In the context of SYSTEMML-554, we aim to introduce native frame data type support. While porting the file-based transform, I intend to drop the existing transform scaling functionality (mean substraction, z-scoring) as it is more naturally expressed over matrices. However, this change raises a general question with regard to our documentation:
How do you feel about maintaining version-specific language references? It would certainly help to avoid version-specific conflicts (e.g., builtin functions added in newer versions) but it might add overhead as fixes would need to go into multiple versions. Personally, I would be in favor of simply archiving the old documentation (but keeping it available) as part of our release process. Regards, Matthias
