AVAHI_CLIENT_DISCONNECTED was previously thrown is entered. You may
choose to reconnect in that case by freeing your AvahiClient new
and create a new one with passing AVAHI_CLIENT_NO_FAIL.
* There's now a client side AvahiRecordBrowser, and
avahi_entry_group_add_record().
