Proposing 10.5.0 minor release

Hi everyone,

It=E2=80=99s been a few months now since the 10.4 release, and we have =
some impressive changes building up on the 10x branch.  I think it=E2=80=99=
s about time we did a new minor?

I=E2=80=99m happy to act as RM, unless somebody else is desperate to do =
it. I would plan on starting the release process this time next week.  =
If there=E2=80=99s in-flight work that you really need to get into 10.5, =
now would be a good time to open a PR :)

Thanks, Alan=
