-*-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().
