On the Wikipedia page about Mishkan T’filah, I found this:
A World Union for Progressive Judaism edition of Mishkan T’filah is being developed that will reflect the more traditional approach often taken by English speaking Progressive Jewish communities outside the United States of America. This edition of Mishkan T’filah will also be sensitive to the experience of Jews living in the Southern Hemisphere (particularly Australia, New Zealand and South Africa) where traditional liturgical seasonal references relating to the Land of Israel are out of step with local weather cycles.
Anyone know anything about this notion? Any attribution? Anything?
