pkgbuild vs Rhino: at a glance
What is pkgbuild?
A package whose release calendar is written by whoever ships the next Rtools.
pkgbuild is the layer devtools and pak use to run R CMD build and R CMD INSTALL, and most of what it does is know where the compiler is. Six of its last eight releases are about Rtools: supporting Rtools43, 44 and 45, finding installations that did not come from an installer, reading the Windows registry correctly again, and handling aarch64 Windows when the expected environment variable is unset. The feature surface is a handful of Config/build/* DESCRIPTION options for packages with unusual build needs.
What is Rhino?
Rhino's release line runs on release candidates, and 1.12 makes room for coding agents.
Rhino publishes only release candidates to this feed — every entry back to 1.9 is an -rc tag, with no final release ever appearing. The 1.12.0 candidate is the first in the window with user-visible substance: a `use` function that scaffolds an AGENTS.md file carrying Rhino-specific instructions, plus a `use` function for the CI template. The rest is maintenance: covr-based test coverage, e2e tests, Node dependency updates, and a maintainer handover.

◆ Current state
pkgbuild is the layer devtools and pak use to run R CMD build and R CMD INSTALL, and most of what it does is know where the compiler is. Six of its last eight releases are about Rtools: supporting Rtools43, 44 and 45, finding installations that did not come from an installer, reading the Windows registry correctly again, and handling aarch64 Windows when the expected environment variable is unset. The feature surface is a handful of Config/build/* DESCRIPTION options for packages with unusual build needs.
◆ Where it's heading
This is maintenance defined entirely by other people's release schedules — R minor versions, Rtools versions, and the DESCRIPTION options downstream package authors ask for. The one structural change worth noting is that on R 4.3 and later the package stopped special-casing Windows and now tests for build tools by compiling a small package, the same way it always has on Unix. That is the direction: fewer platform branches, more probing.
◆ Prediction
Expect the next release to add support for whichever Rtools ships alongside the next R minor version, and expect the Windows registry lookups to keep shrinking as the compile-probe approach proves out.
Rhino
0.0INFRA · APIS
Rhino's release line runs on release candidates, and 1.12 makes room for coding agents.
◆ Current state
Rhino publishes only release candidates to this feed — every entry back to 1.9 is an -rc tag, with no final release ever appearing. The 1.12.0 candidate is the first in the window with user-visible substance: a `use` function that scaffolds an AGENTS.md file carrying Rhino-specific instructions, plus a `use` function for the CI template. The rest is maintenance: covr-based test coverage, e2e tests, Node dependency updates, and a maintainer handover.
◆ Where it's heading
Rhino is converging on scaffolding as its main surface — the framework's value is increasingly in what it generates for you rather than what it does at runtime, and 1.12 extends that generation to instructions meant for AI coding agents rather than humans. The maintainer change and the CI/coverage work in the same release read as consolidation after a long gap: 1.11 shipped in April 2025, 1.12 not until June 2026.
◆ Prediction
More `use_*` scaffolding functions are the obvious next increment, since two arrived in a single release. Whether the AGENTS.md instructions grow into deeper agent tooling is not something these entries settle.
