Release v3.9.4

We were sending the trackId as intent extra (actually unused) and this trackId could not be unparceled.
Fixes #411.

+# How to contribute?
+
+## Testing 
+
+Just use OpenTracks and tell us what can be improved by opening an issue [here](https://github.com/OpenTracksApp/OpenTracks/issues/new/choose)
+
+If we broke things (happens now and then), please tell us also.
+
+## Coding new features
+
+You have a cool idea for a feature that is missing in OpenTracks?
+And you would like to help by implementing it?
+If not, you can just take a look at the [issue tracker](https://github.com/OpenTracksApp/OpenTracks/issues).
+
+Advices:
+* creating an issue beforehand might be a good idea
+  Sometimes it is helpful to discuss your idea and also your implementation approach first.
+  We may be able to give you some hints on how to tackle the problem.
+  It also makes merging your changes easier and, usually, faster.
+* please only add new dependencies if is absolutely necessary
+  If you need to:
+  * tell us why those are required,
+  * what alternatives are existing, and
+  * why you choose this dependency.
+  And also verify that the license(s) are compatible with _Apache 2.0_ as well as open-source.
+ 
+## Coding conventions
+
+None so far.
+Just keep it simple.
+And follow the _scout rule_. 
+
+You can take a look at existing code and get a feeling for it.
+
+Please autoformat your code using AndroidStudio's code formatter.

-_Please note:_
-_Tracks_ does not contain a _map_ (as this would required Internet access).
-To show your tracks on a map, a 3rd party application (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand) or [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro)) needs to be installed.  
+An overview of Bluetooth LE sensors that are known to work with OpenTracks is in [README_TESTED_SENSORS.md](README_TESTED_SENSORS.md).
 
-## Custom Dashboards
+_Please note:_
+_OpenTracks_ does not contain a _map_ (as this would required Internet access).
+
+## Custom Dashboards (incl. Map)
 As of v3.3.1 OpenTracks enables to use custom dashboards.
 The reference implementation is [OSMDashboard](https://github.com/OpenTracksApp/OSMDashboard), which presents an OpenStreetMap map (showing the current track, incl. updates).
+The developer documentation is in [README_API.md](README_API.md).
+
+Alternatively, recorded tracks can be shared as KMZ/GPX to installed applications (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand) or [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro)).
+However, this is rather slow and does not provide updates while recording.

 This include limited configurability (e.g., ordering of shown elements) and the lack of Internet access.
 In fact, the later is considered a feature but severely limits the implementation presenting a map (at least in an easy way). 
 
-_NOTE:_ for showing a track on a map a workaround was implemented in OpenTracks.
-Data could be exported as KMZ and presented in 3rd-party application (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand) or [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro)).

 For the time being, the OpenTracks Data API can be used to implement mainly custom dashboards.
 
 ## Implementation
 OpenTracks by default does not expose any data to 3rd-party applications.
-On the request of the user (i.e., pressing a button), an Intent is created that exposes the `Track` data (it's summary) as well as the `TrackPoint`s of one or more selected tracks.
+On the request of the user (i.e., pressing a button), an Intent is created that exposes the `Track` data (it's summary), the `TrackPoint`s, and the `Waypoint`s of one or more selected tracks.
 For each, one URI is provided.
 These URIs notify observers if on content changes (e.g., a new `TrackPoint` was added).
