++ The new user option ~logos-hide-fringe~ conceals the fringe by
+  applying the same background as the default face.  It does not
+  interfere with ~fringe-mode~, such as by adjusting its size.  This
+  option complements ~logos-olivetti~ and is only relevant if the
+  ~fringe~ face has a distinct background.
+
++ The new ~logos-focus-mode-extra-functions~ is an ordinary hook that
+  unlocks the potential of ~logos-focus-mode~ by allowing the user to
+  trigger any effect when the mode is toggled.  Its doc string
+  references functions from =logos.el= that can be adapted at the user
+  level to pursue varied ends, while the manual furnishes a ready-to-use
+  sample for ~org-indent-mode~.  This feature was inspired by the
+  inquiry of Ypot in issue 1 over at the GitHub mirror:
+  <https://github.com/protesilaos/logos/issues/1>.
+
++ The default value of the user option ~logos-outline-regexp-alist~ now
+  includes an entry for ~markdown-mode~ to determine what constitutes a
+  heading there.  This helps with motions such as
+  ~logos-forward-page-dwim~ while it makes Markdown equally useful for a
+  focused reading or presentation (with ~logos-focus-mode~).
+
++ The manual includes a link to a publication of mine where I explain
+  what the "devel" version of GNU ELPA is and how to make use of it:
+  <https://protesilaos.com/codelog/2022-05-13-emacs-elpa-devel/>.
