Release remotes 2.2.0 · r-lib/remotes

New functions and features

New system_requirements() function to query the Public RStudio Package Manager for system requirements for a package (and its dependencies)
Remotes functions can now install dependencies from additional DESCRIPTION fields, e.g. passing dependencies = "Config/Needs/website" will install the dependencies listed in the Config/Needs/website: field in the package's DESCRIPTION.
Prefixing fields with Config/Needs allows them to pass R CMD check without a NOTE, so it is the recommended format for these extra dependencies.
install_*() family of functions now use the default branch in the repository, not the master branch (@MyKo101,#508).

Internal functions remote_download(), remote_metadata(), remote_package_name() and remote_sha() are now exported, so 3rd party packages could provide methods for new remote types (#509, #56)
Internal functions add_metadata(), github_remote() are now exported. They are mainly for 3rd party extensions and should not be used by most users (#485).
install_version() now keeps searching subsequent repositories for the requested version, rather than failing if the version it finds in an early repository is unsuitable. (#305, @kenahoo)
install_version() now understands specifications like '>= 1.0' or '>= 1.12.0, < 1.14' to install the first version of the package it can find that satisfies the criteria. (#305, @kenahoo)
install_version() now avoids use of base::url(), as prior to R 3.6.2 it had a bug when downloading large files (#463)
parse_submodules() internal regular expression is now PCRE 2 compatible (#502, @jan-glx)
update_packages() argument force has been deprecated and no longer has any effect (#521)
Another fix for the mixed binary and source dependency issue, it should hopefully be fully squashed now (#296)
The upgrade menu is now interruptible in RStudio (#489).
Internal GitHub functions now correctly handle cases when characters are not representable in the default locale, but are representable in UTF-8 (#492).
