Why LSTMParameter code isn't merged?

[sohey-miyazaki]

I want to use LSTM layer.
So I try to make prototxt within LSTM layer.
But terminal says "Message type caffe.LayerParameter has no field named lstm_param".

And I checked source code.
I found that lstm_param's code is not in "caffe.proto".
(lstm_param's code is in junhyukoh/caffe-lstm repository)

Why LSTMParameter code isn't merged in main repository?
Is some reason existed?

It is merged, and has been in Caffe master since #3948 in April.

For usage questions about LSTMs + recurrence and other modeling questions, please post on the mailing list.

From https://github.com/BVLC/caffe/blob/master/CONTRIBUTING.md:

Please do not post usage, installation, or modeling questions, or other requests for help to Issues.
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

Thanks for your information.
I understand the situation.
