Webb installer - when will versions NC12.5 and 13 be availabel?

I am on a shared server with NC12.3. That installation went very smooth. It is still an experimental installation and I want to upgrade before going sharp. The current webb installer is NC12.4.

I wonder when the next version will be available? Or can I upgrade manually? Afraid I will miss something. Would prefer webb installer as I had a good experince of the previous installation.

I also have another NC13 on a VPS server. Want to upgrade the shared server to evaluate if it suits me well enough.
