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

`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).
