+------------
+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.
+
+-----------------
+OBSOLETE FEATURES
+-----------------
+
+- The undocumented -queue switch to post was deprecated in nmh 1.6, and was
+ removed in this release.

+ removed from a future nmh release. Instead, use the -debug switch to pick.
+
+---------
+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.
