@Akiyamka note that there are more than one instance of the changelog site out there so we need to softcode the URL into the site configuration.

e.g. here https://github.com/kartoza/prj.app/blob/develop/deployment/.env.example

I looked at how it is done for intercom and assumed that it would be correct to do the same for matomo. Is that correct?

@dimasciput could you review and deploy on qgis changelog please?

@Akiyamka I think implementing django-matomo like you did in https://github.com/qgis/QGIS-Django/pull/320/files is a good way for django based projects. Thus, in the existing settings files, matomo variables can be loaded from the environments variables using os.environ that are specified in the .env generated from the sample .env.example.

@Akiyamka The django-matomo template can be customized. To disable cookies, for example: qgis/QGIS-Django#333
