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.

v2.0.1

No user visible changes.

v2.0.0

BREAKING CHANGE

• Starting from version 2.0.0 pkgcache returns data frames instead
  of tibbles. While data frames and tibbles are very similar, they are
  not completely compatible. To convert the output of pkgcache to tibbles
  call the as_tibble() function on them.

  pkgcache loads the pillar package at startup, if available, and uses it
  to improve the printing of pkgcache data frames.

OTHER CHANGES

• parse_packages() now automatically determines the type of the PACKAGES*
  file, instead of relying on file extensions.

• pkgcache can now call back again to a PACKAGES file if PACKAGES.gz is
  not available. (This fixes a regression in pkgcache 1.3.0.)

• pkgcache now uses HTTP 1.1 on Linux as well, because of crashes with
  HTTP/2.

• pkgcache now supports file:///, repositories, i.e. repositories on
  the local file system.

v1.3.0

• pkgcache now works better on M1 macs.

• current_r_platform() does a much better job now. In particular, on
  Linux it includes the name and release of the distribution.
  The new current_r_platform_data() function returns the platform information
  as a data frame, instead of a single string.

• Metadata is now more accurate for Windows packages that are typically
  not multi-arch any more on R 4.2.0 (current R-devel).

• pkgcache has its own DCF metadata parser now, which is much faster, and
  it parses all fields of PACAKGES* and DESCRIPTION files.

• New parse_installed() function to get the metadata of all installed
  packages in a library. It uses the new DCF parser, so it is quite fast.

• meta_cache_list() and related functions now correctly set the
  rversion column of source R packages to "*".

• pkgcache now users HTTP 1.1 on macOS, to work around a possible
  slowdown issue with libcurl for HTTP/2.

• pkgcache now uses our extra metadata (file sizes, system requirements,
  etc.) for RStudio Package Manager (RSPM) repositories as well, as long
  as they are named RSPM in getOption("repos").

v1.2.2

• The default location of the cache has changed to align with the
  standard tools::R_user_dir() cache location. To clean up your old
  cache call pkgcache:::cleanup_old_cache_dir().

v1.2.1

No user visible changes.

v1.2.0

• New repo_add(), repo_get(), repo_resolve() and with_repo()
  functions to query and manipulate repositories.

• meta_cache_*() functions now handle getOption("repos") changes
  correctly.

• Failed metadata downloads now do not trigger metadata updates (#52).

• New bioc_release_version(), bioc_devel_version(), bioc_repos()
  helper functions to deal with Bioconductor repositories.

• Metadata cache functions, e.g. meta_cache_deps() etc. now allow
  specifying the dependency types in all lowercase (#54).

v1.1.1

• package_cache now does not fail if the web server does not send an
  Etag header when downloading packages.

• package_cache has now much relaxed HTTP timeouts, and handles
  downloading many packages (slowly) much better.

• The package download progress bar can now be supressed by setting
  the pkg.show_progress option to FALSE.

v1.1.0

• New repo_status() function to query the status and response time
  of CRAN-like repositories.

• New bioc_version() and bioc_version_map() functions to query
  Bioconductor repositories.

• pkgcache now does not fail if some repositories do not provide
  some package types.

• New current_r_platform(), default_cran_mirror() and
  default_platforms() functions.

• pkgcache now works for R 4.0.x macOS binaries.

v1.0.7

• Metadata is now cached in RDS version 2 formats, so metadata written
  by newer R version can be used by older R versions as well (#36).
