This is something that is now surfaced via hg.m.o's json API & I don't think is something we should track in Treeherder. To my knowledge it's unused in Treeherder.

Commit pushed to master at https://github.com/mozilla/treeherder https://github.com/mozilla/treeherder/commit/6b1e4f602bafa7c8738c1dffe6f211233bfbcc1f Bug 1178234 - Remove repository_version Since it's unused, and hg.mozilla.org now has this information available via its API. Note: This commit depends on bug 1178719, to prevent issues during deployment. Also, due to https://code.djangoproject.com/ticket/25036 a migrate will need to be run interactively after deployment, to clean up the old repositoryversion content type.
