Which stable GHC release is expected to have support for linear types?

I think I figured it out meanwhile: The linear types extension is
enabled all the time.
I had thought about this possibility already, but then concluded that
this was not the case, since types of the form a -o b were not
supported. However, when looking at the diffs, I discovered that at the
moment, only the Unicode syntax a ⊸ b is understood.
All the best,
