XF 1.4 Xenforo 1.4 Still supported?

[ActorMike]

I cannot update my board to 1.5 because I'm using the BDPaygate with Authorize.net and I cannot confirm if that works or not on 1.5, so for the time being are you going to continue supporting 1.4 in regards to security updates etc?

We can't always explicitly guarantee support for old versions of XenForo, but I can confirm that recently when we had to release a security fix, we did also patch XenForo 1.2:

So, realistically, you should be fine to stick with 1.4.10.
