# Context and KBs now power the Ask AI agent, plus new guides and improvements across the platform **Version:** v2026-10-30 **Published:** October 30, 2026 This month we added new guides for dataset environments, upgrading older `@sanity/client` versions, and diagnosing API request spikes. The docs site also adds an improved “Ask agent” feature, powered by Sanity Context and Knowledge Bases. ## New and updated docs ### Datasets, environments, and limits - New guide: [Development, staging, and production environments](https://www.sanity.io/docs/content-lake/environments) explains how drafts, releases, preview, separate datasets, Cloud Clone, and export and import fit together across environments. - [How to use Hot Swapping for datasets](https://www.sanity.io/docs/content-lake/how-to-use-hot-swapping-for-datasets) now lists what doesn't work through a dataset alias, and scopes hot swapping to recovery and breaking migrations. - [Drafts and versions](https://www.sanity.io/docs/content-lake/drafts-and-versions) (previously Drafts) now covers both draft and version documents. - [Backups](https://www.sanity.io/docs/content-lake/backups) clarifies which plans include backups, that you turn them on per dataset, and how to confirm they're running. - [Technical limits](https://www.sanity.io/docs/content-lake/technical-limits) adds the limit of 200 active releases per dataset, and clarifies that document limits are plan quotas counted across datasets. ### Studio - New guide: [Archive documents without deleting them](https://www.sanity.io/docs/studio/archive-documents) compares unpublishing, an archived field, deleting and restoring, and unpublishing in a release. - New guide: [Reorganize your structure without breaking links](https://www.sanity.io/docs/studio/reorganize-structure-without-breaking-links) shows how to rename and move Structure Builder items without breaking saved URLs. - New guide: [Re-enable browser autocomplete on Studio fields](https://www.sanity.io/docs/studio/re-enable-browser-autocomplete) covers per-field and studio-wide overrides. - [Validation](https://www.sanity.io/docs/studio/validation) shows how to restrict publishing by user role with `context.currentUser`. - [Handle intents in the Structure Tool](https://www.sanity.io/docs/studio/handle-intents-in-structure) explains how to route documents of the same type to different lists based on a field value. ### Client libraries and APIs - New guide: [Upgrade @sanity/client from an older major version](https://www.sanity.io/docs/apis-and-sdks/js-client-upgrade) covers the breaking changes in each major version from v3 to v8. - [Advanced client patterns with @sanity/client](https://www.sanity.io/docs/apis-and-sdks/js-client-advanced) adds error handling and routing requests through a proxy. [Working with assets in @sanity/client](https://www.sanity.io/docs/apis-and-sdks/js-client-assets) adds upload progress tracking. - New guide: [Diagnose an API request spike](https://www.sanity.io/docs/platform-management/diagnose-api-request-spikes) helps you find the cause of unexpected API usage with your request logs. - [Add live content to your application](https://www.sanity.io/docs/developer-guides/live-content-guide) covers private datasets, and the new [Relay live draft updates through your server](https://www.sanity.io/docs/developer-guides/relay-live-draft-updates) guide shows how to get draft-aware live updates without a token in the browser. - [Command Line Interface (CLI)](https://www.sanity.io/docs/apis-and-sdks/cli) now lists the CLI's requirements, including the hosts to allowlist on restricted networks. ### Media Library and assets - New guide: [Update an asset to a new version with the API](https://www.sanity.io/docs/media-library/update-asset-versions). - New guide: [Use Media Library with AI agents](https://www.sanity.io/docs/media-library/mcp) covers the Media Library tools in the Sanity MCP server, including uploading files from your computer. - [Working with video](https://www.sanity.io/docs/media-library/working-with-video) shows how to get static MP4 renditions of Media Library videos. - [Assets](https://www.sanity.io/docs/content-lake/assets) and [Keeping your data safe](https://www.sanity.io/docs/content-lake/keeping-your-data-safe) clarify