What is Sanity?

Sanity is paying down its runtime weight while wiring agents into the content layer.

Two lines of work run in parallel across this window. The platform layer is shedding weight and legacy: @sanity/ui v4.0.0 goes ESM-only, moves heavy components behind subpath imports, and requires a stylesheet import, while the Media Library asset grid switches to viewport-only rendering. The agent layer is filling out fast — two MCP server releases in under a week add CLI execution, explicit release IDs, and transactional document patching, and the React App SDK gains bidirectional presence that interoperates with Studio.

What is Z-Wave JS?

Z-Wave driver where the hard problems are now smart locks and device quirks.

Z-Wave JS is the driver layer underneath most open-source Z-Wave integrations, and its releases follow a tight weekly-to-fortnightly rhythm mixing three things: protocol correctness, device config files, and developer surface. The current focus is clearly credential handling on smart locks — several consecutive releases fix stale cached credentials, bulk user deletion timeouts, and locks misreporting progress during credential learning. Alongside that, inclusion reliability got direct attention, with ongoing interviews now paused during inclusion and security bootstrapping.

Sanity is paying down its runtime weight while wiring agents into the content layer.

◆ Current state

Two lines of work run in parallel across this window. The platform layer is shedding weight and legacy: @sanity/ui v4.0.0 goes ESM-only, moves heavy components behind subpath imports, and requires a stylesheet import, while the Media Library asset grid switches to viewport-only rendering. The agent layer is filling out fast — two MCP server releases in under a week add CLI execution, explicit release IDs, and transactional document patching, and the React App SDK gains bidirectional presence that interoperates with Studio.

◆ Where it's heading

The MCP server is being hardened into a supervised write path rather than a read-only convenience: patches roll back as a unit, malformed IDs are rejected up front, and schema deploys now refuse to touch a Studio-managed workspace even when stale state says otherwise. That last rule is the direction in miniature — agents are being given real write access, fenced off by workspace ownership. Meanwhile the frontend packages are absorbing a breaking release to make bundle size a property of what you import rather than what ships.

◆ Prediction

The v4.0.0 notes state that more components move off runtime CSS-in-JS across the 4.x minors, so the bundle work continues incrementally rather than in another breaking jump. On the SDK side the presence release explicitly defers rendered remote selections to a forthcoming Portable Text plugin — the most concretely signposted next item in the feed.

5.0

Z-Wave driver where the hard problems are now smart locks and device quirks.

◆ Current state

Z-Wave JS is the driver layer underneath most open-source Z-Wave integrations, and its releases follow a tight weekly-to-fortnightly rhythm mixing three things: protocol correctness, device config files, and developer surface. The current focus is clearly credential handling on smart locks — several consecutive releases fix stale cached credentials, bulk user deletion timeouts, and locks misreporting progress during credential learning. Alongside that, inclusion reliability got direct attention, with ongoing interviews now paused during inclusion and security bootstrapping.

◆ Where it's heading

The protocol work is moving from getting commands through to getting them right under adversarial timing — S2 delivery verification, split multi-frame reports, and optimistic value updates now distinguishing actuator from non-actuator command classes. The other steady stream is the device database, which absorbs manufacturer inconsistencies so integrations above it do not have to.

◆ Prediction

User Code and User Credential handling should keep generating fixes, since each release surfaces another lock firmware that deviates from the spec in a new way.
