I installed the Alfresco Community 201605 GA on two machines. I am not sure if I download the installer on two separate occassions. However, I have one version of 201605 GA as Alfresco 5.1.f and the other 5.1.g. Though if I use the admin console (http://url/alfresco/service/admin), I get two different versions, being 5.2.0 (r125711-b6) and 5.1.0 (r127059-b7). Could it be that I download and EA without noticing; or did I mess up somehow significantly?
