gitlabr 2.1.0

Breaking changes

Functions deprecated since version 0.7 are removed
Transfer ownership of the project to ThinkR-open

use_gitlab_ci() allows to decide whether to update R packages during the CI pipeline
Add vignette to explain how to use ‘gitlabr’ with GitLab CI
gl_new_group(), gl_edit_group(), gl_delete_group(), gl_list_groups(), gl_list_sub_groups() to deal with groups on a GitLab instance (@mpolano)
gl_new_subgroup() to create a subgroup in a group (@margotbrd)

gl_list_project_members() and gl_list_group_members to retrieve members of a project or a group (#61, @datawookie)
gitlab() queries allow for a vector of parameters to be passed to the API. This is needed when the API asks for an array (@klmr)

multilist_to_tibble() transforms a deep structured nested list from an API into a tibble (#86, @statnmap, @ymansiaux)

gl_file_exists(), gl_list_files(), gl_push_file(), gl_delete_file() now work with files in subdirectories
Fix handling file path in sub-directories in gl_push_file() (#73, #111)
Fix combination of page and max_page for infinite pagination (#90)
Fix auto_format=FALSE (#82)

Connection now uses the token as “header” instead of being sent clearly in the URL (#66, @ei-ds)
gl_list_group_projects() lists projects of a group (@Yoshinobu-Ishizaki)

Default branch is named main whenever required.
- This can be changed with gitlabr_options_set("gitlabr.main", "master")
All project-specific functions get project as first parameter. Changes apply to:
- gl_get_comments(),gl_to_issue_id(), gl_get_issue_comments(), gl_get_commit_comments(), gl_edit_comment(), gl_edit_issue_comment(), gl_edit_commit_comment()
- gl_repository()
- gl_get_issue(), gl_to_issue_id(), gl_new_issue(), gl_create_issue(), gl_edit_issue(), gl_close_issue(), gl_reopen_issue(), gl_assign_issue(), gl_unassign_issue()
Changed use of api_version = "v4" by api_version = 4
Changed use of force_api_v3 = TRUE by api_version = 4 for deprecation by default

New use of use_gitlab_ci() with pre-defined templates
Add new functions to manage projects: gl_get_project(), gl_new_project(), gl_edit_project(), gl_delete_project()
Update documentation: recommend using gl_* functions

gl_archive() is used to archive a project (not to download an archive)
fix use of max_page with gl_() functions calling gitlab()
Correction of api that downloaded twice the first page when page == "all"
Reduce max_page in examples and tests to retrieve content to allow to work with big GitLab servers like Gitlab.com
Change maintainer
Update CONTRIBUTING for tests with Gitlab.com
update_gitlabr_code() removed

gl_create_issue is introduced as new alias for gl_new_issue
tests are migrated and adapted to test server https://test-gitlab.points-of-interest.cc and to gitlab version 11.6. More specifically a private access tokens is used and login via username and password is no longer possible.

Support for GitLab API v4 (default from GitLab version 9.0 onward) was added. GitLab API v4 is now the default used by gitlabr, but using the old API (v3) is still possible, see details section “API version” of the documentation of gl_connection.
- Several convenience functions now have a force_api_v3 parameter to force old API version logic.
- Issues are now identified by project-wide id and not global iid, according to API v4 logic.
- Function gl_builds was replaced by gl_pipelines and gl_jobs to reflect API v4 logic.
push_to_remotes parameter was added to use_gitlab_ci such that gitlab CI can be used conveniently for pushing to remote repositories.
Examples were added to almost all function reference pages.
In case of Server Error (HTTP Status 5xx), gitlabr now performs up to 3 retries, waiting 25 seconds in between. This is mostly to catch errors due to slow server responses, when the packages test suite is run.

There is no gitlabr 0.8. Version number 0.9 was used to align with GitLab version 9.0, for which this version is appropriate.
