There seems to be a crash on 2.5 that happens like this…
OmniFocus 2.1.1 is happy.
You use a share sheet from some other app to send something to OmniFocus.
That 2.1.1 item is sitting, waiting for OmniFocus.
You update to OmniFocus 2.5.
You launch the shiny new OmniFocus 2.5.
It tries to open the 2.1.1-style item and gets confused.
So, to prevent this, launch OmniFocus 2.1.1 one last time to import any items you might have shared before updating to 2.5.
OR if any of you are crashing on launch in 2.5 and think this might be why, please let us know if you’d be willing to try out a Test Flight build.
