[dependabot]

Updates r-lib/actions from 2.11.4 to 2.12.0

Changelog

Sourced from r-lib/actions's changelog.

v2.12.0 (2026-04-29)

• All node.js actions use node 24 now. Relatedly, all example workflows use recent versions of actions that use node 24.

• [setup-r] now uses use-public-rspm: true by default on Linux and Windows. macOS binaries require further opt-in with use-public-rspm: always.

• It is now possible to require actions to be pinned to a full-length commit SHA in repositories using r-lib/actions (#1070).

• [setup-pandoc][setup-r-dependencies] now default to Pandoc version 3.8.3.

• [setup-r-dependencies] now includes the R architecture in the cache key, so caches for macos-15 (Apple Silicon) and macos-15-intel (Rosetta/x86_64) no longer collide (#1035).

• [setup-r] run apt-get update without -qq on Linux, to make debugging update failures easier (#1058).

v2.11.4 (2025-10-08)

• [setup-r] correctly installs Rtools again on aarch64 Windows, as needed.

v2.11.3 (2025-03-24)

• [setup-r] now supports Rtools45, and installs it by default for R >= 4.5.0.

v2.11.2 (2025-02-19)

• [setup-r] now installs gfortran 14.2 for R 4.5.0 and later (#965).

• [setup-r] now does not use PPM on aarch64 Linux, because PPM does not have binary packages for aarch64 Linux, and it would send x86_64 binarires for aarch64 systems as well.

• [setup-r] now unlinks pkg-config@0.29.2 on macOS silently, to avoid an error from the problem matchers (#973).

• [setup-r-dependencies] now supports dependencies: FALSE (@​eitsupi, #961).

• [setup-r-dependencies] now creates the R_LIBS_USER and R_LIBS_SITE library directories (#974).

• [setup-r-dependencies] now prints the R repo status (#975).
