Topo Maps 2 has now been released, and the beta test is closed.
If you have a beta version of the app installed it will continue to function for about 90 days, and then probably fail to start without warning.
If you now install Topo Maps 2 from the App Store I believe that the public version will replace the beta, importing the maps, waypoints, tracks etc. from your beta version. I can't be certain about that so beware. You will need to agree to a paid subscription in order to view your downloaded maps.
Many thanks to everyone who sent feedback during the beta (you know who you are!). Do please continue to send me your comments, suggestions, bug reports etc. Version 2.1 won't be too far in the future!
