should this say .7?                                ^

I'm not sure how much we usually list here but here's some stuff from
a look through the git log,

${(p.$param.)

some numerous changes to the vi mode, i don't use it but maybe oliver
can chime in?

waiting on already exited processes

whence -v lists file function was defined in
       -S shows intermediate symlink steps

$(< error not fatal anymore

faster history lockfile retrying

zsh/db/gdbm module, ztie -r / zuntie -u

pattern support in watch variable

aliasing && and other tokens (this is already in NEWS, but not listed
separately for .8)

posix builtins and exec + assignments

If you take the old-fashioned view that it should be correct, I suppose
so.

This all goes in NEWS rather than README; up to now I've assumed people
are more interested in comparing with 4.x releases, but that's unlikely
to be true any more --- so this and anything probably needs to go in a
new section at the top.

This should be POSIX_BUILTINS (the s being more important than the _,
but that would consistent with POSIX_ALIASES above).
