Timeline is a section in the Project dashboard view. This is a global changelog for your project, showing you all the important quality and lifecycle changes that happen to your codebase.
Recent changes for our frontend app
There are a few main types of events we report on - namespaces being added or deleted and their quality improving and degrading. When you hover on any of these changes you will see a 'Compare Changes' button (see above) that will show you what exactly changed in a namespace. For namespaces being added or removed the change will be respectively represented by a green and red diff.
