+## [1.4.0]
+
+### Upgrade Notice
+
+This update includes updated `EnvoyFilters` for `authservice` to fix #65 and is a component of a future upgrade to istio 1.8 (#191).
+
+__After upgrading BigBang to this version, you must follow the steps below to ensure apps protected by `authservice` are still protected.__
+
+In order to ensure sso for all services protected by `authservice` remain functional (`kiali`, `jaeger`, `prometheus`, and `alertmanager`), the `istio-proxy` sidecar attached to the `haproxy` infront of the services must be updated to `1.7.7`.
+
+The easiest way to do this is to cycle the pod:
+
+```bash
+kubectl delete po -n authservice -l app.kubernetes.io/instance=authservice-haproxy-sso
+```
+
+> __Note__: these 4 services (`kiali`, `jaeger`, `prometheus`, and `alertmanager`) will be unavailable for ~10s while the pod cycles. In the future we aim to provide an HA implementation of authservice's haproxy so the above operations can happen without downtime.
