This is a feature and bugfix release.

Broker

• Add $SYS/broker/messages/dropped
• Add $SYS/broker/clients/expired
• Replace $SYS/broker/+/per second/+ with moving average versions published at $SYS/broker/load/#
• Add $SYS/broker/load/sockets/+ and $SYS/broker/load/connections/+
• Documentation on password file format has been fixed.
• Disable SSL compression. This reduces memory usage significantly and removes the possibility of CRIME type attacks.
• Enable SSL_MODE_RELEASE_BUFFERS mode to reduce SSL memory usage further.
• Add allow_duplicate_messages option.
• ACL files can now have comment lines with # as the first character.
• Display message on startup about which config is being loaded.
• Fix max_inflight_messages and max_queued_messages not being applied.
• Fix documentation error in mosquitto.conf.
• Ensure that QoS 2 queued messages are sent out in a timely manner.
• Local bridges now act on clean_session correctly.
• Local bridges with clean_session==false now remove unused subscriptions on broker restart.
• The $SYS/broker/heap/# messages now no longer include "bytes" as part of the string for ease of use.

Client library

• Free memory used by OpenSSL in mosquitto_lib_cleanup() where possible.
• Change WebSocket subprotocol name to mqttv3.1 to make future changes easier and for compatibility with other implementations.
• mosquitto_loop_read() and mosquitto_loop_write() now handle errors themselves rather than having mosquitto_loop() handle their errors. This makes using them in a separate event loop more straightforward.
• Add mosquitto_loop_forever() / loop_forever() function call to make simple clients easier.
• Disable SSL compression. This reduces memory usage significantly and removes the possibility of CRIME type attacks.
• Enable SSL_MODE_RELEASE_BUFFERS mode to reduce SSL memory usage further.
• mosquitto_tls_set() will now return an error or raise an exception immediately if the CA certificate or client certificate/key cannot be accessed.
• Fix potential memory leaks on connection failures.
• Don't produce return error from mosquitto_loop() if a system call is interrupted. This prevents disconnects/reconnects in threaded mode and simplifies non-threaded client handling.
• Ignore SIGPIPE to prevent unnecessary client quits in threaded mode.
• Fix document error for mosquitto_message_retry_set().
• Fix mosquitto_topic_matches_sub() for subscriptions with + as the final character. Fixes bug #1085797.
• Rename all "obj" parameters to "userdata" for consistency with other libraries.
• Reset errno before network read/write to ensure EAGAIN isn't mistakenly returned.
• The message queue length is now tracked and used to determine the maximum number of packets to process at once. This removes the need for the max_packets parameter which is now unused.
• Fix incorrect error value in Python error_string() function. Fixes bug #1086777.
• Reset last message in/out timer in Python module when we send a PINGREQ. Fixes too-early disconnects.

Clients

• Clients now display their own version number and library version number in their help messages.
• Fix mosquitto_pub -l -q 2 disconnecting before all messages were transmitted.
• Fix potential out-of-bounds array access with client ids. Fixes bug #1083182.

Other

• mosquitto_passwd can now convert password files with plain text files to hashed versions.
