+[[v3.1_command_buffer_listvar]]
+=== List of buffer local variables
+
+The command `/buffer localvar` has been renamed to `/buffer listvar`.
+
+The option `localvar` is still supported to stay compatible with scripts
+calling it or referencing it in the documentation. +
+It is deprecated and will be removed in a future release.
+
+New options `setvar` and `delvar` were also added in command `/buffer`,
+see `/help buffer`.
