Hi, Andrew!

Thanks for your reply!  I have just a few more questions below.

BTW, the quoting is messed up for the text/plain part of your email:
none of the quoted text is prefixed with a greater-than sign ('>') or
other marking string.  I've fixed it in this reply.

I understood that the major version number jumped from 3 to 7 (because 3
+ 4 = 7), but I didn't know about a name change.  This is probably where
I'm confused.

What is the name of the 7.0 release series?  I thought it was "EPICS
Base 7.0".

What is the name of the 3.15 release series?  I thought it was "EPICS
Base 3.15".

What is being listed in that list?  I thought it was basically "Release
[series] X.Y" where the word "series" is implied and omitted.  I thought
the list labeling was leaving out the "EPICS Base" part of the name and
just saying it's "Release [series] X.Y".  If all of that is true (which
it's probably not), then I was suggesting that the 7.0 release series
name of "EPICS Base 7.0" would translate to "Release 7.0" which would
match the existing pattern of "Release [series] X.Y".

Regards,

Lewis
