Overview

There has been no roadmap published by the DTA. We sometimes hear through the media that an update may be coming, but we don't know what that update will contain until it is published, and then it is just the brief release notes on the app stores or we compare the decompiled app with the previous version. The only certain item that has been mentioned several times is that they are planning to integrate the Exposure Notification APIs developed by Apple and Google. But there has been no mention or discussion by the DTA on what this integration may involve.

Original Twitter thread

If the @DTA were to update the #COVIDSafe app with the Google/Apple Exposure Notification APIs, it would require some hefty changes to a lot of things. A brief investigation.

"How did the Covidsafe app go from being vital to almost irrelevant?"

Vanessa Teague quoted as saying the adoption of the Exposure Notification APIs would require large changes to the operation of the app, and that it would require people to run both apps (the current app and a separate app using the Exposure Notification APIs) for a few weeks.
