pak 0.8.0

• pkg_deps() now accepts a vector of package names.

• The metadata cache now does not use source URLs for packages in Archive
  on Posit Package Manager repositories. This URLs may serve a different
  package, even a source package when the main URL for the same package
  serves a binary package. The alternative URLs are not needed on PPM,
  anyway, because PPM is in a consistent state w.r.t. metadata and
  package files (#623).

• pak now supports gitlab:: package sources better, by adding
  explicit syntax to specify subdirectories (r-lib/pkgdepends#353, @dgkf).

• gitlab:: and git:: package sources now support git submodules if
  the git-submodules configuration option is set to TRUE. See
  ?"pak-config" (r-lib/pkgdepends#354).

• The new ?ignore-unavailable parameter makes it easy to ignore soft
  dependencies that are unavailable (#606).

• pak now automatically ignores soft dependencies that have an
  incompatible OS type (OS_type entry in DESCRIPTION) when installing
  packages.

• repo_add() and the ppm_*() functions, e.g. ppm_snapshots(), now
  work again after the PPM API changes
  (r-lib/pkgcache#110,
  r-lib/pkgcache#115).
