AFAIU ZODB3 was a distribution that contained the following importable
Python packages:
BTrees
ZEO
ZODB
persistent
These are now packaged as individual distributions ("eggs"), with the
ZODB3 egg acting as a transitional package that pulls them all in, so
that apps that used to depend on ZODB3 would continue to work.
