Note that v2 is a sliding tag, and we introduce non-breaking changes to it.

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 [email protected] 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).

• Example workflows that use renv now call setup-r with
  r-version: renv, to install the R version declared in the
  renv.lock file.

v2.11.1 (2024-11-25)

• [setup-r] now unlinks the pre-installed pkg-config brew package
  to fix a clash with the new pkgconf package (#948).

v2.11.0 (2024-11-09)

• [setup-r-dependencies] parameter pak-version can now be repo or
  none as well. repo means that the action will install pak from
  the configured repositories, using install.packages(). repo is
  appropriate on systems that do not have access to our pak reporitory
  on GitHUb. none means that the action does not install pak at all.
  Use this if you want to install pak yourself manually. Set the
  R_LIB_FOR_PAK environment variable to point to the library where pak
  is installed.

• [setup-r] now has a working-directory parameter, to be able to
  specify the location of the renv.lock file (#922, @calderonsamuel).

• Example check-like workflows now run on all pull requests, not only
  on pull requests against the main branch.

• [setup-r-dependencies] and [setup-renv] now do not use the
  deprecated save-always parameter of actions/cache.

• [setup-renv] now correctly accepts bypass-cache: never, as stated
  in the documentation.

• [setup-r-dependencies] now saves the package cache correctly on
  Windows with older R (#940).

v2.10.1 (2024-08-08)

• [setup-r-dependencies] now pins quarto-dev/quarto-actions/setup
  version to a constant sha, to be compatible with organizations where
  this is a requirement (#901).

• [setup-renv] now also caches R packages in renv/library, used when
  RENV_CONFIG_PAK_ENABLED: true (#900).

• [setup-manifest]: new action to set up an R project with a Posit
  Connect manifest.json file (#880).

v2.10.0 (2024-08-02)

• [setup-r]: on R 3.6.x we now use the P3M snapshot from 2024-06-01 by
  default. This is because many newer CRAN packages do not work on R 3.6.x
  any more. The default CRAN mirror is still added, so newer packages may
  be used if they are required, but setup-r-dependencies@v2 will prefer
  the binary packages from P3M.

  Note that this only happens if you opt in to use P3M with the
  use-public-rspm: true input parameter. This is the default in all
  example workflows.

  If the RSPM environment variable is already set, then it is used
  unchanged, on all R versions. To avoid using a P3M snapshot on R 3.6.x,
  set the RSPM_PIN_3_6 environment variable to false.

• [setup-r] now installs the x86_64 build of R on arm64 macOS, if there
  is no arm64 build available for this R version (#883).

• Example blogdown, bookdown, document, pr-commands and render-markdown
  workflows now correctly have write permission to repository contents
  (#874, @remlapmot).

• [check-r-package]: you can now setupload-snapshots to always, to
  upload snapshots even after failures (#871).

• [setup-r-dependencies] now always sets the R_LIBS_USER GitHub
  environment variable, so it can be used without [setup-r] or without
  setting it manually (#881).

• The example workflows now use their file names as workflow names.
  This is to make it easier to match worflow runs to workflow files.
  Most of the the check-* workflows use R-CMD-check.yaml, however,
  to anticipate the usethis package renaming them by default (#888).

• [setup-renv]: you can now set bypass-cache to never, to save the
  cache even if the workflow fails (#873, @jaradkohl-mfj).

• [setup-pandoc]: installing nightly Pandoc works again now (#889).

• [setup-r-dependencies] now automatically installs Quarto if the repo
  has a qmd file, and it isn't installed. See the install-quarto and
  quarto-version input parameters (#866).

• [setup-r] now avoids spurious warnings from Homebrew (#864).

• [setup-r-dependencies] now accepts pak-version: none to skip pak
  installation. pak should be already installed on the system in this
  case, otherwise the dependencies resolution and installation will fail.
  You probably also need to set the R_LIB_FOR_PAK env var to the library
  where it is installed.

v2.9.0 (2024-05-09)

• The test-coverage.yaml example workflow now handles global Codecov
  tokens for test coverage uploads to codecov.io
  (@ALanguillaume, @gaborcsardi, #823).

• The check-full.yaml example does not test on R 3.6.x any more.

• All example workflows set the default permissions now to read-only.

• We deleted the (long broken) run-rchk action.
  R-hub will have an rchk container and builder soon: r-hub/containers#29.

• [setup-r-dependencies]: new option to save the R package cache for
  unsuccessful workflow runs as well (@schloerke, #695).

• New example workflows bookdown-gh-pages and blogdown-gh-pages to
  deploy bookdown books and blogdown sites to GH Pages without commiting
  them into the repository (#856).

v2.8.7 (2024-04-05)

• [setup-r-dependencies] now has a lockfile-create-lib input parameter, that is
  passed to pak::lockfile_create(lib = ...) (#814).

v2.8.6 (2024-03-30)

• [setup-r] now does not install qpdf on Windows, because it is part of all Rtools
  versions that we use. Also, it installs Ghostscript from a .zip file instead of a
  choco package, because choco install can sometimes freeze (#812).

v2.8.5 (2024-03-26)

• [setup-r] uses a different tag name to download system packages from on
  Windows. This is to fix r-lib/usethis#1967.

v2.8.4 (2024-03-25)

• [setup-r]: Ghostscript and QPDF installation is now more robust on Windows.
  We download and install manually, instead of installing from the Chocolatey
  repository (#812).

v2.8.3 (2024-03-20)

• [setup-r] now sets the HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK=true
  environment variable when installation associated tools on macOS. Without this brew
  often fails on outdated Homebrew installations (#810).
• [setup-r-dependencies] now works on aarch64 Linux.

v2.8.2 (2024-03-18)

• [setup-r] now supports Rtools44, and installs Rtools44 for R 4.4.x (currently R-devel).
• [check-r-package] now supports upload-results: never to never upload
  check results as artifacts. This is useful if you want to handle artifact uploads
  yourself.

v2.8.1 (2024-02-29)

• [setup-r-dependencies]: fix Pandoc auto-installation (#808).

v2.8.0 (2024-02-27)

• [setup-r] now allows rtools-version: none to skip installing Rtools (#767).
• [setup-pandoc]: The default version is 3.1.11 now.
• [setup-pandoc] can now install the latest pandoc version, or the pandoc nightly build.
• [setup-pandoc] now supports arm64 macOS and any amd64 or arm64 Linux distribution.
• [setup-r-dependencies] now installs pandoc if the R package depends on the rmarkdown package.
• [check-r-package] now has inputs artifact-name and snapshot-artifact-name to specify artifact names explicitly (#800).
• The styler example now sets permissions correctly (#775, @thisisnic).
• The test coverage example now handles paths with spaces or special characters (#782, @Felixmil).
• The check example workflows now use a better build_args parameter (#787).

v2.7.2 (2024-02-01)

• [check-r-package] now uses better artifact names. It includes matrix.config.id from the job matrix in the artifact name. If that's not defined then the zero-based job index in the matrix is used. For non-matrix jobs, this is 0.

v2.7.1 (2024-01-31)

• [check-r-package] now includes the runner architecture in the name of the test output artifact, to avoid a name clash between macos-14 and other macOS runners.

v2.7.0 (2024-01-31)

• [setup-r] now removes Homebrew R from the PATH on macOS. With this setup-r works on the new arm64 macos-14 platform.
• All actions and examples now use Node 20 actions.

v2.6.5 (2023-10-27)

• [setup-r] now tries to avoid *.r-project.org URLs, to work around a DNS issue.
• [check-r-package] now only sets _R_CHECK_CRAN_INCOMING_=false if it is not set already (@krlmlr, #764).
• [setup-renv] now has a working-directory parameter (@milanmlft, #770).
• The example test-coverage.yaml workflow now works on Windows.

v2.6.4 (2023-07-14)

• [setup-r-dependencies] now works without sudo on Linux.
• [setup-renv] now only installs renv if not installed already, e.g. the installation of the correct renv version
  is typically triggered from the .Rprofile (#747).

