We could also add a screenshot showing how crate versions published via trusted publishing look like

We should probably add a few words about now supporting the rendering of alert blocks in READMEs.

I would mention that trusted publishing for now only works on GitHub Actions.
And maybe mention that future CI providers might be supported in the future?

there are already four images in the blog post now. IMHO one per topic is sufficient.

@rust-lang/crates-io would be great to get an approval so that we can ship this before I go on vacation at the end of the week 😉

@rust-lang/inside-rust-reviewers could I also get a review from your group? 🙏

I was curious to test this interesting oxipng tool you mention in the blog post 😉

• docs-rebuild-confirmation.png resolution down from 2160p to 1600x1200, reduced color palette, size down to 40%
• readme-alerts.png and trustpub-settings.png colors optimized with oxipng, size down to ~50%

wdyt @Turbo87 ?

updated files

IMHO that's something that the build tool for the blog should take care of, but sure, I ran the files through oxipng now and rebased.
