  - `[Code]` refers to internal changes to the code that have no direct impact on the web interface or the HTTP API, but are significant enough to warrant note.
  - `[Docs]` refers to changes to the [documentation](https://aq.connectedhumber.org/__nightdocs/00-Welcome.html).
 
+## v0.13.5
+ - Disable the tour, as it's now causing a crash on startup :-(
+ - [API] Don't return devices in the device lists that have the `visible` flag in the database set to `0`
+
+## v0.13.4
+ - [API] Fix crash in `list-devices-near` action
+
+
+## v0.13.3
+ - Update dependencies

 ## v0.13.2
  - Improve performance of device graph pop-up

+## Disclaimer
+This website displays sensor reading from devices created by individuals with an interest in monitoring their environment and is not endorsed or funded in any way by UK government supported bodies such as DEFRA. It is , however, hoped that this work may be useful in educational applications.
+
+The sensors, on the map, are installed in different ways, in different enclosures, at different heights and with different exposures to sunlight and wind . This means that, although individual sensors may use the same detectors, those detectors could produce varying results due to the above and also due to component tolerance spread. 
+
+No attempt has been made, by us, to calibrate the sensor readings in any way though the visual representation will include some aggregation of readings.
+
+If you wish to create a device to display data on this map please register with mattermost.connectedhumber.org and we will provide you with direction and designs to build your own sensor device.
