That is one of the reasons we provide patches if possible.
When you have a subscription style update system, it means that you potentially get sizeable updates without a separate upgrade payment (like 2.0 being included with an active license). The flip side is that you may not get all bug fix releases.
We can't guarantee that we make a patch available as it depends on the issue, but we certainly do our best. Technically, we don't even lock patches down to license holders.
