Hi Folks,

LimeWire 4.2.4 is out. This is a service release in the 4.2 series which has some significant bugfixes. If you're running an earlier 4.2 version, you may want to consider upgrading. The free version is available from the LimeWire Download Page, and the pro is available on your personalized Pro page.

LimeWire 4.2.4 fixes the following:
- TCP ConnectBack requests now correctly establish a connection, allowing LimeWires to detect if they are firewalled. This change will require many people upgrading to the newer version in order to be useful.
- Various handshaking bugs are fixed. You can no longer maintain a connection between two leaves, and the first few connections attempts as a leaf will require a LimeWire Ultrapeer.
- Metadata wasn't being saved properly upon LimeWire's exit, causing LimeWire to rescan all shared files for metadata. With this fixed, LimeWire should use much less resources starting up and will share files with their metadata sooner.
- LimeWire would respond to multiple of the same push request if it received it from more than one location (push proxies or directly). This is corrected so that now LimeWire will only make one outgoing connection and discard the extra push messages.
- The method for LimeWire to distribute newer properties to the network was broken. This is now fixed. This will become effective when a large amount of users upgrade.
- If LimeWire attempted a firewall-to-firewall transfer and the other side was unable to request a file (but was able to connect), the connection would stall forever. This is now fixed to disconnect after an appropriate amount of time.
- Pongs that are from a UDP Host Cache can now have any ip address (even an invalid one) in the pong itself, so long as their is a valid DNS name of the UDP Host Cache in the pong.
- If someone attempted a Browse Host but did not indicate they can accept serialized gnutella messages, the response LimeWire gave was invalid. This is now corrected.
- The OSX installer is fixed to use the correct permissions (with much help from Roger Kapsi).

Thanks,
The LimeWire Team
