What is later?

later spends its releases keeping R's event loop compiling against moving toolchains.

later provides the event loop that lets R schedule callbacks, underpinning shiny, httpuv and most async work in the language. Recent releases are overwhelmingly build and compatibility work: Rcpp error-handling changes, a C23 namespace collision with glibc, and header ordering to satisfy Rcpp auto-includes.

What is Sanity?

Sanity ships across every package at once, and the agent-facing surface moves fastest.

Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.

later spends its releases keeping R's event loop compiling against moving toolchains.

◆ Current state

later provides the event loop that lets R schedule callbacks, underpinning shiny, httpuv and most async work in the language. Recent releases are overwhelmingly build and compatibility work: Rcpp error-handling changes, a C23 namespace collision with glibc, and header ordering to satisfy Rcpp auto-includes.

◆ Where it's heading

The API is settled enough that the release calendar is set by the surrounding ecosystem rather than by any feature plan. 1.4.5 cleaned house by dropping pre-unwind-protect fallbacks, and 1.4.6 carries the only recent change a user would notice at all — lower CPU use when idle at the console.

◆ Prediction

Expect further releases pinned to compiler and Rcpp changes, with the observable surface staying essentially where it is.

Sanity

7.5

Sanity ships across every package at once, and the agent-facing surface moves fastest.

◆ Current state

Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.

◆ Where it's heading

The MCP server is where the capability surface is actually growing — asset upload, schema discovery, CORS management — each release handing agents another operation that previously needed a human in the dashboard. The library work underneath is consolidation: one module system, one supported Node line, fewer dependencies, and now one SDK shared between Studio extensions and standalone apps. Read together, Sanity is narrowing the number of ways to build against it while widening what an agent can do unattended.

◆ Prediction

Expect the MCP tool list to keep absorbing dashboard operations — deploy, dataset and role management are the obvious remaining gaps — and the ESM-only floor to propagate to the packages that have not taken it yet. The releases are per-package, so a single dated entry rarely tells the whole story of a given week.
