[richfab]

📣 Your weekly GBFS news update! 🚲 🛴 🛵 🚘

👀 This month, to let everyone know which GBFS feeds support a given version of GBFS, we plan to add in systems.csv the GBFS versions supported by each feed (#659).

✨ Producers of GBFS v3.0, please send us your v3.0 URLs. We’ll update systems.csv to give everyone access to the latest version. Thank you!

🌞 Lastly, it's as impressive to see 4 bikeshare services in the same photo as it is to see sunny London! Thank you @carlfredl for this photo.

👋 See you next week!
