Final refers to the minor version number, not the major. Meaning you are not running the beta or release candidate of 6.9.

We do plan for a parting update. Now that 7.6 is out, we have some cycles to work on it. However, one of my lead engineers is on vacation for a few weeks and will only be able to work on it towards the end of June - July. If we can resolve a particular issue then we may extend support for 6 but currently it is much more difficult to push updates to 6 than 7 due to certain issue we are working to resolve.

It is a good idea though to make plans to move to 7 or to at least test it.
