Unfortunately, XenForo looks to be on about an 18 month cycle for major releases. For admins, like me with absolutely no patience, that is an awfully long time to wait for some new stock features to arrive.
It's probably also a cause for revenue loss for XenForo since many will not renew licensing for bug fixes that may not affect them enough to constitute renewing before new features are available. This can cause XenForo to lose out on up to 6 months of renewal revenue every year and a half. If that doesn't help motivate them to get onto a 12 month major release schedule nothing will.
