                 Changes in version 2.4.2 (2021-11-30)                  

  - Gábor Csárdi is now the maintainer.
  - bioc_version() now points to the most recent (2021-10-27)
    Bioconductor release, v3.14 (@stufield, #664).
  - Fix regex to handle user names in URL in git_remote, add regression
    tests (@achimgaedke, #646).

                 Changes in version 2.4.1 (2021-09-29)                  

  - pkgbuild is no longer accidentally loaded even in standalone mode
    (#548)
  - The internal GitHub token used to increase rate limits has been
    regenerated.
  - Using remote_package_name.git2r_remote now passes credentials when
    looking up the package DESCRIPTION (#633, @rnorberg)
  - Using remote_package_name.git2r_remote and
    remote_package_name.xgit_remote, http responses returning an invalid
    DESCRIPTION or that redirect to another page will now fallback to
    return NA instead of throwing an error when trying to parse the
    unexpected content (#628, @dgkf).
  - Fix regex that breaks git protocol in git_remote (@niheaven #630).
  - Clarify github_pull() documentation (@ms609 #640).

                 Changes in version 2.4.0 (2021-06-02)                  

  - Re-license as MIT. (#551)

  - Fix bug in install_bioc() when using version='devel'. The code will
    now pull from the git HEAD, not a branch named 'HEAD' (@bbimber,
    #612).

  - skip tests for download.file(method = "internal"), on R > 4.1, since
    that method is now defunct on those versions.

  - system_requirements() now works as intended if only the os argument
    is used (@mdneuzerling, #609)

  - remote_package_name.git2r_remote and remote_package_name.xgit_remote
    now get correct package name from HTTP(S) git repo's DESCRIPTION
    file, and thus package's DESCRIPTION file's Remotes field could have
    git::http(s)://<host>/<username>/<repo>[.git][@ref] items that
    install remote packages using git via HTTP(S) protocal (@niheaven,
    #603).

                 Changes in version 2.3.0 (2021-04-01)                  

Major changes

  - install_*() functions will no longer fail by default if there
    warnings from install.packages(). Concretely the default value of
    R_REMOTES_NO_ERRORS_FROM_WARNINGS has changed to true from the
    previous value of false. (#403)

Minor improvements and fixes

  - install_bioc() now respects the environment variable R_BIOC_VERSION,
    and will use the git branch corresponding to this Bioconductor
    version (@bbimber, #580).

  - remotes without package names are now unconditionally installed
    (#532, @jakubkovac)

  - It is now possible to specify a custom host for dependencies listed
    in the DESCRIPTION file with Remotes:
    <type>[@host]::<username>/<repo>[@ref]. The ref now supports / in it
    for GitLab repositories as it did for GitHubrepositories. (@dagola,
    #448)

  - Internal package2remote() function now supports local remotes
    created by pak.

  - github_pat() will now check if GITHUB_TOKEN is set if it cannot find
    GITHUB_PAT. (@coatless)

  - system_requirements() now supports querying released packages as
    well as development dependencies (#545)

  - system_requirements() now supports OS name + version in the os
    argument (#549, @krlmlr).

                 Changes in version 2.2.0 (2020-07-21)                  

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).

Minor improvements and fixes

  - 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).

                 Changes in version 2.1.1 (2020-02-15)                  

Minor improvements and fixes

  - Installing mixed binary and source dependencies when the latest
    versions of some packages do not have binaries yet should now
    install dependencies in the correct order to prevent load failures
    (#296)

  - github_error() now also works when a GitHub (Enterprise) server does
    not return information about the rate limit (@dpprdan, #396, #413).

  - install_gitlab passes the quiet argument on to gitlab_pat
    (@michaelchirico, #437)

  - remotes is now resilient against installed packages that declare
    RemoteType: standard but do not include a RemoteRepos or
    RemotePkgType field. In such a case, the values for
    getOption("repos") and getOption("pkgType") will be used
    (respectively).

  - install_gitlab() now installs from repositories in subgroups and
    with dots in their name. subdir is now an explicit argument instead
    of implicit in repo (@robertdj, #259, #420).

  - install() now passes the ellipsis ... to install_deps()
    (@Neil-Schneider, #411)

  - The tests have been updated to work with newer versions of callr and
    R 4.0

                 Changes in version 2.1.0 (2019-06-24)                  

New features

  - install_*() functions gain build_manual and build_vignette arguments
    that previously existed in devtools versions < 2.0 (#353).

  - The interactive menu has been modified to provide more clear
    instructions on the skipping behavior (#207)

  - Credentials are now passed via HTTP headers, to reduce exposure when
    requests fail (#391).

Minor improvements and fixes

  - download() with the external curl download method now always uses -L
    to follow redirects. (#350)

  - update_packages() now has a more informative error message when the
    update fails (#223, #232)

  - install_git() now can take credentials from the global option
    remotes.git_credentials (#378).

