Towards the end of the upcoming week, I am going to release new version with updated Valhalla lib. This is going to be synced with the distribution of the maps, as Valhalla 3.x is incompatible with Valhalla 2.x which is used by you now. At least for now, public transport data is not imported into Valhalla database, I will have to look if its possible now.

So, while I have been testing it for 10 days and going to test a bit more, there is a possibility that something will go wrong. If you have upcoming trip and prefer not to risk, download your maps in advance. I will notify when the map update process will start
