How often does the Leather Jacket come around from Levis?

Just out of pure curiosity, does Levi's Vintage release the Skyfall jacket every autumn? What's the release schedule like?

Is it a different jacket every season or year? I only see the black Menlo Cossack (nothing to do with Trevelyan RIP) jacket available and recall a slight variation of the Skyfall jacket being available last year.

Thank you!
