v7.3.0

This release adds setting the group id (GID) of wag control socket so that control can be a low priv to higher priv operation. Additionally it adds the ability to reuse registration tokens for a bounded number of times as per #50.

Bug Fixes:

• Restrict DNS servers to 53/any rather than any/any as per #49

Features:

• The cli option registration now takes an additional -uses option which enables a token to be used multiple times (default 1)
• Web user interface registration token dialog has similar options
