Each release of the ET should have tags in the repositories identifying the release, as well as any minor version increments due to backports. We have tags for ET_2013_05_v0 but not for ET_2013_11_v0. It would also be good to create new tags based on the branch every so often after fixes have been backported, so that it is possible to easily identify a specific version of the toolkit, e.g. ET_2013_11_v1.
Frank is going to create ET_2013_10_v0 tags.
