Jit Model Forward Compatibility with new PyTorch Release

Dear community, May I ask a question regarding to Jit Model Forward Compatibility?
If I generated a Jit Model with old version PyTorch release (save it as jit.save), Does it guarantee to be runnable with new PyTorch release (load it with jit.load)? If so, where can I find the link of claim?

There aren’t any forward compatibility tests [JIT] Serialization forward compatibility tests · Issue #49585 · pytorch/pytorch · GitHub

That said JIT is in maintenance mode so it’s unlikely anyone is going to be making any breaking changes here
