Next.js 16 + Turbopack Compatibility: What's the timeline for fixes and new releases?

[SergiusDu]

Context

Since the official response in Discussion #1442 (Aug 2025), @dcousens mentioned that Keystatic is actively maintained internally and that a community update with refreshed roadmaps would follow a new Keystone major release. That was ~7 months ago — no update has been published since.

Meanwhile:

• Next.js 16 made Turbopack the default bundler (Dec 2025)
• Issue #1501 documents a critical self-import bug in @keystar/ui@0.7.19 (keystar-ui-layout.js) that causes useGridStyleProps is not a function at runtime — making the entire Keystatic admin UI unusable under Turbopack
• The last commit to main was Dec 15, 2025 (3+ months ago)
• 12 community PRs (including trivial 1-line CSS fixes) remain unreviewed
• No npm release has been published despite the fix reportedly existing in the repo

Impact

For projects using @keystatic/next with Next.js 16:

• next dev (Turbopack) → Keystatic admin is a white screen, zero console errors
• next dev --webpack → works, but Webpack is now legacy in Next.js 16
• next build (Turbopack, default) → runtime crash on /keystatic

The only workaround is falling back to Webpack, which defeats the purpose of upgrading to Next.js 16.

Questions

1. Is there a timeline for publishing @keystar/ui@0.7.20 (or any release) to npm that fixes the Turbopack self-import issue?
2. Is there a plan to support Next.js 16 as a first-class target?
3. What would you recommend for users depending on Keystatic in production — is it safe to continue building on it, or should we plan for potential breaking changes with newer bundlers?

We understand open-source priorities shift — an honest status update would help the community make informed decisions. Thank you.

Agreed, and I think this goes beyond the Next.js/Turbopack issue — it's the silence that's the real concern. I'd love to use Keystatic in more of my projects, and even just a small update from the team would mean a lot to us all. 💜

EDIT: I'll take this back. A day after, plenty of PRs have been reviewed, thank you! ❤️
