I have a few devices (a Core and three Photons). Others are offline, but Photon #2 is still on 0.6.0, while #3 is on 0.61 now. That said, build.particle.io says of the latter: “On the device: 0.6.0” (likewise in the new “status bar” area below the code window).
Reloaded the page and reloaded the device page and even re-flashed the code I’m working on - no change. Signal works - I’m definitely looking at the right device, and it is starred. Verified via setup mode that 0.6.1 is on the device/
So, it’s a possible bug in build.particle.io - either it’s just wrong or it’s parsing a different device when it should be showing info specific to the selected target device.
