due to preview features, a 2D release-vs-features grid might be helpful

[kevinb9n]

This is just an idea, please feel free to discard it

I jotted this table and have needed to refer to it a couple times... you might find this kind of format useful here too, I dunno.

... the numbers being JEP links

[cayhorstmann]

I agree that would be useful. If not easily automated, I could maintain it as part of https://javaalmanac.io/features/

I like the idea. I'll play with it how this can be rendered in a scalable way.

Cool - in case it helps, here's the sheet, where I got a wee bit further than shown.

@kevinb9n Do you have any idea how we can render the matrix for > 25 Java versions and hundreds of JEPs?

[cayhorstmann]

I don't think that would be too hard. Keep the first column fixed, like in https://stackoverflow.com/questions/1312236/how-do-i-create-an-html-table-with-a-fixed-frozen-left-column-and-a-scrollable-b

As a first step we need to prepare the data. Currently all JEPs live on their own. I propose a new optional value

features[].predecessors[]

having the same schema like refs (type and ref). Currently the data for Java 21 looks like this:

https://github.com/marchof/java-almanac/blob/master/site/data/jdk/versions/21.json

[cayhorstmann]

The data is on https://chriswhocodes.com/jepsearch.html, and I can scrape it. Or we can ask Chris for a JSON feed.

@cayhorstmann We already maintain all the JEP info in our repository with some manual additions (like whether a JEP is a preview). For consistency I would prefer to keep using the Java almanac data: https://github.com/marchof/java-almanac/blob/master/site/data/jdk/

@marchof Created a PR for this. Let me know what you think!

Here is another nice matrix: https://minijug.org/jeps.html
