The following news release is from MyHeritage:
For the past 2.5 years, MyHeritage and FamilySearch engineers have been developing together a unique feature — FamilySearch Tree Sync — that allows members of the Church of Jesus Christ of Latter-day Saints (LDS) to easily and accurately import a portion of their tree from FamilySearch into MyHeritage, and then keep their MyHeritage and FamilySearch trees synchronized. This feature is now released in a limited beta, and volunteers who are LDS members are invited to try it out.
Please see more info about joining the beta, and this feature, in the blog post here:
