-- Minimum Werkzeug version bumped to 0.14, but please use the latest
-  version.
-- Minimum Click version bumped to 4, but please use the latest version.
+- Bump minimum dependency versions to the latest stable versions:
+  Werkzeug >= 0.14, Jinja >= 2.10, itsdangerous >= 0.24, Click >= 5.1.
+  (`#2586`_)
 - Make ``app.run()`` into a noop if a Flask application is run from the
   development server on the command line. This avoids some behavior that
   was confusing to debug for newcomers.
