Adds the 2.19 entry to the "What's new" page.

Fixes #4404

Might have one more "what's new" entry if #4528 is ready in time

Thanks for working on this!

I’ll take a look early tomorrow. We can hold off on this one until the blog posts are released. I switched to draft to better signify that.

I thought I'd set it to draft 😅 thanks for catching that! Edit: I took it our of draft because my TODOs are done

We can hold off on this one until the blog posts are released.

So, the release blog post doesn't actually go out until the 25th. Idk if you want to wait that long. I could just remove that link until tomorrow.

I did just replace the author part of the draft urls (i.e. "mit-mit"/"mbelanger") with "dartlang", which is what they'll be once published, so at least they're not broken links

Hmm, maybe "What's new on dart.dev" is not the best new page title, since the first sentence says "This page describes what’s new on the Dart website and blog"... Thoughts?

About the language evolution page:
Since this page is just about language changes, should I skip mentioning things that are more... idk, package-related? I.e.:

• package:js @staticinterop annotation?
• pub changes?
• Isolate.run?

I think it makes sense to keep "What's new" released on the same day as those, especially with all the blog links, but am happy to get in it today if you'd like. We've had mismatch before during 2.13 and that's what we did since there's no need to rush this page update.

Consider separating the language evolution changes to a new PR targeting the main branch (after fetching the latest changes there), as those would be nice to get in.

I didn't consider that, thanks for pointing it out. I guess it's fine to stick to the old title since on the website we only link to it with context. I do get this as the first search result for "What's new in Dart" so it is a tad confusing, but we do link to the blog posts and changelog so it's probably okay.

Since this page is just about language changes, should I skip mentioning things that are more... idk, package-related? I.e.:

Yep! We should skip those pieces :) - We use the page for primarily pure language changes, outside of a few minor exceptions before.

I really love both these additions! You were so thorough :D

Oh I definitely still think the name should change, more so now that you've pointed that out. I just meant "...on dart.dev" doesn't make sense, so maybe "What's new in Dart documentation" or "What's new in Dart docs"? Just a question of sound/feel (better ideas welcome 😅 )

Wow, a very impressive list! Especially given that this was all after Kathy resigned. lgtm

[parlough]

Thanks for the review @sfshaza2. Marya did a great job with this list and release :)

Some final comments/suggestions then looks good to me. Thanks @MaryaBelanger!
