Any news?

For those who missed that news, if we are lucky then we could have this in spring 2025

Thanks for engaging on this all, this is on our list to get to in the early part of next year. Right now we are re-working the services in Actions which do our YAML expansion (focusing on how we improve their availability). Once we are live with the new services we will start looking at adding features and this is on our list <3

I didn't expect any movement on this feature as this has been requested for years.

YAML anchors are now shipped :) marking this as closed. I know there are some asks for merge keys, I would ask for a new feedback issue for this so we can track it :)

As an FYI our logic was to provide what's in the yaml 1.2 spec and merge keys aren't in there. I know this spec is ~15 years old now :) so we are open to the feedback, but want a fresh issue so it's easier to count the 👍 to understand where we put energy next
