Hi everyone,

Quick question:

It's my reading of RFC 8276 and RFC 8178 that 8276 (user extended attributes) extends the (then) current minor version - 4.2. So 4.1 or 4.0 servers/clients can not use this functionality.

Is that correct? The wording doesn't seem to be that clear,  but I might have missed something, so hence my question.

This came up because there's no technical issue with implementing 8276 on top of 4.1 or even 4.0. But my reading is that this would violate the RFCs.

Thanks,

- Frank
