 * Add optional imagePullSecrets to ServiceAccount using `serviceAccount.pullSecret` from values.yaml. If pods do not have imagePullSecrets (eg without `image.pullSecret` in values.yaml), k8s populates them from the ServiceAccount. (#196) (by @cognifloyd)
 * Reformat some yaml strings so that single quotes wrap strings that include double quotes (#194) (by @cognifloyd)
 * st2chatops change: If `st2chatops.env.ST2_API_KEY` is defined, do not set `ST2_AUTH_USERNAME` or `ST2_AUTH_PASSWORD` env vars any more. (#197) (by @cognifloyd)
-
+* New feature: Shared packs volumes `st2.packs.volumes` -- Instead of using `st2packs` images to install packs, allow using cluster-specific persistent volumes to store packs, virtualenvs, and (optionally) configs. This enables using `st2 pack install`. (#199) (by @cognifloyd)
 
 ## v0.60.0
 * Switch st2 version to `v3.5dev` as a new latest development version (#187)
