pak 0.11.0

• 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.
