From Apache OpenOffice Wiki
It's good to warn users that there are traps in 3.x, but it would be better to tell them exactly what those traps are. Chief among them (and a dealbreaker, in my opinion), is the insertion of unwanted page breaks before subdocuments. OO 2.4.1 did not have this bug, and there is no really good workaround for it. This bug renders the master document feature almost useless, as every subdocument starts on a new page whether the user wants it to or not. Until this bug is fixed, users should be warned that master documents in 3.x will not behave as they did in 2.4.1, and it might be preferable for users to continue using 2.4.1.
