Hi @Az-4342,
Thanks for you inquiry. I'll reach out to the product group to see if there's a tenative timeframe. In the meantime, if you need 12.17.x, one option is creating your own container.
EDIT: The product group is tenatively scheduled to release 12.18.0 in ~3 weeks due to the fact it's a security release https://nodejs.org/en/blog/vulnerability/june-2020-security-releases/
