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

• pkgdepends now does not restore ownership when uncompressing.tar.gz
  files. This works better on sshfs and other file systems that do not
  have proper Unix permissions.

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

• pkgdepends now supportsgitlab:: package sources better, by adding
  explicit syntax to specify subdirectories (#353,@dgkf).

• gitlab:: andgit:: package sources now support git submodules if
  thegit-submodules configuration option is set toTRUE. See
  ?"pkgdepends-config" (#354).

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

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

Contributors

• pkgdepends now supports the* wildcard for parameter specifications,
  for paramrters applied to all packages. E.g.*=?source means
  compiling all packages from source.

• pkgdepends now does not import the glue, rprojroot and prettyunits
  packages.

• pkgdepends can now handle the case whenConfig/Needs/* dependencies
  are requested for package from a repository.

• pkgdepends now correctly supports the@*release suffix for GitHub
  repositories (#275,@pawelru).

• pkgdepends now correctly handles having multiple instances of the same
  package in the metadata, with different R version requirements
  (r-lib/pak#534,#331,
  r-lib/pak#538).

• git:: package references work better now for Azure DevOps
  (@jameslairdsmith,#333,#342).

• pkgdepends now correctly resolves the latest GitHub release with
  the@*release notation (@pawelru,#321).

• pkgdepends now does a better job at accepting installed packages, and
  avoids reinstalling more packages than needed when using a lock file
  (r-lib/actions#759,#338).

Contributors

• Many system requirements improvements:

  • New sysreqs functions:
    • sysreqs_check_installed(): check if all required system packages
      are installed,
    • sysreqs_fix_installed(): install missing system packages,
    • sysreqs_db_list(): list system requirements database,
    • sysreqs_db_match(): matchSystemRrequirements field(s) to database,
    • sysreqs_db_update(): update system requirements database,
    • sysreqs_install_plan(): look up system requirements for a package and
      its dependencies,
    • sysreqs_is_supported(): check if pkgdepends supports system
      requirements on your platform,
    • sysreqs_list_system_packages(): list installed system packages,
    • sysreqs_platforms(): list supported platforms.
    • Newpkg_installation_proposal methods:get_sysreqs(),show_sysreqs()
      andupdate_sysreqs().
  • The output of$show_solution() now includes system requirements.
  • Newsysreqs_platform configuration option.
  • pkgdepends now looks up system requirements asynchronously, during
    dependency resolution.
  • pkgdepends now does not reinstall system requirements by default,
    if they are already installed. (You can force a reinstallation/upgrade
    wtih thesysreqs_update configuration option.)

• Newgitlab:: package source to install packages from GitLab (#315).

• pkgdepends now correctly parses multiplegit:: packages at once (#318).

• git:: package sources now support version 1 of the git protocol.
  E.g. the Bioconductor git repositories now work:
  git::https://git.bioconductor.org/packages/limma (#314).

• Theplatforms config parameter now works correctly withdeps::
  package sources (r-lib/pak#522).

• Newinclude_linkingto config parameter to always includeLinkingTo
  packages in the solution, even for binaries (#485).

• pkg_name_check() now does not include Acromine results, because the web
  site was unstable.

• pkgdepends now support git repositories as package references. E.g.
  git::https://github.com/r-lib/pak.git.

• pkgdepends now supports versioned CRAN packages, e.g.dplyr@1.1.1 will
  always install dplyr 1.1.1. Note that only CRAN packages are supported,
  Bioconductor packages are not (yet).

• pkgdepends now has an alternative system requirements lookup
  implementation. It supports Fedora and Debian systems as well, in
  addition to Debian, Ubuntu, SUSE and RedHat derivatives.
  You can switch to this implementation by setting the
  R_PKG_SYSREQS2 environment variable totrue.

• pkgdepends now does a better job looking up dependencies for
  hand-selected dependency types. E.g.dependencies = "LinkingTo".

• pkgdepends now removes?ignore-d packages from dependencies, and
  uses the correct version comparison for?ignore-before.r
  (r-lib/actions#708).

• pkgdepends now does not fail for circular soft dependencies (#306).

• pkgdepends now reports dependency solver failures better in some cases
  (#305,r-lib/pak#474).

• pkgdepends now uses locally built CRAN binaries from the cache.

• pkgdepends has much improved and more informative error messages now.
  This work is not yet finished, so if you find an unclear error message,
  please open an issue. Thank you!

• The solver is now more robust for non-canonical input (e.g.DESCRIPTION
  files) (r-lib/pak#423).

• Better installation output. Standard output and error are now
  collected together (0669f0f8c).

• The solver is now doing a better job when multiple versions of the
  same package are present in the same repository
  (r-lib/actions#559).

• pkg_name_check() now works again, it needed a fix after changes at
  https://crandb.r-pkg.org.

• Explicit package names in local and URL package sources, as in
  package=local::... orpackage=url::... are now parsed correctly in
  dependencies.

• pkgdepends is now more robust toArchs fields missing from the CRAN
  metadata for packages with compiled code
  (r-lib/pak#448).

• url:: packages now always work correctly, even if the digest package is
  not installed (r-lib/pak#433).

• pkgdepends is now more robust when installing packages from subdirectories
  of GitHub repositories (r-lib/pak#431,
  @paleolimbot).

• Parameters?reinstall,?source and?ignore now work correctly when
  specified in thepackage=?parameter format (#294).

Contributors

• The?ignore parameter works correctly now.

• dependency resolution now does not fail if a package is not found.

• pkgdepends can now installurl:: remotes from GitHub.

• pkgdepends now does not fail when the package of a.tar.gz GitHub
  snapshot is in a subdirectory, or in a subdirectory of a subdirectory.

• pkgdepends now errors early if it cannot deduce the name of the package
  from aRemotes orConfig/Needs/* entry.

• Solver failures now include details in some cases where previously they
  did not.

• pkgdepends can now update packages in Docker containers where the
  old version was installed in the different Docker later
  (r-lib/pak#251)

• pkgdepends errors are now user friendlier and better formatted.

• The dependency solver now uses better heuristics and does not
  (effectively) freeze if multiple repositories have multiple versions of
  the same packages (e.g. RSPM and CRAN) (#277).
