There are currently some known issues in the release:

• integration with other reitti instances needs work
• sharing data with other users is untested
• preferred colored map has no effect
• label translations in the frontend need an overhaul
• I dropped the default photon instance, which needs documentation how the migration is done
• our new Geocoder Paikka has an issue determing the boundaries of a place (working on it)
• custom tiles server needs manual migration since we switched the technology and now are relying on a style.json to format the vector data. But I am hosting a free to use tiles server for all now. ( and the free to use reverse geocoder)

And propably some unknown:

• imports are not tested
• data ingestion is not tested
• preview function for visit sensitivity is not tested
