It's not clear if there is anywhere to find the shipped & upcoming features "in the works"* for Jira Software Classic Projects.
For the Next-Gen projects, it's very clear when you go to "What's New" -> Next-Gen you https://www.atlassian.com/software/jira/whats-new/next-gen#results
But what about Classic projects? Is this supposedly spread around the other categories (Core, etc.)? Is this somewhere else that can be tracked publicly?
For the last years it feels that the development efforts are focused on Next-Gen, and new features are coming to Classic after the fact (like Roadmaps). Of course each project type has a different development maturity, but the underlying message is that Classic will eventually be left behind.
Any information on this regard from Atlassian themselves or the community is more than welcome.
* I'm avoiding the term "roadmap" not to be confused with the actual Jira feature with the same name
