BREAKING CHANGE: zeroconf.asyncio has been renamed zeroconf.aio (#503) @bdraco

The asyncio name could shadow system asyncio in some cases. If zeroconf is in sys.path, this would result in loading zeroconf.asyncio when system asyncio was intended.

BREAKING CHANGE: Update internal version check to match docs (3.6+) (#491) @bdraco

Python version eariler then 3.6 were likely broken with zeroconf already, however the version is now explictly checked.

BREAKING CHANGE: RecordUpdateListener now uses update_records instead of update_record (#419) @bdraco

This allows the listener to receive all the records that have been updated in a single transaction such as a packet or cache expiry.

update_record has been deprecated in favor of update_records A compatibility shim exists to ensure classes that use RecordUpdateListener as a base class continue to have update_record called, however they should be updated as soon as possible.

A new method update_records_complete is now called on each listener when all listeners have completed processing updates and the cache has been updated. This allows ServiceBrowsers to delay calling handlers until they are sure the cache has been updated as its a common pattern to call for ServiceInfo when a ServiceBrowser handler fires.

BREAKING CHANGE: Ensure listeners do not miss initial packets if Engine starts too quickly (#387) @bdraco

When manually creating a zeroconf.Engine object, it is no longer started automatically. It must manually be started by calling .start() on the created object.

The Engine thread is now started after all the listeners have been added to avoid a race condition where packets could be missed at startup.

BREAKING CHANGE: Remove DNSOutgoing.packet backwards compatibility (#569) @bdraco

DNSOutgoing.packet only returned a partial message when the DNSOutgoing contents exceeded _MAX_MSG_ABSOLUTE or _MAX_MSG_TYPICAL This was a legacy function that was replaced with .packets() which always returns a complete payload in #248 As packet() should not be used since it will end up missing data, it has been removed

MAJOR BUG: Ensure matching PTR queries are returned with the ANY query (#618) @bdraco

MAJOR BUG: Fix lookup of uppercase names in registry (#597) @bdraco

If the ServiceInfo was registered with an uppercase name and the query was for a lowercase name, it would not be found and vice-versa.

MAJOR BUG: Ensure unicast responses can be sent to any source port (#598) @bdraco

Unicast responses were only being sent if the source port was 53, this prevented responses when testing with dig:

dig -p 5353 @224.0.0.251 media-12.local

The above query will now see a response

AsyncServiceBrowser must recheck for handlers to call when holding condition (#483)

There was a short race condition window where the AsyncServiceBrowser could add to _handlers_to_call in the Engine thread, have the condition notify_all called, but since the AsyncServiceBrowser was not yet holding the condition it would not know to stop waiting and process the handlers to call.

Relocate ServiceBrowser wait time calculation to seperate function (#484) @bdraco
