Hi all, I would like to quote an issue<https://github.com/apache/incubator-mxnet/issues/11072> sent from Sandeep: ```
We should always show Deprecated warning message for deprecated API. For example, I used mx.sym.SoftmaxActivation() API, but, it was deprecated in favor of mx.sym.softmax(). However, I never saw a warning message. Similarly, we should identify and warn for all deprecated API usage. ``` I think we should add something to the API to label them deprecated and this process should be done automatically. Currently, these pieces of information appear in the Description of the function, which can be extracted using this C API: “mxSymbolGetAtomicSymbolInfo”. “.. note:: `Concat` is deprecated. Use `concat` instead.” Regex can be used to determine whether the API is deprecated or not. Thanks, Qing
