Linux 6.5 has many great features from the AMD P-State EPP driver default rather than ACPI CPUFreq for Zen 2 and newer supported AMD Ryzen systems, initial USB4 v2 enablement, initial MIDI 2.0 kernel driver work, more Intel hybrid CPU tuning, and a whole lot more.
I can't really blame the manufacturers because the USB-IF's suggested schemes would just confuse people even more. If people see 10Gbps on the box they're gonna assume it can do 10Gbps, but tons of stuff ends up capped well below the USB link speed (most everything based on SATA<->USB converters internally is 6Gbps max).
It's choosing between a bad naming scheme or something a lot of consumers would interpret as a straight up lie.
Yes it was never intended that any consumer hears about something like "USB 3.2 Gen 2" that was strictly internal naming for people developing USB devices.
The v2 part here really just refers to the fact that it's version 2 of the specification. Consumerrs only need to know the term USB4 and the speed that their device operates at. It's sort of like complaining that the ietf has terrible naming schemes because HTTP is defined in half a dozen RFCs with 4 digit numbers. This versioning is just meant for people developing USB things.
Actually this article here is one of the few times where even mentioning the version 2 part is reasonable since the details of these specifications actually matter to kernel developerrs. For everybody else it's just USB4 80 gbps.
yes these are the terms that are not supposed to be used in product naming or by consumers and are just intended for use by people developing USB devices.
