What is Sanity?

Sanity is making the fastest path into its platform an agent typing a CLI command.

Sanity releases across many independently versioned packages at once — Studio, @sanity/ui, the MCP server, the React App SDK and Media Library — often several in the same week. Early August carried two directional moves within a day of each other: @sanity/ui v4.0.0 went ESM-only behind subpath imports, and Studio v6.9.2 shipped Sanity New, account-less project creation explicitly aimed at AI agents. The rest of the cadence is steady corrective work on Studio and Media Library.

What is Vitest?

Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.

Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.

Sanity is making the fastest path into its platform an agent typing a CLI command.

◆ Current state

Sanity releases across many independently versioned packages at once — Studio, @sanity/ui, the MCP server, the React App SDK and Media Library — often several in the same week. Early August carried two directional moves within a day of each other: @sanity/ui v4.0.0 went ESM-only behind subpath imports, and Studio v6.9.2 shipped Sanity New, account-less project creation explicitly aimed at AI agents. The rest of the cadence is steady corrective work on Studio and Media Library.

◆ Where it's heading

Two currents run in parallel. The platform is being made agent-addressable: the MCP server can now run Sanity CLI commands without a shell, patches documents transactionally, and refuses to write to Studio-managed schemas, while project creation itself no longer requires an account. At the same time the front-end stack is being modernized without much regard for laggards — ESM-only, Node.js 22.12, React 19.2, styles as an imported stylesheet, deprecated APIs removed outright. Sanity is optimizing for teams and agents starting fresh rather than for consumers pinned to old toolchains.

◆ Prediction

Sanity New issues temporary credentials with a 72-hour window before a project must be claimed, and the MCP server is iterating weekly; the observable pattern points to the claim-and-expiry flow and the MCP schema guardrails being the next pieces to firm up. Whether agent-created projects convert into paid ones is not something these entries show.

5.0

Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.

◆ Current state

Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.

◆ Where it's heading

The through-line across beta.4 to rc.1 is consolidation of the runner's architecture — one config resolution path, one Vite server, one project tree that can nest — paired with defaults that surface mistakes instead of tolerating them (strict toHaveTextContent, hoistable-scope errors, unawaited assertions failing). The browser mode is being narrowed to a single first-party stack rather than a plugin matrix. Performance work is now targeted at memory retention in vm pools and large --changed graphs, which reads as pre-GA cleanup rather than new capability.

◆ Prediction

With breaking changes still landing in rc.1, expect at least one more RC to settle the nested-projects and shared-server behaviour before a v5.0.0 final.
