pkgcache 2.2.4

• parse_packages() now parses files ending with an extra newline
  correctly (#122).

• pkgcache now supports authenticated repositories, see repo_auth()
  for details.

• ppm_has_binaries() now works correctly on all platforms (#121).

• The output of ppm_platforms() now has a new column called platform,
  which is a list column of character vectors, listing all possible
  matching platforms.

• pkgcache now detects the platform and R version of R Universe binaries.

pkgcache 2.2.3

• 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 (r-lib/pak#623).

• parse_packages() now does not throw a warning for empty PACKAGES*
  files (#107).

• repo_set() and the ppm_*() functions, e.g. ppm_snapshots(), now
  work again after the PPM API changes (#110, #115).

pkgcache 2.2.2

• pkgcache now treats R 4.5.x (current R-devel) macOS binaries
  correctly. It is also more robust to changes the in macOS platform.

pkgcache 2.2.1

• pkgcache now does a better job when matching the R version to a
  Bioconductor version.

pkgcache 2.2.0

• New pkg.current_platform option and PKG_CURRENT_PLATFORM environment
  variable to override the detected platform.

• 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.

pkgcache 2.1.1

• parse_installed() now has a packages argument, to list only a subset
  of all packages.

• parse_packages() can now parse PACKAGES files with trailing
  whitespace (#93).

• The Bioconductor repositories now include the 'books' repository,
  available since Bioconductor 3.12.

pkgcache 2.1.0

• pkgcache now supports binary packages on x86_64 macOS and R 4.3.0 and
  later (#89).

• Better Posit Package Manager (PPM) support. New ppm_has_binaries(),
  ppm_r_versions(), ppm_repo_url(), ppm_snapshots() and ppm_platforms()
  functions to help interacting with PPM. See the new 'pkgcache and Posit
  Package Manager on Linux' article at https://r-lib.github.io/pkgcache.
  (#47 and r-lib/pkgdepends#186).

pkgcache 2.0.4

• Update R version -> Bioconductor version mapping. R 4.2.x now maps to
  Bioconductor 3.16.

pkgcache 2.0.3

• The built and sysreqs columns of the metadata case are always
  character vectors now, and not logicals, as it used to be in some
  edges cases in the past.

• The deps column of the metadata cache is not a tibble any more,
  but a data frame with a tbl class, as it should be.

• cran_archive_*() functions now only download the metadata if it is newer
  than what you have currently.

• cran_archive_cleanup() now does not ignore the force argument.

• The sources column in the metadata cache now has the correct URL for
  packages in the CRAN archive (r-lib/pak#425).

pkgcache 2.0.2

• pkgcache error messages are better now.

• pkgcache now does not compress the metadata cache files, which makes
  loading the metadata cache faster.
