1.6.3 - 20190618
================
Broker:
- Fix detection of incoming v3.1/v3.1.1 bridges. Closes #1263.
- Fix default max_topic_alias listener config not being copied to the in-use
listener when compiled without TLS support.
- Fix random number generation if compiling using `WITH_TLS=no` and on Linux
with glibc >= 2.25. Without this fix, no random numbers would be generated
for e.g. on broker client id generation, and so clients connecting expecting
this feature would be unable to connect.
- Fix compilation problem related to `getrandom()` on non-glibc systems.
- Fix Will message for a persistent client incorrectly being sent when the
client reconnects after a clean disconnect. Closes #1273.
- Fix Will message for a persistent client not being sent on disconnect.
Closes #1273.
- Improve documentation around the upgrading of persistence files. Closes
#1276.
- Add 'extern "C"' on mosquitto_broker.h and mosquitto_plugin.h for C++ plugin
writing. Closes #1290.
- Fix persistent Websockets clients not receiving messages after they
reconnect, having sent DISCONNECT on a previous session. Closes #1227.
- Disable TLS renegotiation. Client initiated renegotiation is considered to
be a potential attack vector against servers. Closes #1257.
- Fix incorrect shared subscription topic '$shared'.
- Fix zero length client ids being rejected for MQTT v5 clients with clean
start set to true.
- Fix MQTT v5 overlapping subscription behaviour. Clients now receive message
from all matching subscriptions rather than the first one encountered, which
ensures the maximum QoS requirement is met.
- Fix incoming/outgoing quota problems for QoS>0.
- Remove obsolete `store_clean_interval` from documentation.
- Fix v4 authentication plugin never calling psk_key_get.
Client library:
- Fix typo causing build error on Windows when building without TLS support.
Closes #1264.
Clients:
- Fix -L url parsing when `/topic` part is missing.
- Stop some error messages being printed even when `--quiet` was used.
Closes #1284.
- Fix mosquitto_pub exiting with error code 0 when an error occurred.
Closes #1285.
- Fix mosquitto_pub not using the `-c` option. Closes #1273.
- Fix MQTT v5 clients not being able to specify a password without a username.
Closes #1274.
- Fix `mosquitto_pub -l` not handling network failures. Closes #1152.
- Fix `mosquitto_pub -l` not handling zero length input. Closes #1302.
- Fix double free on exit in mosquitto_pub. Closes #1280.
Documentation:
- Remove references to Python binding and C++ wrapper in libmosquitto man
page. Closes #1266.
Build:
- CLIENT_LDFLAGS now uses LDFLAGS. Closes #1294.
