[Box-Admins] Planned update to squeaksource.com on dan.box.squeak.org

[David T. Lewis]

Our current squeaksource.com image is running on an older Squeak version,
and its SqueakSource packages are out of date with respect to the
source.squeak.org server.

I had looked into doing a squeaksource.com update a couple of years ago,
but at that time I was not able to complete it due to some issues with
ReferenceStream serialization, which is required for exporting the SS
repository and importing it into an new image.

The earlier issues with ReferenceStream serialization are resolved in
Squeak 5.3, so it is now possible to export the serialized respository
from the old image and import it into a Squeak 5.3 image.

I have prepared a Squeak 5.3 based image for squeaksource.com, and I'd
like to try swapping it into service some time soon. This will be a quick
switchover (about one minute or less), and in the event of problems the
rollback to the prior version will happen within a few minutes.

However, the actual process of exporting the repository and importing it
to the new image takes about six hours on my PC, so the overall conversion
will take quite a while for me to do, and I will need to pick a day when
I have some free time before I do it.

This is just a heads-up that I have the new image prepared, and am planning
to deploy it some time in the coming days or weeks. I will send email to
squeak-dev prior to actually flipping the switch.
