Let me say, straight off, that I think the ‘removal of copy-left’ code (or at least its replacement) has been done reasonably well. Potentially rather a confusing description though: there are still great big gobs of copy-left code as hard requirements for a useful Apache OpenOffice but these are category b copy-left, instead of the category x licenses: (including the LGPL) that Apache excludes. The functionality loss from this removal is modest, as new versions of dependencies have been selected or system dependencies added, with even some rule-bending around shipping GPL dictionaries.
On the other hand, thus far, there are rather few really new features in the release that did not come from Oracle’s existing work; that is outside of some pleasant drawing improvements, which we hope to merge into LibreOffice for our next major release.
