On helm website you can find some plugins. One of them called helm-diff, and it can generate diffs between releases.

Here is how to use this plugin:

$ helm diff release -h

This command compares the manifests details of a different releases created from the same chart

It can be used to compare the manifests of

 - release1 with release2
    $ helm diff release [flags] release1 release2
   Example:
    $ helm diff release my-prod my-stage

Here is explained how to install the plugin. TLDR: if you are using helm version > 2.3.x jest run:

helm plugin install https://github.com/databus23/helm-diff

Let me know it this solves your problem. If you have any further questions I'd be happy to answer them.
