+NEW FEATURES
+------------
+
+- builds use OpenSSL if available.
+- post now defaults to port 587 on 'smtp' message submission.
+- A value of 0 for the width switch of scan(1), inc(1), ap(1), dp(1),
+ fmttest(1), and mhl(1) now means as many characters as the format
+ engine can produce [Bug #15274]. That amount is limited by internal
+ buffers.
+- If a component has trailing whitespace, e.g., body:component="> ",
+ mhl now trims that whitespace off when filtering blank text lines.
+- An "rtrim" flag has been added to mhl to remove any trailing
+ whitespace from filtered text lines. A corresponding "nortrim" flag
+ has also been added.
+- The default locations for configuration files and suppoooort binaries
+ have been changed. Configuration files now install into ${sysconfdir}/nmh,
+ and support binaries are placed in ${libexecdir}/nmh. If you are upgrading
+ an existing installation you should look for old configuration files in
+ ${sysconfdir} and merge any local customizations into the new files in
+ ${sysconfdir}/nmh, then remove the old files. ${libdir} will also contain
+ obsolete support programs that should be removed.
+- When building from source, configure will derive ${prefix} from an existing
+ nmh installation if it finds one in your $PATH.
+- Added getmymbox and getmyaddr mh-format(5) function escapes.
+- New -changecur, -nochangecur, and -fixtype switches have been added
+ to mhfixmsg(1).
+- mhfixmsg now removes an extraneous trailing semicolon from header
+ parameter lists.
+- added multiply format function
+- "mhparam bindir" prints the path to the directory containing the public
+ executables (${bindir}).
+- new "-prefer" switch for mhshow (and mhlist and mhshow), to allow specifying
+ the preferred content types to show, if present in a multipart alternative.
+- mh-format now has %(kilo) and %(kibi) functions, to allow printing
+ numbers as, for example, "10K", or "2.3Mi"
+
+-----------------
+OBSOLETE FEATURES
+-----------------
+
+- The undocumented -queue switch to post was deprecated in nmh 1.6, and was
+ removed in this release.
+- conflict(8) was deprecated in nmh 1.6, and was removed in this release.
+- mhtest(8) was deprecated in nmh 1.6, and was removed in this release.
+- msh(1) was deprecated in nmh 1.6, and was removed in this release.
+- Support in alias files for the the "*" address-group (everyone) was
+ deprecated in nmh 1.6, and was removed in this release.
+
+-------------------
+DEPRECATED FEATURES
+-------------------
+
+- Support for the MHPDEBUG environment variable is deprecated and will be
+ removed from a future nmh release. Instead, use the -debug switch to pick.
+- With the move of support binaries from ${libdir} to ${libexecdir}/nmh, the
+ mostly undocumented 'libdir' mhparam(1) component has been replaced by a
+ new 'libexecdir' component. 'libdir' will be removed in a future release.
+
+---------
+BUG FIXES
+---------
+
+- The format scanner no longer subtracts 1 from the width. This has the
+ effect of no longer counting the trailing newline in the output of
+ scan(1), inc(1), and the other programs that rely on the format scanner.
