I will later today be doing an upgrade to the software that runs the
wiki for the GRAMPS website.
I've tested the upgrade process and am confident all will go well. I
will, however, need to stop access to the wiki for a short period of
time, to make sure that I get an accurate 'snapshot' of the database
should we need to rollback to that.
I'll send another posting to both gramps-devel and gramps-users just
before taking it down, and again when I've got it back.
