Fixed Full-Text Search onsearchableJsonFields for OpenSearch Deployments (#5683external link)
anchor

{/ REVIEW-PENDING @brunozoric — confirm this entry, then delete this line /}

Full-text search on models with searchableJson fields returned empty results on DynamoDB + OpenSearch deployments. This affected the Website Builder’s page search, where the properties field stores page metadata as a searchable JSON object.

The underlying issue was that the search query targeted the object field name itself rather than its nested leaf values. Since OpenSearch cannot match text inside an object reference, every search query returned zero hits. DynamoDB-only deployments were unaffected because they flatten object values in memory during filtering.

The fix ensures searchableJson fields now resolve to their nested leaf values (values.<storageId>.*), restoring expected search behaviour across all deployment configurations.

ExposeminimumProtocolVersionfor Custom Domain CloudFront Distributions (#5680external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

When configuring custom domains for Admin or API distributions, you can now set the CloudFront TLS security policy directly through the extension configuration. Previously, changing this required patching @webiny/project-aws.

import { extensions } from "webiny/infra";

extensions.addExtension({
  type: "Infra/Admin/CustomDomains",
  params: {
    domains: ["admin.example.com"],
    certificateArn: "arn:aws:acm:...",
    minimumProtocolVersion: "TLSv1.2_2021"
  }
});

Supported values match the full CloudFront policy set: SSLv3, TLSv1, TLSv1_2016, TLSv1.1_2016, TLSv1.2_2018, TLSv1.2_2019, and TLSv1.2_2021. The parameter is optional and omitted from the CloudFront configuration when not set, so existing distributions see no change.

Fixed React Server Component Crash When Initializing the Content SDK (#5677external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

Version 6.4.10 introduced a bug where initializing the Website Builder SDK from a React Server Component would throw TypeError: viewportManager.setBreakpoints is not a function. This happened because the viewport manager is a client-only module, and RSC receives a client reference instead of the actual function. The issue blocked page loading and redirect resolution entirely when using RSC.

This release reverts the change that caused the crash. Grid column stacking returns to the 6.4.9 behaviour: it resolves on the client after hydration rather than during SSR. Mobile visitors may see a brief flash of the desktop layout before the correct mobile layout applies.
