Earlier today, Logitech introduced the MX Master 4 (curr. $119 on Amazon), a long-awaited successor to both the MX Master 3 and MX Master 3S in many regards. On top of that, the company has refreshed the older MX Master 3S in multiple markets after silently debuting a Bluetooth Edition earlier this year in North America.
As a pre-release leak suggested, the refresh brings the MX Master 3S Bluetooth Edition to regions like the Eurozone and the UK. As far as we can tell, Logitech has now discontinued the standard MX Master 3S in Europe and the UK after over three years of the wireless mouse being on sale. Conversely, the standard MX Master 3S is still available in North America at the time of writing.
In short, the Bluetooth Edition contains no hardware changes from the original MX Master 3S. Instead, Logitech has removed its Logi Bolt accessory that it includes with the standard MX Master 3S and the new MX Master 4. However, the MX Master 3S Bluetooth Edition retains Logi Bolt compatibility. Nonetheless, the Bluetooth Edition retails for £89.99, €99.99 and $99.99 for a healthy saving over the MX Master 3S' original MSRP. Please see Logitech's website for more details.
