The version of the Variant library in the CVS' main trunk depends
(naturally) only on the main trunk components - MPL not being an
exception. The question is which parts of the main trunk you need/can
get without breaking things.

As far as MPL goes, I would say you can safely update it from the main
trunk - that is, if you are currently using 1.30.0 release.

To determine the status of other Variant dependencies you can use our
experimental status reports which employ automatically collected
1.30.0-snapshot's failures to highlight the differences between now and

Basically, 'unexp.' there signals a new failure (or a new library/test
case). Of course, you would have to use your own judgment to determine
how critical are those to you.
