usethis 1.6.0

GitHub actions

• New use_github_actions(), use_github_action_check_release(),
  use_github_action_check_full(), use_github_action_pr_commands(),
  to set up a GitHub Actions for a package (@jimhester).

• We now recommend GitHub Actions instead of Travis-CI or AppVeyor, and strongly
  recommend upgrading your packages.

• Fix use_github_action() URL parameter to ensure custom URLs are allowed.
  (@coatless, #1065).

Package creation

• create_package() gains a roxygen argument. If TRUE (the default),
  it adds a RoxygenNote field to the DESCRIPTION (which means the first run
  of devtools::check() will re-document the package, #963), and creates an
  empty NAMESPACE (which means you'll always need an explicit @export
  if you want to export functions, #927). It also turns markdown processing
  on by default (#911).

• use_rstudio() now sets the LineEndingConversion to Posix so that
  packages created using usethis always use LF line endings, regardless of
  who contributes to them (#1002).

• In the usethis.description option, you can now set Authors@R = person()
  directly, without having to wrap in additional layer of quotes. If setting
  this in your .Rprofile, you'll need to use utils::person() since the utils
  package isn't loaded until after your profile is executed.

PR helpers

• A new article Pull request helpers
  demonstrates how to use the pr_*() functions (@mine-cetinkaya-rundel, #802).

• pr_finish() checks that you don't have any local changes (#805), and can
  optionally finish any PR, not just the current (#1040).

• pr_pause() and pr_fetch() now automatically pull to get latest changes
  (#959, #960) and refresh RStudio's git pane (#706).

• pr_push() now works for a repository with no open pull requests
  (@maurolepore, #990).

• pr_pull() gives more information about which files have merge conflicts
  and automatically opens conflicted files for editing (#1056).

Other new features

• New rename_files() makes it easy to rename paired R/ and test/ files
  (#784).

• New ui_silence() makes it easier to selectively silence some UI output.

• New use_agpl3_license() (@pachamaltese, #870).

• New use_data_table() to set up a package for Import-ing data.table
  (@MichaelChirico, #897).

• use_latest_dependencies() replaces use_tidy_version() as the new name
  better reflect its usage (#771).

• New use_lifecycle() helper to import the lifecycle badges for functions and
  arguments in your package. Learn more at https://lifecycle.r-lib.org/.

• use_release_issuue() will include additional bullets if your package
  includes release_bullets() function which returns a character
  vector (and the package has been loaded with load_all()) (#941).

Minor improvements and bug fixes

• When writing files, usethis now respects line endings. Default line endings
  are taken from the .Rproj file (if available), otherwise the DESCRIPTION,
  otherwise the first file found in R/, then all else failing to your
  platform default (#767). It should do a better job of preserving UTF-8 files
  on windows (#969).

• browse_github() now always goes to the canonical GitHub site:
  https://github.com/user/repo. This is slightly worse than the current
  behaviour but makes the function more consistent across packages, and
  considerably simplifies the implementation.

• browse_circle() opens the project dashboard on Circle CI.

• create_download_url() is a new helper for making "ZIP file download"
  URLs suitable for use with use_course() and use_zip(), starting with the
  URLs that mere mortals can usually get their hands on in a browser
  (@fmichonneau, #406).

• create_package() no longer fails partway through if you have a malformed
  usethis.description option (#961).

• create_package() will now create a package in a symlink to a directory
  (#794).

• create_package() and use_description() gain a check_name argument to
  control whether to check for package names invalid for CRAN (@noamross, #883).

• edit_file() and use_test() gain an open parameter that allows you to
  control whether or not the function is opened for editing by the user (#817).

• edit_rstudio_snippets() makes it more clear which snippet types are
  allowed and that user's snippets mask the built-in snippets (@GegznaV, #885).

• git_sitrep() now reports project-specific user name and email, if set
  (#837), and email(s) associated with your GitHub account (@dragosmg, #724).

• ui_yeah() and ui_nope() allow you to override the default "yes" and
  "no" strings and to opt-out of shuffling (@rundel, #796).

• use_circleci() uses correct delimiters in template (@jdblischak, #835).

• use_circleci_badge() is now exported (@pat-s, #920).

• use_code_of_conduct() now generates an absolute link to code of conduct on
  pkgdown website or original source to avoid R CMD check issues (#772).

• use_course() and use_zip() are now equipped with some retry capability,
  to cope with intermittent failure or the need for a longer connect timeout
  (#988).

• use_data() automatically bumps R dependency to 2.10 (#962).

• use_data_raw() template quotes the dataset name correctly
  (#736, @mitchelloharawild).

• use_description_defaults() now shows the default fields combined with
  any options that you have set.

• use_dev_package() now supports packages installed from any remote type,
  not just GitHub (@antoine-sachet, #1071).

• use_git() will now create initial commit if needed (#852).

• use_github_release() no longer fails if you have no news bullets (#1048).

• use_github_release() now tags the latest local commit instead of the latest
  remote commit on the default branch (@davidchall, #1029).

• use_gpl3_license() now completes the license by providing additional
  information in a file named LICENSE, just like use_mit_license() and
  friends (@Cervangirard, #683).

• use_logo() now generates the correct href if the pkgdown url is set
  (@mitchelloharawild, #986).

• use_make() gains missing closing parenthesis (@ryapric, #804).

• use_markdown_template() no longer uses an unexported function in its
  default arguments (@fmichonneau, #761).

• use_testthat() and use_test() now work in projects, not just packages
  (#1017).

• use_test() works on Windows when called without arguments (#901).

• use_tidy_issue_template() uses current github format (@Maschette, #756).

• use_travis(), use_travis_badge(), and browse_travis(), now default
  to ext = "com" since travis-ci.com is now recommended it over travis-ci.org
  (@riccardoporreca, #1038).

• use_release_issue() reminds you to re-generate README.md,
  if needed (#767).

• use_r() and use_test() throw a clear error if multiple names are provided
  (@strboul, #862).

• use_rcpp() and use_c() now ensure src/ contains at least one .cpp or
  .c placeholder file, so that the package can be built (@coatless, #720).

• usethis.destdir is a new option that is consulted when deciding where to
  put a new folder created by use_course() or create_from_github()
  (@malcolmbarrett, #1015).
