 ## Upcoming release (under development)
+- add converter for `mds.bird.co` feed: remove `station_information`, `station_status` and `free_bike_status` feeds from gbfs.json if they are always empty.  
 
 ## 2024-06-14
 - add converter for `data.lime.bike` feed: remove `station_status` and `station_information` feeds from gbfs.json, as Lime associates all free floating bikes to a single station, which is semantically wrong.
