+- **Added:**
+  the notation :g:`term%_scope` to set a scope only temporarily
+  (in addition to :g:`term%scope` for opening a
+  scope applying to all subterms)
+  (`#14928 <https://github.com/coq/coq/pull/14928>`_,
+  fixes `#11486 <https://github.com/coq/coq/issues/11486>`_
+  and `#12157 <https://github.com/coq/coq/issues/12157>`_
+  and `#14305 <https://github.com/coq/coq/issues/14305>`_,
+  by Hugo Herbelin, reviewed by Pierre Roux).
+- **Removed**
+  the ability to declare scopes whose name starts with `_`
+  (would be ambiguous with the new :g:`%_scope` notation)
+  (`#14928 <https://github.com/coq/coq/pull/14928>`_,
+  by Pierre Roux, reviewed by Hugo Herbelin).
+- **Deprecated**
+  the notation :n:`term%scope` in :cmd:`Arguments` command.
+  In a few version, we'll make it an error and in next version give it
+  the same semantics as in terms (i.e., deep scope opening for all
+  subterms rather than just temporary opening)
+  (`#14928 <https://github.com/coq/coq/pull/14928>`_,
+  fixes `#11486 <https://github.com/coq/coq/issues/11486>`_
