 ### GBFS
 
-All MDS compatible `provider` APIs must expose a public [GBFS](https://github.com/NABSA/gbfs) feed as well. Given that GBFS hasn't fully [evolved to support dockless mobility](https://github.com/NABSA/gbfs/pull/92) yet, we follow the current guidelines in making bike information avaliable to the public.
+All MDS compatible `provider` APIs must expose a public [GBFS](https://github.com/NABSA/gbfs) feed as well. Compatibility with [GBFS 2.0](https://github.com/NABSA/gbfs/blob/v2.0/gbfs.md) or greater is advised due to privacy concerns and support for micromobility.
 
-* `gbfs.json` is always required and must contain a `feeds` property that lists all published feeds
-* `system_information.json` is always required
-* `free_bike_status.json` is required for MDS
-* `station_information.json` and `station_status.json` don't apply for MDS
+GBFS 2.0 includes some changes that may make it less useful for regulatory purposes (specifically, the automatic rotation of vehicle IDs). The [`/vehicles`](#vehicles) endpoint offers an alternative to GBFS that may more effectively meet the use cases of regulators. Additional information on MDS and GBFS can be found in this [guidance document](https://github.com/openmobilityfoundation/governance/blob/master/technical/GBFS_and_MDS.md).
