This post basically just points at a new YouTube video from Nerdabetic at the bottom of this post. The quote below is from the video description.

> Medtronics newest CGM is here and it has just been CE marked **for Europe and Middle Eastern countries**. Guardian 4 is Medtronics first calibration-free CGM (finally) and it will be rolled out across Europe in coming months. Guardian 4 works with Medtronic 780G, a newly approved Inpen smart pen from Companion Medical or Guardian standalone CGM.

One interesting comment from the video was that the formal testing rates G4 as _less_ accurate than the previous G3. Ah, well, baby steps then. 🤔

The more interesting Medtronic CGM is still in development. Code named Project Synergy, Nerdabetic expects it will eventually be released as Guardian 5. It appears it will be a combed sensor & transmitter with a form factor resembling the Dexcom G7.
