Looks very good. I took a look and this is what I saw:

The sgf handling has been reimplemented. The earlier gnugo.el-2.2.8
had problems with sgf files that I don't see any more. With 2.2.10
there are longer problems saving a file, reloading it, playing on,
then saving it again.

And the sgf files that are written seem fully compliant with
the sgf specification. Sgfc (which is the reference sgf
parser) found them OK. Previously, the requirement that
an sgf node could not have repeated properties was violated
by gnugo.el-2.2.8, regarding the AB and AW properties.

This is the main user-visible improvement but the
behind-the-scenes rewriting should make this version
more hackable in preparation for adding features.
