Change	Applicability condition
Node.js 22.12 or newer required. `engines.node` narrows from the v4 and v5 range of `>=20.19 <22 \|\| >=22.12` to a flat `>=22.12`. Node 20 reached end of life in April 2026.	Check `engines.node`, `.nvmrc`, CI images, and the build host. Affects build and development environments only, not the Content Lake or the browser bundle.

Change	Applicability condition
`enableLegacySearch` config option removed. Use `search: {strategy: 'groqLegacy'}` instead.	Grep the config for `enableLegacySearch`.
React strict mode on by default in development. Opt out with `reactStrictMode: false` in `sanity.cli.ts`.	Applies to every project. It surfaces existing effect-cleanup and concurrent-rendering issues rather than creating new ones, so recommend leaving it on and fixing what it reports.
Default search strategy changed from `groqLegacy` to `groq2024`. Better performance on large datasets, deeper nested-content and Portable Text coverage, and wildcard, phrase, and negation syntax. Results, ordering, and counts shift because the query logic differs.	Applies unless `search.strategy` is already set. See below.

Version	Change	Applicability condition
6.3.0	*The Portable Text input dropped all legacy `data-slate-` attributes, CSS classes, and non-`pt` data attributes from its editing DOM.** Migrate to the `data-pt-*` equivalents.	`grep -rn "data-slate"` across source, stylesheets, and test suites. This is the highest-impact undeclared change in the v6 line and it fails silently. Custom CSS stops applying and end-to-end selectors stop matching, with no error.
6.2.0	The markdown plugin’s `config` prop deprecated in favour of `enabled`.	Only if `sanity-plugin-markdown` is configured with `config`.
6.2.0	Native browser autocomplete and autofill disabled on Studio form fields.	Informational.
6.4.0	`useDocumentVersionInfo` deprecated.	Grep for the hook.
6.6.0	Invisible stega metadata stripped from text pasted into plain-text fields.	Going forward, no action. Documents already containing stega characters need a one-time content migration using `stegaClean` from `@sanity/client/stega`. Only relevant if visual editing with stega is or was in use.
6.6.0	`menuItems([])` in structure configuration is now honored, so no default menu items are injected.	Applies if structure config uses `menuItems([])` and relied on the injected items appearing.
6.6.0	“Default sort” and “Default view” scoped to the individual document list rather than overriding every list of the same type.	Applies to structure customization that relied on the old spillover.
6.6.0	Opt-in table editing added to the Portable Text input, enabled with `plugins: {table: {enabled: true}}` on `components.portableText` plus a declared table schema.	Off by default, so no risk. Worth a note: do not enable it until every rendering surface can handle table blocks.
6.7.0	`Rule.uri({scheme})` respects a custom scheme when combined with other rules, so `mailto:` and `tel:` values are no longer wrongly rejected.	No action. Content that previously failed validation may now pass.
6.9.0	`sanity build` and `sanity deploy` now honor `deployment.autoUpdates`, which was previously ignored in some code paths.	Applies to every project with `autoUpdates` set. If a project set `false` but was receiving updates anyway, that stops. Verify which behavior the team expects.
6.9.0	`defineType`, `defineField`, and `defineArrayMember` preserve explicitly supplied optional properties on their return types.	Applies to any TypeScript project. Inferred types shift, so expect new type errors or newly redundant non-null assertions in schema-adjacent code. Usually quick to resolve.
6.11.0	`useClient` deprecation narrowed to the no-argument call. Calling `useClient()` without options warns; calling it with options, such as `useClient({apiVersion: '2024-01-01'})`, does not.	`grep -rEn "useClient\(\s*\)" src/`. The fix is to pass an explicit `apiVersion` rather than to stop using the hook. Worth doing regardless of the warning, because an implicit API version is its own latent problem.
6.10.0	The request-access screen was replaced with the shared `access-ui` package, which adds a `renderAction` slot.	Informational for most projects. Applies only if the access-request screen was customized or its markup was targeted by tests or CSS.
6.12.0	`displayName` assignments removed from `sanity` exports to unblock tree shaking.	Applies only to code or tests that identify components by `displayName`, including some snapshot and component-lookup patterns. Grep test suites, not just `src/`.
6.12.0	The mutator drops patch paths that cannot apply to the local document instead of throwing.	Informational. Relevant if custom code relied on the throw to detect a stale path.
