Appendix B. What's New Since V8.8
Many things have changed since the
release of the second edition of this book. That edition covered
sendmail through V8.8. Since then, V8.9 through
V8.12 have been released.
Unfortunately, there is no completely satisfactory way to indicate
all those changes within the text proper of this book. Instead, we
have elected to list the changes in this appendix, ordered by the
chapter in which they are described, and thus, essentially by
subject.
Note that in addition to describing new sendmail
versions, this edition of the book also offers three new chapters
that cover performance tuning, spam handling, and
sendmail's companion programs.
Also note that this appendix is not the final
authority about new items in sendmail. Instead,
you should read the RELEASE_NOTES file supplied with the source
distribution.
