That is what we do. We pick up all the patches until the last minute, just
before starting the test. And as soon as we verify it is correct, we write and
send the pre-announcement email.

I think this depends on the authors, and how critical/urgent are those patches
that they can't wait for the next release (which happens every 2 weeks).

By default, nominated patches are queued for next release. If the release is the
last one, then it is never (bear in mind that as said in a different email,
17.3.7, is not the last one, and we need to update the calendar).

Exceptionally, people can request to include the nominated patch in the final
release if the problem it fixes is critical/urgent, that can't wait for the next
release. Likewise, if it is the last release I think it is fine for people to
request a new release more to include those changes.


All in all, I appreciate a lot your comments for improving the release process.
Actually there is a thread about this improvement. Pretty sure you can add also
comments there.

Thanks!
