My CoreData stuff seems to be working fine in 10.4.3, but I'm just
wondering what data migration issues were fixed as CoreData doesn't
have any sort of data migration. Has Apple added some sort of data
schema migration? CoreData doesn't allow you to move data from one
schema to another which is a problem for if you update your schema.
At WWDC they made it sound like this was an issue they were looking
at addressing.
Or is this something different? Does data migration mean something
like moving from an XML store to a SQL store?

Can anyone clarify this?
The Core Data framework has been updated to improve relationship
management issues, resolve issues with data migration, improve Undo
and Redo commands, and improve insertion performance.
Specifically I'm wondering what the update means by resolving data
migration issues.

I too would be very interested in learning more about these
changes. It appears to fix an undo bug that I talked about in a
post to this list with the subject "CoreData 'Could Not Merge
Changes'". But since upgrading to 10.4.3 I'm having consistent
trouble with crashes after my app quits. I haven't tracked this
down yet, but it would be very nice to have some more detailed info
about what has changed.
