+### To 1.0
+
+Chart release 1.0 reflects a major bump of the default NGINX Exporter image tag from major number 0 to 1.
+
+This release has switched to using flags in the new format (`--flag`) but still supports the
+deprecated format (`-flag`) transparently for NGINX Exporter below release 1.0.0.
