Fixed Grid Column Stacking Flash on SSR (#5628)
Grid columns configured to stack at a specific breakpoint would briefly render side-by-side on page load before snapping to stacked layout — or stay broken entirely if the content didn’t hydrate. This happened because stacking was resolved in JavaScript after hydration, not from the actual viewport width.
Stacking is now applied via a scoped CSS media query rendered in the HTML, so the browser applies the correct layout immediately based on viewport width — no JavaScript required, no layout flash.
Infrastructure
Infra.VpcWithenabled=Is Now Respected in Production (#5631)
Adding <Infra.Vpc enabled={false} /> to webiny.config.tsx had no effect on production environments. Production environments receive a VPC by default, and that default overrode the explicit setting, so the VPC was still created with no error or warning. An explicit false now wins. Leaving the extension out still means “VPC for production environments only”, so nothing changes for projects that were not already asking for enabled={false} and being ignored.
Turning off a VPC that is already deployed is a destructive change, not a config tweak. Pulumi tears the VPC down and moves your Lambdas out of it. The core app must deploy before api, because api reads subnet and security group IDs from core’s stack outputs. Review pulumi preview before deploying.
Webiny SDK
Fixed Unchecked Result Access Causing Cryptic Errors (#5625)
When using the Result pattern internally, accessing .value on a failed result would break code execution with no meaningful error message. All Result values are now properly checked before access, preventing these cryptic failures and improving error handling throughout the codebase.