  - install_git() now works with SHA references and external git (#389).

  - GitHub remotes that point to branches no longer fail when the branch
    is later deleted (#274).

  - Local remotes whose original location has been moved will no longer
    error when updating (#370).

  - update_deps() no longer sorts the dependencies alphabetically (#296,
    #301)

  - github_resolve_ref() now takes a host parameter (#284)

  - Remotes specific environment variables now accept 0 and 1 as valid
    values (#238)

  - remotes now uses locking by default when installing binary packages,
    which avoids issues when installing binaries that are already open
    in other R processes (#368)

  - update_deps() no longer fails if a local package no longer exists
    (#289)

  - install_version() now errors with a more informative message when
    type is not 'source' (#323)

  - Bioc remote_sha() now always returns a character result (#379)

  - Fix API call for private repositories in install_gitlab (@aornugent,
    #359, #363)

  - git submodules now work if the submodule file is empty
    (@muschellij2, #234)

  - git submodules now work if the R package is stored in a subfolder
    (@pommedeterresautee, #233)

  - install_gitlab() no longer adds the access token twice to the
    request (@aornugent, #363).

  - Bitbucket dependencies now actually use the BITBUCKET_USER and
    BITBUCKET_PASSWORD environment variables (@antoine-sachet, #347).

  - parse_deps() now ignores trailing whitespaces around comparison
    operators in DESCRIPTION fields (@LiNk-NY, #366)

                 Changes in version 2.0.4 (2019-04-10)                  

  - update.package_dependencies() now uses the pkg_type for the cran
    remote rather than a global type attribute, fixing errors when this
    global attribute is lost (#291, #304).

  - Credentials are no longer passed to dependencies, as this breaks
    dependencies which use different credentials or hosts. If you have
    relied on this behavior a more robust way to provide the credentials
    is using the appropriate environment variables, e.g. GITHUB_PAT,
    BITBUCKET_USER etc. (@antoine-sachet, #345).

  - The hash of bitbucket hosts is now correctly retrieved
    (@antoine-sachet, #344)

  - Fix parsing of Additional_Repositories which have a leading newline
    (@tmelliott, #251).

                 Changes in version 2.0.3 (2019-04-09)                  

  - The order of choices for upgrade = "ask" now puts the stable ones
    'All', 'CRAN only', 'none' first, so they always have the same
    numbers (#287).

  - update_submodules() now works with empty .gitmodules files
    (@jsilve24, #329).

  - remotes now understands the "standard" remote type, as produced by
    packages installed from CRAN using pak (#309)

  - install_dev() now supports ref/pull format, e.g.
    install_dev('shiny@v1.2-rc') (@mkearney, #279).

  - Fix return type of install_remote() when there is a circular
    dependency (#225)

  - remote_package_name.github_remote() now works properly on Windows
    (#248)

  - install_bioc() repositories now updated for the Bioconductor 3.8
    release. (#239)

  - install_* functions now set the R_LIBS* environment variables for
    child processes correctly on Windows (@HenrikBengtsson, #253)

  - install_* functions now support the R_REMOTES_UPGRADE environment
    variable, to set the default for the upgrade argument. See README
    for details (@kevinushey, #240).

  - install_* functions perform basic HTTP authentication using HTTP
    headers now. This fixes an issue with install_bitbucket() and
    private repos (#255).

  - install_* functions now respect the download.file.method option, if
    download_file() is used for HTTP.

  - install_* functions now use the libcurl method, if the
    download.file.method option is not set to a different one, and
    libcurl is available. Before, the wininet method was preferred on
    Windows. If you rely on the proxy configuration of wininet, then you
    might want to set the download.file.method option, or use another
    way to set up proxies, see ?download.file.

  - Remotes without package names are now unconditionally installed
    (#246).

  - install_github() now includes a more informative error message when
    the status code is 404, asking the user to check that they have
    spelled the repo owner and repo correctly (included in the error
    message), and that they have the required permissions to access the
    repository.

  - install_* functions (via the underlying private install function)
    now set RGL_USE_NULL="TRUE" in order to avoid errors when running
    headless and installing any package using rgl (@jefferis, ##333)

                 Changes in version 2.0.2 (2018-10-30)                  

  - install_deps() now installs un-installed remotes packages even when
    upgrade = "never" (@ankane, #227)

  - install_version() now removes metadata added as a byproduct of using
    install_url() internally() (#224)

  - install() now avoids converting warnings to errors if
    R_REMOTES_NO_ERRORS_FROM_WARNINGS is unset and
    _R_CHECK_FORCE_SUGGESTS_=false. This avoids failures due to
    Suggested packages potentially being missing.

  - install_bitbucket() now works properly with packages in
    subdirectories (#220)

  - install_deps() now installs un-installed packages even when upgrade
    = "never" (#218)

                 Changes in version 2.0.1 (2018-10-19)                  

  - install_github() now bundles a GitHub PAT which is used on Travis to
    avoid hitting the rate limit too frequently. It also contains a more
    informative error message when the rate limit is hit on how to setup
    a GitHub personal access token.

