+  ### Changes
+
+  - Improve formatting of doc-comments (#2338, #2349, #2376, #2377, #2379, #2378, @Julow)
+    Remove unnecessary escaping and preserve empty lines.
+  - \* Indent `as`-patterns that have parentheses (#2359, @Julow)
+  - Don't print warnings related to odoc code-blocks when '--quiet' is set (#2336, #2373, @gpetiot, @Julow)
+  - \* Improve formatting of module arguments (#2322, @Julow)
+  - \* Don't indent attributes after a let/val/external (#2317, @Julow)
+  - Consistent indentation of `@@ let+ x = ...` (#2315, #2396, @Julow)
+    It was formatted differently than `@@ let x = ...`.
+  - \* Improve formatting of class expressions and signatures (#2301, #2328, #2387, @gpetiot, @Julow)

+  - \* Improve indentation of `~label:(fun ...` (#2271, #2291, #2293, #2298, #2398, @Julow)
+    The `fun` keyword is docked where possible and the arguments are indented to avoid confusion with the body.
+  - JaneStreet profile: treat comments as doc-comments (#2261, #2344, #2354, #2365, #2392, @gpetiot, @Julow)
+  - Tweaks the JaneStreet profile to be more consistent with ocp-indent (#2214, #2281, #2284, #2289, #2299, #2302, #2309, #2310, #2311, #2313, #2316, #2362, #2363, @gpetiot, @Julow)
+---
