What is ST-Link V3E - difference from V3EC?

[JSK]

When I saw the version of ST-Link on the Nucleo board, I saw that there is V3E of V3 and there is V3EC, but if you look at the data sheet of ST-Link, there is only an explanation of the EC version, but there is no explanation of E. Is there any support for this?

EDIT:

Sorry, misread the OP: Indeed, V3E is mentioned many times in that TN1235 - but it is never explained.

There is nothing that describes what differs between V3E and V3EC

Thanks for the reply, I saw the edit  Looking at the Nucleo descriptions, there is a mention of E but no explanation, so I wrote a post.
