1.3.0

• Adds an optional portserver_address parameter to pick_unused_port() so that callers can specify their own regardless of os.environ.
• pick_unused_port() now raises NoFreePortFoundError when no available port could be found rather than spinning in a loop trying forever.
• Fall back to socket.AF_INET when socket.AF_UNIX support is not available to communicate with a portserver.

1.2.0

• Introduced add_reserved_port() and return_port() APIs to allow ports to be recycled and allow users to bring ports of their own.

1.1.1

• Changed default port range to 15000-24999 to avoid ephemeral ports.
• Portserver bugfix.

1.1.0

1.0.1

• Code reindented to use 4 space indents and run through YAPF for consistent style.
• Not packaged for release.

1.0.0
