+** The =library-unloaded event now includes the 'ranges' field, which
+ has the same meaning as for the =library-loaded event.
+
+** The =library-unloaded event now includes the 'still-in-use' field.
+ This field is 'true' when a library is unloaded (removed from the
+ inferior's list of loaded libraries), but the mapping within the
+ inferior's address space is retained, as the library was mapped
+ multiple times, and the same mapping was being reused. In all
+ other cases, this field will have the value 'false'.

@item =library-unloaded,...
Reports that a library was unloaded by the program. This notification
-has 3 fields---@var{id}, @var{target-name} and @var{host-name} with
-the same meaning as for the @code{=library-loaded} notification.
+has the following fields---@var{id}, @var{target-name},

+@code{=library-loaded} notification.
+
+It is possible that a library can appear multiple times in an
+inferior's library list, but the library is only mapped once into the
+inferior's address space. When this happens, and one copy of the
+library is unloaded, but there are remaining copies, the
+@var{still-in-use} field will be @samp{true}. In all other
+situations, the @var{still-in-use} field will have the value
+@samp{false}.
+
The @var{thread-group} field, if present, specifies the id of the
-thread group in whose context the library was unloaded. If the field is
-absent, it means the library was unloaded in the context of all present
-thread groups.
