From a commit on the referenced branch:
> Observer: correct inaccurate documentation of the .client file format
> The examples and all known implementations were correct.
The rest of the branch improves and clarifies documentation of .client files, and declares the serialization to be a subset of that of parameter defaults in .manager files (so we only need to add new serializations in one place).
Fixed in master, will be in 0.19.2
