This new version contains a number bug fixes and some security fixes.
Fuzzy testing surfaced methods to crash GnuGk remotely, causing at least a denial of service. So all users are encouraged to update.
The most notable new feature are probably the events for Setup messages on the status port so now you can see all calls. In addition, LuaAuth has been given access to more information about received messages and can end your status port sessions with Ctrl-C now.
Important bug fixes are in the H.460 NAT traversal code where sometimes keep-alive intervals could be too long in older versions and a bug where GnuGk might have missed port re-negotiations in some cases.
The IgnoreSignaledIPs port detection code also has a few bug fixes to detect cases where it should be turned off automatically because its either not needed because the parties use another form of NAT traversal or non-symmetric ports where the detection algorithm may cause more harm than good.