v2.6.3 (2023-04-26)

• [setup-r] now installs gfortran 12.2 only for R 4.3.0 and newer, as it is not compatible with the
  R 4.1.x (and possibly other) R builds (#722).

v2.6.2 (2023-04-24)

• [setup-r] sets its installed-r-version output correctly again, to the actual R version number.
• [setup-r] now installs gfortran 12.2 for R 4.0.0 and newer. This fixes fortran compilation for
  R 4.3.0 and newer.

v2.6.1 (2023-04-21)

• [setup-r] observes the rtools-version input parameter again (#720).
• The pkgdown example now sets the permissions of the automatic GITHUB_TOKEN
  to allow deployment (#719, @jennybc).

v2.6.0 (2023-04-21)

• [setup-r] now does a better job resolving R version specifications.
• The example workflow for styler now commits all styled files (#693, @dpprdan).

v2.5.0 (2023-04-01)

• [setup-r]: better cache key for R-devel: now the graphics engine API id and t he internal R id are also included
  in the cache key (#699, @schloerke).
• [setup-r]: the r-version parameter can now be set to renv, to read the R version to install from the
  renv.lock file (#701, @iqis).
• [setup-r]: now installs Rtools43 for R 4.3.0 (current R-next) and later (#714).
• [setup-r-dependencies]: new input parameter: upgrade, whether to install the latest available package
  versions. Defaults to FALSE.
• [setup-tinytex]: handle tinytex 2023 change about windows directory (#712, @cderv).
• [setup-pandoc]: fix installation of Pandoc 3.1.2 (and possibly later) on macOS (#716, @IndrajeetPatil).
• The example document.yaml workflow now also saves the DESCRIPTION file (#694, @dpprdan).

v2.4.0 (2023-01-16)

• [setup-r]: supports Rtools43 now. On R-devel Windows Rtools43 is installed by default (#682).

v2.2.8 (2022-08-31)

• Examples now use ubuntu-latest instead of ubuntu-20.04. This avoid having to update your workflows every two years.
  It does not change anything right now, however, as ubuntu-latest is the same as ubuntu-20.04 currently.

v2.2.7 (2022-08-23)

• HTML 5 check example now works for packages with vignettes (by ignoring them), #611.
• [setup-r] now adds Rtools40 to the PATH for Windows ucrt R versions, so R can compile packages again, #610.

v2.2.6 (2022-08-22)

• Examples now use Ubuntu 22.04, because 18.04 is deprecated on GHA.

v2.2.1 (2022-04-21)

• [setup-r] release is now fixed to R 4.1.3 on Linux, until we have the Linux binaries and RSPM binary packages
  ready for R 4.2.0.

v2.2.0 (2022-04-01)

• [setup-r] now supports next as an R version. It installs the next version of R. This is R-patched if there is no
  active release process. Otherwise it can be R-alpha, R-beta, R-rc or R-prerelease (#542).
• [setup-r-dependencies] has a new cache input parameter, which you can set to false to disable the cache
  (@Bisaloo, #530).
• [setup-r-dependencies] now removed the temporary .github/pkg.lock file after the package installation,
  to avoid a dirty git tree (@schloerke, #526).

v2.1.3 (2022-02-18)

• [setup-r-dependencies]: the pak-version parameter defaults to "stable" now.
• [setup-tinynex] now fails if it fails to download or install TinyTeX (#505).

v2.1.2 (2022-02-16)

• [setup-r] now again adds Rtools40 to the path (#504, @nealrichardson).
• [setup-r] Rtools42 version updated to latest.

v2.1.1 (2022-02-14)

• [setup-r-dependencies] uses the correct cache key now, previously it was truncated.

v2.1.0 (2022-02-12)

• [setup-r-dependencies] now has a packages parameter, to override which package(s) to install (#486).
• [setup-r] now supports Rtools42. Pass '42' as the rtools-version parameter (#491).
• [setup-r]: the windows-path-include-mingw parameter is now defunct with Rtools40 and later, as it is not needed and possibly causes confusion.
• [check-r-package] has a new parameter: upload-snapshots, to upload testthat snapshots as artifacts (#473).
• The pkgdown, bookdown and blogdown examples now use concurrency groups to avoid race conditions when deploying the site (#476).
• The test-coverage example now keeps the output from covr, to make debugging easier (#481).
• Two new examples are included, to run roxygen2::roxygenise() and styler::style_pkg() on a repo and commit the results (#434).

v2.0.11 (2022-01-16)

• [setup-r] forces HTTP/1.1 for pak/pkgcache.
• [setup-r-dependencies] does the same. This seems to fix crashes during package installation (#483).

v2.0.10 (2022-01-11)

• The pkgdown example now uses clean: false to allow a production and a dev site.

v2.0.9 (2022-01-11)

• [setup-r] now does not download qpdf on Windows, because it is already
  included in Rtools (#474).

v2.0.8 (2022-01-11)

• [check-r-package] does not print the environment now, because there is a slight chance that printing
  exposes processed secrets that GitHub's reduction mechanism misses.

v2.0.7 (2022-01-06)

• Simplified GitHub Pages deployment in the pkgdown example (#468).

v2.0.6 (2022-01-05)

• [setup-r] does not add the ppa:cran/travis PPA on Ubuntu, as it is not needed any more. (@jeroen, #465)
• [setup-r] macOS R-devel builds use a more robust R download URL now (@s-u, #466).
• [setup-r-dependencies] now uses the correct cache key if working-directory is specified (@harupy, #471)

v2.0.5 (2021-12-17)

• [setup-r-dependencies] now works with older versions of the sessioninfo package.
  (This typically happens on older R versions and Windows or macOS, where pak prefers
  to install an older binary package to a newer source package, unless the newer package
  is needed.)

v2.0.4 (2021-12-16)

• [setup-r] and [setup-r-dependencies] now have better organized output
• [check-r-package] now prints all environment variables before the check.

v2.0.3 (2021-12-15)

  and it is equivalent to devel.

v2.0.2 (2021-12-14)

• [check-r-package] now sets the _R_CHECK_FORCE_SUGGESTS_=false environment variable,
  unless it was already set before to a non-empty value.

v2.0.1 (2021-12-13)

• [setup-r-dependencies] is now better at ignoring soft package dependencies that
  cannot be installed on the current R version. See more in the README here:
  https://github.com/r-lib/actions/tree/v2/setup-r-dependencies#ignoring-optional-dependencies-that-need-a-newer-r-version

v2.0.0 (2021-12-12)

Breaking changes from v1

• [check-r-package]: many parameters have a new format now, and they need
  to be legal R expressions.
• [setup-r] does not have a crayon.enabled parameter now. You can update
  .Rprofile manually to set options if you like, see example in the README.

New compared to v1

• [check-r-package] has a working-direcytory parameter now (#393).
• [check-r-package] prints the testthat output, and uploads artifacts on failure
  now, no need to do these in the workflow file.
• [run-rchk] is now a more flexible composite action (@randy3k, #380, #428).
• [setup-pandoc] now defaults to Pandoc version 2.14.2.
• [setup-r] more robust installation in macOS, hopefully the hangs are solved.
• [setup-r] now works on macOS Big Sur for older R versions (#412).
• [setup-r-dependencies] has more robust dependency and system dependency lookup
  and installation (#370, #386, #405, #419, #430, #431, #432, #437).
• [setup-r-dependencies] automatically uses the UCRT versions of packages on UCRT R.
• [setup-r-dependencies] has a working-directory parameter now (#393, #438).
• [setup-r-dependencies] has a less conservative cache key now for R-devel (#429).

  dependencies are installed (#409).

Changes in example workflows from v1

• New example workflows, that work with the v2 tag.
• Example pkgdown workflow builds releases now (#450).
• bookdown, blogdown and pkgdown examples now have workflow triggers to
  trigger a build manually.
• bookdown, blogdown and pkgdown examples now build on pull requests as
  well, without deploying (#363).
• Check examples omit showing the testtat output and the artifact upload
  on error, these are done in the check-r-package action now.
