@Jefiozie the stamping does not seem to be working.

[Jefiozie]

Is this local with ng serve? If that is the case then it could be possible. At this moment we only support production bundles that are hosted via a webserver. If we would like to support the command ng serve we should make some changes.

Actually I checked this on the Netlify preview URL: https://deploy-preview-390--xlayers.netlify.app/

[Jefiozie]

What scripts do we run for netlify? Could you show/ tell me

[manekinekko]

I think it's npm run build. So you can run the stamp process in a postbuild script

[Jefiozie]

With the latest adjustments, this should be fixed for all of our builds that are run via: `npm run build, see also the netlify preview

@manekinekko, I think this one is done now and ready for review and merge.
