Good morning, it's Friday, November 6th, 2026.
The headline: Vue's new Vapor runtime is getting correctness fixes to match classic rendering, while server-side work is focused on real performance wins for large component trees.
First, Vapor parity. Content waiting behind a suspense boundary was starting its enter transition too early, before it became visible. Pull request 16158 fixes that timing for nested content, teleports and transition groups. A related merged fix, pull request 16156, keeps directive mount hooks on their own…
Second, performance driven by production profiling. Pull request 16153, now merged, keeps compiled slots for plain elements in push mode during server rendering, instead of building full virtual nodes only to serialize them. That matters for wrapper components that pass slots straight through. Pull request 16154…
Third, more control for build tools. Pull request 16155 proposes a resolve component compiler option, so tools like Nuxt can turn a tag directly into an import at compile time. Pull request 16152 fixes warning handling in single-file components, honoring a custom warning handler in production builds and surfacing…
What's next: the performance and…
