hi @mrtj i think you'll need to rebase to pull in the latest changes to fix the workflows

formatter=lambda span: span.to_json() + linesep, is the default behavior so there's no need to introduce additional method (i.e. linesep) here. I would prefer to remove formatter arg. I'm fine about the out arg since it's good to have for users.

In addition, could you move this section after Custom Attribute Tracking? This configuration is more advanced than attributes setup.

[mrtj]

It is true that the lambda function above implements the default behavior, but I wanted to show in the documentation that the formatter can indeed be customized. I considered using an alternative serializer, but ultimately concluded that the default is good enough.

I've changed the section order.
