16 Sep 2020 : Contrac 0.6.2 released #
I've just pushed the latest changes to github and made Contrac 0.6.2 available from OpenRepos. This update adds new Chinese translations and fixes a bug that prevented the update button from being used daily (a borked calculation meant you could only update every two days, or thereabouts).
14 Sep 2020 : Contrac 0.6.1 released #
After a busy weekend of work, Contrac 0.6.1 is now available from OpenRepos and with code on github. The latest improvements include Chinese translations (thanks to the sterling work of dashinfantry) a homescreen cover, attenuation value configuration, and risk configuration downloaded from the Corona-Warn-App servers to ensure the risk evaluations mirror the official app.
6 Sep 2020 : Contrac 0.5.1 released #
The latest version of Contrac now analyses the keys downloaded from the server against thoe collected using Bluetooth and provides an up-to-date risk assessment for the user. This is a pretty big step, because it means the app now has all the pieces needed to perform the full exposure notification cycle (diagnosis upload, key download, exposure analysis). There are still plenty of potential improvements of course, the main one being that it needs to be plugged in to the official severs rather than my test server, but hopefully that'll come soon. In the meantime, get it from OpenRepos and github.
1 Sep 2020 : Contrac 0.4.1 released #
Version 0.4.1 of Contac, an exposure notification app compatible with Germany's Covid-Warn-App is now available from OpenRepos and github. This latest version adds a bunch of improvements behind-the-scenes, including the encrypted metadata component of the BLE beacons and an improved data aggregation algorithm.
