-## Enter and exit criteria improvements for zones
-
-TODO:

-- Improve wording/flow a little
-- Pull down image locally, use standard image block
-- link justus502
-- Maybe move up a little?
-
-The enter and exit criteria for zones have been improved this release.
-
-So, location updates from device trackers have a center location and an accuracy.
-The true location of the device can be anywhere within the circle centered at
-location, with radius accuracy. Likewise, zones are circular defined by a center
-location and a radius.
-
-The previous criteria for zones would at every location update find the zone
-nearest to the center of the location update where the circles defined by the
-location update and the zone were overlapping, no matter how big the circle
-defined by the location update was.
-
-This meant it was possible to jump in to a very small zone based on a highly
-inaccurate location update.
-
-To illustrate further, @justus502 made an illustration:
-
-<img src="https://user-images.githubusercontent.com/14281572/115867224-165ab080-a43b-11eb-9deb-68d0763e321e.png" width="500" height="500">
-
-The brown circles are the GPS-coordinates in the center and the (in)accuracy
-sent by the device. The green circles are zones and their center in the middle.
-The red circle is the actual location of the device.
-
-The old logic would consider the device to be within all three zones
-(the green circles), and would pick the one to the upper left.
-
-As of this release it no longer enter a zone unless the location
-(the brown circle) is entirely within the green circle, this means none of the
-three zones in the illustration would be entered.
-
-Once a zone has been entered however, less accurate location updates
-(a larger brown circle) are allowed, and the zone won't be exited unless the
-location (brown circle) is no longer overlapping the zone (the green circle).
-
-TL;DR: This change will improve the zone a tracked device is in, is
-be less "jumpy" and will reduce false positives.
