+7.0.0 release adds image digests to all images in default values, for example:
+
+```yaml
+runtime:
+  engine:
+    image:
+      registry: quay.io
+      repository: codefresh/engine
+      tag: 1.174.15
+      pullPolicy: IfNotPresent
+      digest: sha256:d547c2044c1488e911ff726462cc417adf2dda731cafd736493c4de4eb9e357b
+```
+
+Which means any overrides for tags won't be used and underlying Kubernetes runtime will pull the image by the digest.
