Actually, I think that's not an appropriate use of the announce list.

The average announce reader wants to know when a new release is out so
they go download it.

Understanding what this change even means requires an in-depth knowledge
of compilers and C++.

"Hi.  We're planning to change the default C++ ABI in the next version
of G++.  You won't notice because (a) you'll have to recompile
everything anyhow to use the library that comes with the new G++, and
(b) this only affects weird corner-cases.  However, if you happen to
have no weird corner-cases and are going to try to use the new compiler
with the old library, you might care.

So, do you object?"

I think that, given that the only people likely to notice are people who
are operating way outside the mainstream of C++ development, this is not
a decision that needs to be pre-announced.  It should of course go in
the release notes.
