 ## Upgrading
 
+### To 5.0.0
+
+Deprecated options `auto-discover-databases`, `constantLabels`, `exclude-databases` & `include-databases` has been removed.
+Deprecated custom query config has been removed.
+Deprecated PodSecurityPolicy and K8S beta API versions have been removed.
+Chart.yaml appVersion field is used as default image tag.
+Labels are templated now.
+Add default securityContext and PodSecurityContext.
+LivenessProbe timeout has been raised to 3.
+
 ### To 4.6.0
 
 This release adds functionality to template the variables inside `config.datasource` by means of allowing the `tpl` function in the resources that make use of it. This functionality is useful when you want to do sub-charting (e.g. in a postgres chart) and you want to avoid the duplication of variables inside `config.datasource`.
