Let's just say that during the -rc freeze period, because I can stop
looking at or queuing completely new topics to encourage people who
are responsible for topics in the upcoming release to focus more on
responding to regressions and follow-up fixes necessary, I have a
better chance of having some leftover time to look into things
myself, at least enough to figure out what needs to be done, ;-)

Maybe, maybe not. I'll decide after adding the bundle_version field
to the structure (which will be read from an existing bundle, but
which will have to be set for a bundle being created).
Thanks.
