😊 Welcome! This is either your first contribution to the Istio documentation repo, or
it's been a while since you've been here. A few things you should know:

• You can learn about how we write and maintain documentation, our style guidelines,
  and the available web site features by visiting Contributing to the Docs.

• In the next few minutes, an automatic preview of your change will be built with
  a full copy of the istio.io website. You can find this preview by clicking on
  the Details link next to the deploy/netlify entry in the status section of this
  page.

• We care about quality, so we've put in place a number of checks to ensure our documentation
  is top-notch. We do spell checking, sanitize the Markdown, ensure all hyperlinks point to a
  valid location, and more. If your PR doesn't pass one of these checks, you'll see a red X in the
  lint_istio.io entry in the status section. Click on the Details link to get a list of the
  problems with your PR. Fix those problems and push an update; this will automatically re-run the
  tests. Hopefully this time everything will be perfect!

• Once your changes are accepted and merged into the repository, they will initially show up
  on https://preliminary.istio.io. The changes will be published to https://istio.io
  the next time we do a major release (which typically happens every 3 months or so).
  To publish them sooner, add a cherrypick/release-x.xx label, where x.xx is the current
  release of Istio.

Thanks for contributing!

Mitch presented this in today's TOC, the consensus is to publish it as 2025/2026 roadmap given we are already in July 2025.

cc @istio/technical-oversight-committee @istio/steering-committee for review

only q i have is "Multi-cluster ambient mesh will be available as an Alpha in Istio 1.27, which we plan to release in August." Is this on schedule? would it steal the thunder from the 1.17 release blog which comes up soon in Aug?

Two nits, but otherwise LGTM!

I don't think it will steal any thunder; the implication I think Mitch wants is that it is close.

"Multi-cluster ambient mesh will be available as an Alpha in our upcoming Istio 1.27 release." or just "an upcoming release" if you want to hedge

Yes, this has already merged to 1.27.
