+## 1.0.2
+
+* Increase upper-bound of http-client to <0.5.
+* Avoid ever posting `null`. Some metrics that are `Double` may post `null` if
+  they are NaN or infinity - in this case we filter the submissions out.
+
 ## 1.0.1
 
 * Relax dependencies for aeson, http-client, text, network and network-uri.