  - The dialog when upgrade = "ask" now has a 'CRAN only' option, to
    update only CRAN packages.

  - No longer include project specific .Rprofile code in the temporary
    .Rprofile when R_REMOTES_NO_ERRORS_FROM_WARNINGS=false (the
    default).

  - update.package_deps() no longer prompts to install uninstalled
    dependencies, they are always installed (#203).

  - available_packages(), available_packages_set() and
    available_packges_reset() added to allow caching of the
    available.packages() database.

                 Changes in version 2.0.0 (2018-10-11)                  

Breaking changes

  - install_github()'s previously deprecated username argument has been
    removed. (#142)

  - install_deps()'s threads argument has been removed, use the Ncpus
    argument instead (#153, #154)

  - install_git()'s branch argument has been renamed to ref and branch
    has been deprecated.

New features

  - remotes now builds packages by default before installing them. This
    step uses the pkgbuild package, if available. If not, it calls R CMD
    build directly.

  - New install_dev() to install the development version of a CRAN
    package, based on the URL and BugReports fields in the DESCRIPTION
    file (#144).

  - install_()* functions now temporally put Rtools on the PATH when
    necessary, as long as the pkgbuild package is installed.

  - remotes can be forced to use only its internal code by setting the
    environment variable R_REMOTES_STANDALONE = "true". This is useful
    when installing optional dependencies of remotes on Windows, such as
    curl or git2r (#147)

  - When installing, remotes now errors on warnings, to catch cases
    where packages are only partially installed. This often happens on
    windows when the package dll is opened in another R process (#113).

  - install_() functions now pass arguments, including authentication
    information and upgrade down to dependencies (#53, #86, #87).

  - install_() functions allow the selection of a subset of packages to
    upgrade, in interactive mode, when upgrade = "ask".

  - install_git() now supports passing credentials, when it is used with
    git = "git2r" (#106)

  - install_() functions now return the name of the package(s) which
    were installed (#55).

  - git submodules are now installed if they exist and a git client is
    available (#138, #133, #103, #82).

  - New install_gitlab() and install_bioc() functions, to install gitlab
    and bioc remote types.

  - remotes now uses the same SHA updating logic for remotes as
    devtools, including checking if the SHA of the remote has changed
    since the last installation. (#135)

  - install_url() can now install package binaries on windows
    (r-lib/devtools#1765)

Minor improvements and fixes

  - install_deps() et al. now do not rewrite the type argument from both
    to binary to allow falling back to source. This fixes various
    installation failures.

  - remotes now looks up GitHub package names locally, if possible, and
    uses the GitHub REST API (if the curl package is available, and not
    in standalone mode). This makes the remote lookup about 10x faster
    when the remote package has not changed since the last install.

  - Using a GITHUB_PAT no longer prints diagnostic messages by default
    (r-lib/devtools#1752).

  - remotes now always uses https URLs for R versions that support them
    (@ankane, #139)

  - Do not include the BioCextra repository in versions after it was
    deprecated (R 3.5+, Bioc 3.6+).

  - install_() functions now download tarballs (.tar.gz) files rather
    than zip archives (.zip). This results in generally smaller files
    and avoids issues with script permissions being lost and strange
    behavior of some external unzip programs on Windows (#96).

  - Dependency parsing is now more robust to whitespace around the
    dependency specifications (#73).

  - standardise_dep() exported, for use in devtools.

  - install_local() now defaults to the current directory.

  - install_bitbucket() now correctly supports authentication, and the
    subdir argument.

  - install_() functions give a helpful warning when the package has
    long path names, on Windows. In this case building the package
    usually fails. (#84, #178).

  - install_() functions have now a more robust way of handling various
    tar programs on Windows (#172).

  - install_() functions now give a helpful warning on older R versions,
    on Windows, if R.home() contains a space character. Installation
    usually fails in this case.

  - GitHub API errors now give better error messages, including data
    about the API rate limits.

                 Changes in version 1.1.1 (2017-12-20)                  

  - Accept HTTPS, SSH, or various browser URLs in GitHub repo
    specification, @jennybc, #90, #109, #112

                 Changes in version 1.1.0 (2017-07-09)                  

  - URL encode GitHub references, to allow installing from
    non-alphanumeric branch or tags, @krlmlr #38

  - Better cooperation with proxy servers, and better download method
    selection on Windows, @cderv, #45, #46

  - install_deps() supports tar balls, #47

  - Allow training slash in GitHub repo specification, #54

  - Work around on some Linux systems, where unzip is set to the empty
    string, @HenrikBengtsson, #57

  - Check for circular dependencies while installing, #31

  - Updated Bioconductor repo URLs for newer BioC versions

                 Changes in version 1.0.0 (2016-09-10)                  

First public release.
