Zarr's package split keeps producing standalone tools: a server, now a lazy indexer.

clock vs httr
A side-by-side editorial comparison of clock and httr — release velocity, themes, recent moves, and the top alternatives to consider.
clock vs httr: at a glance
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 httr?
httr's last releases are housekeeping - the package now points users at httr2
httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.

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.
httr

httr's last releases are housekeeping - the package now points users at httr2
◆ Current state
httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.
◆ Where it's heading
This is a succession, not a decline. The maintainers are keeping httr installable and passing checks for the very large base of packages that depend on it, while all design work happens in httr2. The pattern across these six releases is unambiguous: nothing lands here unless CRAN, a test service, or a platform forced it.
◆ Prediction
Expect continued patch releases driven only by CRAN checks and toolchain changes; the interesting HTTP work in R will keep landing in httr2.

promises drops R6 for plain environments and wires async work into OpenTelemetry
withr
withr rebuilt defer() on base R's own on.exit(), and got much faster for it
htmltools
htmltools spends three releases walking back its own fill-layout opinions
