OmniGraffle 5.1 beta 4 is now available

And another beta release is made, this time concerned with fixing a number of Visio import problems as well as addressing some rendering issues with objects on shared layers, among other things.

Of particular note is that we've gone back to a single thread for text layout, we're hoping that this will address the problems some users have been running into with individual characters going missing at certain zoom levels, so if you have been running into this, you'll want to check out beta 4.

As always, the beta download page and release notes await.
