CRAN release v0.19.0

IMPROVEMENTS

• Updated the bundled libgit2 source code to commit (15e1193)
  (v0.26.0) from 14 June 2017.

• Added 'checkout' argument to 'clone()'. Allows to control whether
  checkout of HEAD is performed after the clone is complete. Setting
  'checkout=FALSE' has similar effect as the git command line option
  '--no-checkout'. Andrzej K. Oles in #282.

BUG FIXES

• Fixed memory protection errors in the git2r C source code reported
  by the 'rchk' tool.

• Added missing calls to 'R_forceSymbols' and 'R_useDynamicSymbols' in
  the C init function.

• Enable argument 'all' to commit multiple modified (or deleted)
  files. John Blischak in #283

• Changed the configure script to determine the architecture of the
  machine earlier in order to fix an unsupported architecture error
  encountered on CentOS (#268, #288).

CRAN release v0.18.0

BUG FIXES

• This is a bug-fix release to solve an error introduced in the build
  configuration on mac in version 0.17.0. The package failed with
  'unable to load shared object', see issue #267.

CRAN release v0.17.0

IMPROVEMENTS

• Updated the bundled libgit2 source code to commit (6b0510e) from 20
  December 2016.
• Static linking of LibSSH2 on mac to support redistributable binary
  package with SSH transport enabled. Version 1.8.0 of LibSSH2 is
  downloaded and built from 'https://www.libssh2.org/download/'.

CRAN release v0.16.0

git2r 0.16.0

IMPROVEMENTS

• Updated libgit2 source code to commit (6b0510e) from
  17 November 2016.
• Add the option 'all_untracked' to the 'status' method to show
  individual files in untracked directories if the 'untracked' option
  is TRUE.
• Add the 'tag_delete' method to delete an existing tag reference.
• Update build configuration to support OpenSSL 1.1.0.
• If the the 'getPass' package is installed the 'cred_ssh_key' method
  to create a new passphrase-protected ssh key credential object will
  call the 'getPass::getPass()' method if the private key is
  passphrase protected to allow for interactive input of the
  passphrase. The 'getPass' package is a suggested package. (Peter
  Meissner in PR #254)
• Add 'path' argument to the 'reset' method to enable path-specific
  unstage, i.e. resets the index entries for all paths to their state
  at HEAD

BUG FIXES

• Build configuration: use portable string equality comparison
  operator. This fixes the build e.g. for those without Bash as
  /bin/sh. (Sander Maijers in PR #243).

CRAN release v0.15.0

git2r 0.15.0

IMPROVEMENTS

• Build configuration: 'pkg-config' is now used to find 'libssl', if
  possible (Elias Pipping in PR #231).
• Added a method to coerce a 'git_commit' object to a 'data.frame'.
• Added the method 'is_branch' to check if an object is a
  'git_branch'.

BUG FIXES

• Build configuration: fixed installation with parallel make (Kirill
  Müller in PR #228).

CRAN release v0.14.0

git2r 0.14.0

IMPROVEMENTS

• Updated libgit2 source code to commit (785d8c48) from
  2016-03-04. This is release v0.24.0 of libgit2.
• Refactoring of the build scripts.
• Added a check that the configuration key is valid when setting a
  configuration variable and output a warning if the key is invalid.
• The status method now prints "working directory clean" instead of
  nothing when the working directory is clean.
• Added the 'refspec' argument to the 'fetch' method to specify the
  refs to fetch and which local refs to update.
• Added a workaround to the 'commit' method to list commits in a
  shallow clone since the libgit2 library does not yet support this.

CRAN release v0.13.1

git2r 0.13.1

BUG FIXES

• This is a bug-fix release to solve problems introduced in version
  0.12.1:
  • The bundled libgit2 source code has been reverted to commit
    (98f7bd2) from 2015-08-05 (same as in v0.11.0) to fix memory
    alignment errors (clang-UBSAN and gcc-UBSAN).
  • OpenSSL is now used again on OS X to provide the cryptographic
    support for HTTPS connections to fix a significant compiler
    warning (arithmetic on a pointer to void is a GNU extension
    [-Wpointer-arith]) on r-devel-osx-x86_64-clang.
  • Several fixes to the build configuration on non-Windows platforms.

CRAN release v0.12.1

  git ls-remote command.

  variable with the secret. Default value for the name is GITHUB_PAT.

  'GIT_OPT_SET_SSL_CERT_LOCATIONS'

CHANGES

• Improvments to the cred_* functions documentation.
• Add the following default arguments to the 'cred_ssh_key' method:
  publickey = '/.ssh/id_rsa.pub' and privatekey = '/.ssh/id_rsa'
• On OSX, cascade CPPFLAGS and LDFLAGS to libssh2 build to allow
  libssh2 to be built against a user-installed openssl, discovered by
  configure or from R's Makeconf. Necessary to build on OS X ≥ 10.11
• On OS X, SecureTransport is now used to provide the cryptographic
  support for HTTPS connections insead of OpenSSL.
• The search for libssh2 during configuration (non Windows) is now
  done via pkg-config.

  repository is searched for with 'discover_repository' in the current
  working directory.
• Add name of branch to each item in branch_list.
• Add name of tag to each item in tags list.
• Add S4 class 'cred_env' to pass credentials in environment
  variables.
• SSH transport on Windows. This requires 'LibSSH2' and
  'OpenSSL'. These two libraries are downloaded from
  'https://github.com/rwinlib' during configuration of the package.
• Static linking of LibSSH2 on OSX to support redistributable binary
  package with SSH transport enabled. Version 1.6.0 of LibSSH2 is
  downloaded and built from 'https://github.com/libssh2/libssh2'.

IMPROVEMENTS

  'git_repository'.
• Updated libgit2 source code to commit (98f7bd2) from 2015-08-05.

  found on non-Windows systems.
• Changed configuration to raise error if the iconv library is not
  found on OSX.
