Does a build of Alfresco 5.1.5 Community edition exist? If so where can I download it from?
5.1.5 is an Enterprise release,
5.1.e is the last Community release IIRC.
Edit: 5.1.e was the last 5.1 Community release IIRC.
Latest version is 6.1 General release and 5.2 General release was the previous version. You can find community versions here for download: https://www.alfresco.com/thank-you/thank-you-downloading-alfresco-community-edition
If you are looking for older community versions for download, visit here: https://sourceforge.net/p/alfresco/activity/?page=0&limit=100#5772888534309d1e098ef7cb
Hope this helps.
Thanks Daan and Abhinav, I will check those out
