This release changes how Dawarich handles a city visit threshold. Previously, the `MINIMUM_POINTS_IN_CITY` environment variable was used to determine the minimum *number of points* in a city to consider it as visited. Now, the `MIN_MINUTES_SPENT_IN_CITY` environment variable is used to determine the minimum *minutes* between two points to consider them as visited the same city.
The logic behind this is the following: if you have a lot of points in a city, it doesn't mean you've spent a lot of time there, especially if your OwnTracks app was in "Move" mode. So, it's better to consider the time spent in a city rather than the number of points.
In your docker-compose.yml file, you need to replace the `MINIMUM_POINTS_IN_CITY` environment variable with `MIN_MINUTES_SPENT_IN_CITY`. The default value is `60`, in minutes.
