The changes since Phex 3.4.0 are:

• Less wait time for the first connections,
• Strong leafs become Ultrapeers,
• Automatic reconnect on network failure.

And a few squashed bugs.

But even though Phex made good progress, we want it to evolve even faster, and so we're searching for additional developers who want to join us in development.

If you want to contribute to Phex, please come into our forums or meet us in IRC via #phex @ freenode.net.

- CORE: In case Phex appears to be offline it will attempt to reconnect every
        two minutes.

- FIXED: Problems with large files.
