This is a new features release. It offers quite a bit of change over the
|
||
|
|
previous version. More details of the new features can be found in the
|
||
|
|
[man pages].
|
||
|
|
|
||
|
|
The substantial changes are:
|
||
|
|
|
||
|
|
* Basic support for connecting multiple MQTT brokers together (bridging).
|
||
|
|
* mosquitto_sub can now subscribe to multiple topics (limited to a global
|
||
|
|
QoS).
|
||
|
|
* mosquitto_pub can now send a file as a message.
|
||
|
|
* mosquitto_pub can now read all of stdin and send it as a message.
|
||
|
|
* mosquitto_pub can now read stdin and send each line as a message.
|
||
|
|
* Implement a more efficient database design, so that only one copy of each
|
||
|
|
message is held in the database, rather than one per subscribed client.
|
||
|
|
* Add support for automatic upgrading of the mosquitto DB from v1 to v2.
|
||
|
|
* If a retained message is received with a zero length payload, the retained
|
||
|
|
message for that topic is deleted.
|
||
|
|
* Implement the `max_inflight_messages` and `max_queued_messages` features in
|
||
|
|
the broker.
|
||
|
|
|
||
|
|
The less visible features and bug fixes are as follows:
|
||
|
|
|
||
|
|
* Add support for disabling `clean session` for the sub client.
|
||
|
|
* mosquitto will now correctly run VACUUM on the persistent database on exit.
|
||
|
|
* Add the `store_cleanup_interval` config option for dealing with the internal
|
||
|
|
message store.
|
||
|
|
* Add `persistence_file` config option to allow changing the filename of the
|
||
|
|
persistence database. This allows multiple mosquitto DBs to be stored in the
|
||
|
|
same location whilst keeping `persistence_location` compatible with rsmb.
|
||
|
|
* Don't store QoS=0 messages for disconnected clients. Fixes bug #572608. This
|
||
|
|
wasn't correctly fixed in version 0.5.
|
||
|
|
* Don't disconnect clients if they send a PUBLISH with zero length payload
|
||
|
|
(bug #573610).
|
||
|
|
* Send through zero length messages.
|
||
|
|
* Produce a warning on unsupported rsmb options instead of quitting.
|
||
|
|
* Describe clean session flag in the mqtt man page.
