+
+- NEW FEATURE: rem2pdf: Add a command-line option to make the calendar title
+  into a hotlink to a URL that you supply.
+
+- IMPROVEMENT: remind: Make the tzconvert() function warn about possibly
+  invalid time zone names, similar to the warning issued by the TZ keyword.

+- IMPROVEMENT: "make test": If spellintian and hunspell are installed,
+  use them to spell-check and lint the man pages and README.md file.

+
+- MINOR FIXES: Fix various spelling errors caught by hunspell.
+

+
+- MINOR BUG FIX: remind: Suppress spurious debugging output when using
+  "-dt" flag with a TZ clause.
+
+- MINOR BUG FIX: remind: For the purposes of purge mode, don't consider a
+  non-constant expression in the *body* of a reminder to be a problem.
+

+  leaks.
+
