- update from current 0.9.6-stable CHANGES file
- update from current 0.9.7-stable CHANGES file:

  Now here we have "CHANGES between 0.9.7e and 0.9.8", and I hope
  that all patches mentioned for 0.9.7d and 0.9.7e actually are
  in the CVS HEAD, i.e. what is to become 0.9.8.

  I have rewritten the 'openssl ca -create_serial' entry (0.9.8)
  so that it explains the earlier change that is now listed (0.9.7e).

  The ENGINE_set_default typo bug entry has been moved from 0.9.8
  to 0.9.7b, which is where it belongs.
