The latest news is that they are working with Hackerone to test the website and app before going live. Richard Ells mentioned this would take 3-4 weeks. At this time there is about 3 weeks left of the 4.
According to Electroneum's Facebook page, Hackerone has started testing on Monday 13 November 2017 and will submit a security report to the team in due time.
Apart from that, nothing much has happened yet. No additional exchanges. However, there has been a surge in business (offline and online) that have advertised that they are now accepting ETN as payment.
