+This release addresses a potential security vulnerability.
+
+If you do not use TypedArrays, then you're fine (but should still
+upgrade for other reasons, like better performance and npm
+peerDependencies.)
+
+If you use TypedArrays, you should upgrade to v0.8.17 as soon as
+possible.  If user input can affect the size parameter in a
+TypedArray, an integer overflow vulnerability could allow an attacker
+to write to areas of memory outside the intended buffer.  Please
+upgrade ASAP.
