Log Message:
(devel/R-pak) Updated 0.5.1 to 0.7.1

# pak 0.7.1

* pak can now handle the case when `Config/Needs/*` dependencies
  are requested for package from a repository.

* pak uses safer `*printf()` format strings now.

# pak 0.7.0

* pak now correctly handles the latest GitHub release with
  the `@*release` notation (@pawelru,
  https://github.com/r-lib/pkgdepends/pull/321)

* pak now correctly handles having multiple instances of the same
  package in the metadata, with different R version requirements
  (#534, #538, https://github.com/r-lib/pkgdepends/pull/331).

* `git::` package references work better now for Azure DevOps
  (@jameslairdsmith, https://github.com/r-lib/pkgdepends/pull/333,
  https://github.com/r-lib/pkgdepends/pull/342).

* pak now does a better job at accepting installed packages, and
  avoids reinstalling more packages than needed when using a lock file
  (https://github.com/r-lib/actions/issues/759,
  https://github.com/r-lib/pkgdepends/pull/338).

# pak 0.6.0

* pak now requires R >= 3.5.0.

* Many improvements in system requirements support:
  - New functions:
    - `pkg_sysreqs()`: calculate system requirements of packages.
    - `sysreqs_db_list()`, `sysreqs_db_match()`, `sysreqs_db_update()`:
      query the system requirements database.
    - `sysreqs_list_system_packages()`, `sysreqs_check_installed()`,
      `sysreqs_fix_installed()`: query and install missing system packages.
    - `sysreqs_platforms()`: list supported platforms.
  - The installation proposal, printed before installation, now includes
    required and missing system packages, on supported platforms.
  - New `sysreqs_platform` configuration option to override the auto-detected
    platform.
  - Faster, asynchronous system requirements lookup.
  - pak now does not reinstall system requirements by default,
    if they are already installed. (You can force a reinstall/upgrade
    with the `sysreqs_update` configuration option.)

* New `gitlab::` package source to install packages from GitLab
  (https://github.com/r-lib/pkgdepends/pull/315).

* pak now correctly parses multiple `git::` packages at once
  (https://github.com/r-lib/pkgdepends/issues/318).

* `git::` package sources now support version 1 of the git protocol.
  E.g. the Bioconductor git repositories now work:
  `git::https://git.bioconductor.org/packages/limma`
  (https://github.com/r-lib/pkgdepends/issues/314).

* The `platforms` config parameter now works correctly with `deps::`
  package sources (#522).

* New `include_linkingto` config parameter to always include `LinkingTo`
  packages in the solution, even for binaries
  (https://github.com/r-lib/pkgdepends/issues/485).

* `pkg_name_check()` now does not include Acromine results, because the web
  site was unstable.

* In `repo_add()` and `repo_resolve()` the `MRAN@` prefix is now deprecated
  and resolves to PPM, because MRAN will be retired soon. See more at
  <https://posit.co/blog/migrating-from-mran-to-posit-package-manager/>.

* The metadata cache now has `SystemRequirements` information for Bioconductor
  packages.
