+- Support for shared memory IPC:
+
+  - ``LRU.evict()`` can now manually evict specific keys, overriding priority
+  - ``Buffer`` has gained the option to preserve keys in ``slow`` when they are
+    moved back to ``fast``
+  - New method ``File.link()``, which acquires a file-based key from another source
+    (e.g. a different memory-mapped File object)
+  - ``File`` never reuses filenames in order to avoid race conditions with other File
+    objects calling ``link``