that dataset assets are always public on the asset CDN, even in private datasets. ### Functions, Blueprints, and App SDK - New guide: [Manage stacks](https://www.sanity.io/docs/blueprints/manage-stacks) covers listing, inspecting, and removing Blueprints stacks. The stack limit is now correctly listed as 10 per scope. - [Add environment variables to functions](https://www.sanity.io/docs/functions/function-env-vars) documents the 4KB size limit, and [Functions cheat sheet](https://www.sanity.io/docs/functions/functions-cheatsheet) shows how to keep functions from running during an import or sync. - [Create a PubSub function](https://www.sanity.io/docs/functions/pubsub-function-quickstart) explains that PubSub functions only run when another function invokes them. - [App SDK deployment](https://www.sanity.io/docs/app-sdk/sdk-deployment) shows how to turn on auto-updates for App SDK apps, and warns against putting secrets in `SANITY_APP_` environment variables. - [App SDK and TypeGen](https://www.sanity.io/docs/app-sdk/sdk-typegen) is rewritten for the `typegen.resources` workflow, with a new [Migrate from experimental TypeGen in the App SDK](https://www.sanity.io/docs/app-sdk/migrating-from-experimental-typegen-in-app-sdk) guide. ### Sanity Context and Content Agent - [Context MCP tools](https://www.sanity.io/docs/ai/sanity-context-mcp-tools) adds the `knowledge_base_search` tool. The Context MCP no longer reads a `tools` URL parameter, so [Context MCP reference](https://www.sanity.io/docs/ai/sanity-context-mcp) and [Inline initial context into your system prompt](https://www.sanity.io/docs/ai/sanity-context-initial-context) now cover filtering tools on the client side. - [Content Agent for Linear](https://www.sanity.io/docs/content-agent/content-agent-for-linear) is now in the Content Agent navigation, and the Slack and Linear guides explain when the agent can publish. - [Get started with Sanity Content Agent](https://www.sanity.io/docs/content-agent/introduction) adds the registration step for self-hosted studios. ### Organizations, billing, and access - New: [Spending alerts](https://www.sanity.io/docs/platform-management/spending-alerts) explains how to get notified as your organization's overage spending grows. - New: [Export activity to Google Cloud Storage](https://www.sanity.io/docs/platform-management/export-activity-to-google-cloud-storage) and the [Activity Feed Export data reference](https://www.sanity.io/docs/platform-management/activity-feed-export-data-reference). - [Set up single sign-on with SAML](https://www.sanity.io/docs/developer-guides/sso-saml) explains that role mapping is additive, applies at first login, and doesn't remove users who leave your identity provider. - [Document mutation patterns](https://www.sanity.io/docs/content-lake/mutation-patterns) and [Build a custom role with the Access API](https://www.sanity.io/docs/content-lake/build-a-custom-role-with-the-access-api) explain that purging history requires the `editHistory` permission, which no predefined role grants. ### Astro The Astro docs now recommend the Sanity-maintained `@portabletext/astro` package (a fork of the community package), and [Configuring @sanity/astro](https://www.sanity.io/docs/astro/configure-sanity-astro) documents the `clients` option added in `@sanity/astro` 3.6.0. ## Platform updates ### Ask agent, powered by Sanity Context The docs site's AI assistant is now powered by [Sanity Context](https://www.sanity.io/docs/ai/sanity-context) and [Knowledge Bases](https://www.sanity.io/docs/ai/sanity-context-knowledge-bases), the same tools we document for building your own agents. - Open it from the “Ask agent” button. - Use Ask about this page on any article to ask a question with that page as context. - Type a question into search and send it to the Ask agent. ### Smaller improvements - Code blocks have a Copy link button, so you can link straight to an example. - Deep links to a code block or heading that is otherwise not rendered (hidden inside a tab, collapsed inside a snippet, etc) will automatically show and render on load. - We now check the docs for broken internal and external links on a schedule, and block redirects that would break existing pages.
