Alfresco 3.4.e SDK download

[chirayu]

Hi,

Could anyone please let me know from where can I download the SDK for Alfresco 3.4.e community version?

Thanks,

No there will never be an Enterprise 3.4.X with Activiti. 

Activiti will be supported in Alfresco Enterprise 4.0.X

Would it be possible to integrate Activiti BPMN 2.0 BPM engine  with some other Enterprise version to create workflow customizing it? If yes can you provides some help how to do that?
