What is clock?

clock is turning calendar conventions lubridate hard-coded into parameterized types.

clock provides typed date-time handling for R on top of the C++20 date library, with explicit calendar and time-point types instead of implicit coercion. The visible history splits between genuine arithmetic additions and a long tail of compiler and CRAN-policy repairs. Recent releases are mostly the latter, with 0.7.3 raising the tzdb and R floors.

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.

0.0

clock is turning calendar conventions lubridate hard-coded into parameterized types.

◆ Current state

clock provides typed date-time handling for R on top of the C++20 date library, with explicit calendar and time-point types instead of implicit coercion. The visible history splits between genuine arithmetic additions and a long tail of compiler and CRAN-policy repairs. Recent releases are mostly the latter, with 0.7.3 raising the tzdb and R floors.

◆ Where it's heading

The feature arc moves toward making conventions explicit and parameterized rather than fixed: counting units between dates in 0.6.0, duration modulus and integer division alongside it, then a week-start-parameterized calendar in 0.7.0 that subsumes both ISO and CDC epidemiological weeks. Since 0.7.0 the package has added almost no surface, spending releases on C++ toolchain compliance instead. The 0.7.3 parsing change, following upstream to character-width rather than digit-count parsing, is the one recent break users must handle.

◆ Prediction

The last three releases are maintenance-shaped, so the next most likely tracks another tzdb or compiler requirement rather than adding calendars.

Sanity
DEVOPS
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.
