• pak now supports the configure_args and configure_vars configuration
  options. They default to the configure.args and configure.vars
  options, for compatibility with install.packages() (#788).

• GitHub remotes now auto-detect an R package in a well-known subdirectory
  (pkg-r/, r/, or R/) when no subdir is given and there is no
  DESCRIPTION at the repository root. This lets multi-language
  repositories be installed without specifying subdir (#459).

• pak now handles the case when a repository (typically Posit Package
  Manager) serves a source package instead of the requested binary (#891).

• Better error messages for several dependency solver situations:

  • when requesting a package that is installed locally, but was removed
    from its repository (#895),
  • when requesting an older version (e.g. pkg@1.0.0) of a package that
    is no longer in the repository (#896),
  • when resolving downloads for a different platform
    (r-lib/pkgdepends#462).

• The dependency solver no longer silently keeps an installed package as
  the solution for a direct package reference that failed to resolve, e.g.
  a CRAN package that is not on CRAN but happens to be installed locally
  from another source. pak now reports the failure instead.

• install_args is no longer overwritten when building packages. The
  --no-multiarch flag needed on some Windows configurations is now added
  to the existing install_args
  (r-lib/pkgdepends#472).

• Duplicate system requirement commands are now deduplicated (#888).

• pak now behaves better when the package cache database is corrupt: it
  gives a better error message, and cleaning the cache no longer fails in
  this case (#884).

• pak now handles PACKAGES files with Path and/or File fields
  correctly, and drops HTTP query parameters from these fields when
  constructing the target file name
  (r-lib/pkgcache#141, @jeroen).

• All HTTP requests now honor the pkgcache_http_version option and the
  PKGCACHE_HTTP_VERSION environment variable
  (r-lib/pkgcache#140).

• pak now retries failed HTTP requests by default, using an exponential
  backoff (and honoring the Retry-After header). Set the PKG_HTTP_RETRY
  environment variable or the pkg_http_retry option to FALSE to disable
  retries.

• pak now supports Posit Package Manager's Sigle Sign-On authentication.

• Vector valued library path now works correctly in lockfile_create()
  (#864, #868).

• pak now handles better PPM binaries on private PPM instances (#863).

• pak now works again with custom HTTPS certificates (#647, @tl-hbk).

• Setting use_bioconductor = FALSE (i.e. the PKG_USE_BIOCONDUCTOR
  env var, or the pkg.use_bioconductor option) now truly prevents
  any network contact with Bioconductor.

• pak now supports macOS binaries on R 4.6.x and later.

• pak can now consider installed packages in mutliple
  libraries, when installing packages. Pass a character vector
  of library path as the lib argument of pkg_install().

• No user visible changes.

• pak is now more tolerant with extraneous whitespace in PACKAGES*
  metadata files (#785).

• pak now builds again on FreeBSD (#790).

• Installing dependencies of a package file with deps::<filename>
  works again (#784).

• pak now always uses the correct working directory in the subprocess;
  this was a common source of errors.

• New (nightly) binary builds for aarch64 Windows.

• We do not build binary builds for the release candidate of pak any
  more, only for stable and devel pak. rc is an alias to stable now.

• pak now supports HTTP basic authentication for CRAN-like repositories.
  See 'Authenticated repositories' in the reference manual.

• New function scan_deps() to auto-detect package dependencies from
  R code. deps::. automatically uses detected dependencies now if no
  DESCRIPTION file is found.

• The dependency solver now uses better heuristics, that works better
  (=faster) with multiple repositories with large overlaps
  (r-lib/pkgdepends#392).

• pak is now much better at detecting the correct Linux distribution
  when deciding about PPM and system requirements support.

• pak now uses the use_bioconductor configuration option in meta_*() and
  repo_*() functions (#295, #726, @meztez).
