This announcement summarises the changes in both 0.5 and 0.5.1.
|
||
|
|
|
||
|
|
The interesting changes:
|
||
|
|
|
||
|
|
* Add mosquitto_sub and mosquitto_pub, simple clients for subscribe/publish.
|
||
|
|
* Change persistence behaviour. The database is now stored in memory even if
|
||
|
|
persistence is enabled. It is written to disk when mosquitto exits and also
|
||
|
|
at periodic intervals as defined by the new `autosave_interval` option. This
|
||
|
|
makes persistence more suitable when being used on devices with a limited
|
||
|
|
number of writes, such as flash.
|
||
|
|
* Default sqlite3-pcre path on Linux is now /usr/lib/sqlite3/pcre.so to match
|
||
|
|
new sqlite3-pcre packages.
|
||
|
|
|
||
|
|
The less interesting/bug fixes:
|
||
|
|
|
||
|
|
* No longer store QoS=0 messages for disconnected clients that do not have
|
||
|
|
clean start set.
|
||
|
|
* Rename `msg_timeout` option to `retry_interval` for better rsmb
|
||
|
|
compatibility.
|
||
|
|
* The writing of the persistence database may be forced by sending mosquitto
|
||
|
|
the SIGUSR1 signal.
|
||
|
|
* Clients that do not send CONNECT as their first command are now
|
||
|
|
disconnected.
|
||
|
|
* Boolean configuration values may now be specified with true/false as well as
|
||
|
|
1/0.
|
||
|
|
* Log message on CONNECT with invalid protocol or protocol version.
|
||
|
|
* Add man pages for clients.
|
||
|
|
* Add general man page on mqtt.
|
||
|
|
* Root privileges are now dropped only after attempting to write a pid file
|
||
|
|
(if configured). This means that the pid file can be written to /var/run/
|
||
|
|
directly and should fix bug #523183.
