What is httr2?

httr2 is growing production concerns: tracing, throttling and token hygiene.

httr2 is the tidyverse's modern HTTP client and the designated successor to httr. Recent releases have moved past request-building ergonomics into operational concerns — OpenTelemetry traces for every request, throttling that behaves correctly across repeated calls, and a fix for OAuth token caches that were never actually being pruned.

What is RcppParallel?

RcppParallel rebuilt its TBB foundation in 6.0.0, then spent a week fixing what that broke.

Four releases landed in eight days. 6.0.0 bundles oneTBB 2022.0.0, stops re-exporting TBB headers through `RcppParallel/TBB.h`, and changes the TBB ABI so dependent packages need rebuilding; on Windows it switched to Rtools' TBB, restricting the TBB backend to R 4.2.0 and later. 6.1.0 adds `isProcessForkedChild()` in both R and C++ so packages can detect a forked process and fall back to serial work, and enables TBB by default on musl distributions like Alpine. 6.1.1 and 6.2.0 are installation repairs — cmake discovery on macOS, a C++20 iterator-dispatch bug in bundled oneTBB, and a return to shared TBB libraries on Windows.

2.5

httr2 is growing production concerns: tracing, throttling and token hygiene.

◆ Current state

httr2 is the tidyverse's modern HTTP client and the designated successor to httr. Recent releases have moved past request-building ergonomics into operational concerns — OpenTelemetry traces for every request, throttling that behaves correctly across repeated calls, and a fix for OAuth token caches that were never actually being pruned.

◆ Where it's heading

The package is maturing into infrastructure for long-running R services rather than interactive scripts. The 1.2.0 lifecycle purge removed deprecated streaming and mocking APIs in favour of a connection-based model, and debugging affordances like httr2_translate() point at users who need to reproduce a failing request outside R.

◆ Prediction

Expect further observability and credential-handling work, with the rlang-driven cache hash change in 1.3.0 likely to surface follow-up issues as existing caches silently invalidate.

R6.3

RcppParallel rebuilt its TBB foundation in 6.0.0, then spent a week fixing what that broke.

◆ Current state

Four releases landed in eight days. 6.0.0 bundles oneTBB 2022.0.0, stops re-exporting TBB headers through `RcppParallel/TBB.h`, and changes the TBB ABI so dependent packages need rebuilding; on Windows it switched to Rtools' TBB, restricting the TBB backend to R 4.2.0 and later. 6.1.0 adds `isProcessForkedChild()` in both R and C++ so packages can detect a forked process and fall back to serial work, and enables TBB by default on musl distributions like Alpine. 6.1.1 and 6.2.0 are installation repairs — cmake discovery on macOS, a C++20 iterator-dispatch bug in bundled oneTBB, and a return to shared TBB libraries on Windows.

◆ Where it's heading

The direction is toward RcppParallel owning its TBB, consistently, on every platform: 6.0.0 handed Windows to Rtools, and 6.2.0 reversed that to ship `tbb.dll` like everywhere else, explicitly so downstream packages have a library to link against and the ABI stops depending on the user's toolchain. Read together, the four releases are one migration and its aftermath. The fork-detection API is the other notable thread — it acknowledges that TBB and `mclapply()` do not mix.

◆ Prediction

Further installation and toolchain fixes are likely while the CRAN build farm exercises the new oneTBB on more configurations; the platform layout looks close to settled after 6.2.0.
