...so this is why I typically leave the language as is. There are a
bunch of more correct permutations for how to describe what to do that
it's just simpler to say "will need to use..."

And because it's for betas/rc, the typical profile of one adopting the
betas are typically either developing the software or are very
experienced users. For those who are kicking the tires, the message
provides the safest of all options.

Now, if this were an update release, and if for whatever we had included
a catversion bump in the update release, I'd certainly mention that
explicitly.

My inclination is to leave the statement alone or use that 2nd proposal
I listed upthread.
