 * The `hash_mod` relabeling action now uses MD5 hashes instead of FNV hashes to

+Future breaking changes / deprecated features:
+

+  instead.
+* Support for filter operators between two scalar values (like `2 > 1`) will be
+  removed in the future. These will require a `bool` modifier on the operator,
+  e.g.  `2 > bool 1`.
