This is a bugfix and security release.
# Version 1.5.5 changes
## Security
- If `per_listener_settings` is set to true, then the `acl_file` setting was
ignored for the "default listener" only. This has been fixed. This does not
affect any listeners defined with the `listener` option. Closes [#1073].
## Broker
- Add `socket_domain` option to allow listeners to disable IPv6 support.
This is required to work around a problem in libwebsockets that means
sockets only listen on IPv6 by default if IPv6 support is compiled in.
Closes [#1004].
- When using ADNS, don't ask for all network protocols when connecting,
because this can lead to confusing "Protocol not supported" errors if the
network is down. Closes [#1062].
- Fix outgoing retained messages not being sent by bridges on initial
connection. Closes [#1040].
- Don't reload `auth_opt_` options on reload, to match the behaviour of the
other plugin options. Closes [#1068].
- Print message on error when installing/uninstalling as a Windows service.
- All non-error connect/disconnect messages are controlled by the
`connection_messages` option. Closes [#772]. Closes [#613]. Closes [#537].
## Library
- Fix reconnect delay backoff behaviour. Closes [#1027].
- Don't call `on_disconnect()` twice if keepalive tests fail. Closes [#1067].
## Client
- Always print leading zeros in `mosquitto_sub` when output format is hex.
Closes [#1066].
## Build
- Fix building where TLS-PSK is not available. Closes [#68].
