This is a new features release. Note that although the number of changes is relatively small, there is a fairly major change in the network socket handling (to allow >1024 clients) , which is one reason this has been treated as a separate release.

Changes:

• Use poll() instead of select() to allow >1024 clients.
• Implement max_connections.
• Run VACUUM on in-memory database on receiving SIGUSR2.
• mosquitto_pub can now send null (zero length) messages.
• Add option to print debug messages in pub and sub clients.
• hg revision is now exported via $SYS/broker/changeset
• Add compile time option to disable heap memory tracking.

Bug fixes:

• Don't store QoS=0 messages for disconnected clients with subscriptions of QoS>0.
• accept() all available sockets when new clients are connecting, rather than just one (performance advantage)
• Send Will when client exceeds keepalive timer and is disconnected.
• Check to see if a client has a will before sending it.
• Correctly deal with clients connecting with the same id multiple times.
• Fix bridge keepalive timeouts and reconnects.
• Don't attempt to drop root privileges when running on Windows as this isn't well supported (bug #586231).
