+> * I've finished the detailed security audit, and the fix for po4a
+> bugs has entered upstream CVS last week
+> * I've merged your new `checkcontent` hook with the `cansave` hook
+> I previously introduced in my own branch; blogspam plugin updated
+> accordingly
+> * the rename hook changes we discussed elsewhere are also part of my
+> branch
+> * I've introduced two new hooks (`canremove` and `canrename`), not
