+#### Fixed
+
+- In the event of a `no memory` error returned by the L2 lua_shared_dict cache
+  (after the number of `shm_set_tries` failed), we do not interrupt the `get()`
+  flow to return an error anymore. Instead, the retrieved value is now bubbled
+  up for insertion in L1, and returned to the caller. A warning log is (by
+  default) printed in the nginx error logs.
