+* v0.7.1 — Markdown Rendering
+
+~render-styled~ accepts a ~(text . plist)~ segment list from the span
+parser and emits ~draw-text~ calls. The ~w~ parameter is ignored (layout
+is line-at-a-time, not fixed-width); ~theme-color~ is fully qualified
+as ~passepartout.channel-tui:theme-color~ since this function lives in
+the ~passepartout~ package but the theme API is in ~passepartout.channel-tui~.
+
+The inline span parser (~parse-markdown-spans~) delegates punctuation
+delimiters (**bold**, `code`, *italic*) to a local ~pick~ helper.
+URLs are handled directly via ~url-end~ rather than through ~pick~,
+so the ~:url~ clause was removed from ~pick~'s ~case~ form to avoid
+dead code.
