2.0.0
  - Windows: update to libgit2-1.7.1 + libssh-1.11.0 + openssl-3.1.2

1.9.3
  - Add git_commit_stats() function
  - Add git_ignore_path_is_ignored() function
  - Fix protect bug in git_submodule_list()

1.9.2
  - Replace sprintf with snprintf for CRAN

1.9.1
  - Fix the Wstrict-prototype warnings
  - Use special static libgit2 bundle for openssl-3 distros.

1.9.0
  - Add support for the new ED25519 keys when authenticating over SSH

1.8.0
  - The static libgit2 for win/mac/linux are all 1.4.2 with a patched version
    of libssh 1.10.1. This should fix problems with the latest release versions
    of libgit2 and libssh2.
  - The patched libssh2 builds should now support RSA-SHA2, which re-enables
    authentication with GitHub using an RSA key.
  - On production Linux systems (x64 RHEL/Ubuntu) default to building using the
    static libgit2 because of above reasons. Set USE_SYSTEM_LIBGIT2=1 to force
    building against a local libgit2 on these platforms.

1.7.1
  - The static libgit2 for linux has been updated to 1.5.0 (this is only used
    on linux systems where no sufficient libgit2 is available).

1.7.0
  - git_status() gains parameter pathspec
  - git_ls() gains paremeter 'ref' and works with bare repositories

1.6.0
  - We recommend at least libgit2 1.0 now
  - Windows: update to libgit2 1.4.2
  - Tests: switch to ECDSA keys for ssh remote unit tests
  - git_log() gains a parameter 'after'

1.5.0
  - Windows: use ${HOMEDRIVE}${HOMEPATH} path as home if it exists, to match
    git-for-windows. On most systems this is the same as ${USERPROFILE}.
  - git_commit_info() no longer includes $diff by default because it can be huge.
    Please use git_diff() instead if you need it.

1.4.3
  - Fix a unit test for some older versions of libgit2

1.4.2
  - Make unit tests more robust against network fail and renamed branches
  - Windows / MacOS: update to libgit2 1.3.0

1.4.1
  - Fix compile error with some older version of libgit2
  - MacOS: automatically use static libs when building in CI

1.4.0
  - Windows / MacOS: update to libgit2 1.2.0
  - New function git_branch_move()
  - git_branch_checkout gains 'orphan' parameter

1.3.2
  - Fix unit test because GitHub has disabled user/pass auth

1.3.1
  - Windows: fix build for ucrt toolchains
  - Solaris: disable https cert verfication

1.3.0
  - Some encoding fixes for latin1 paths, especially non-ascii Windows usernames.

1.2.0
  - New git_stat_files() function.

1.1.0
  - On x86_64 Linux systems where libgit2 is too old or unavailable, we automatically
    try to download a precompiled static version of libgit2. This includes CentOS 7/8
    as well as Ubuntu 16.04 and 18.04. Therefore the PPA should no longer be needed.
    You can opt-out of this by setting an envvar: USE_SYSTEM_LIBGIT2=1
  - Add tooling to manually find and set the location of the system SSL certificates
    on such static builds, and also for Solaris.
  - Add several functions to work with submodules.
  - Globally enable submodule-caching for faster diffing.
  - Refactor internal code to please rchk analysis tool.

1.0.2
  - git_branch_list() gains a parameter 'local'
  - Windows / MacOS: update to libgit2 1.1.0
  - Do not use bash in configure

1.0.1
  - git_branch_list() and git_commit_info() gain a date field
  - Bug fixes

1.0
  - Lots of new functions
  - Windows and MacOS now ship with libgit2-1.0.0
  - Do not advertise HTTPS support in startup message because it should
    always be supported.
  - Config setters return previous value invisibly (#37)
  - Conflicted files are reported by git_status() (#40)
  - Windows: libgit2 now finds ~/.gitconfig under $USERPROFILE (instead of Documents)
  - A git_signature object is now stored as a string instead of an externalptr
  - The 'name' parameter in git_remote_ functions has been renamed to 'remote'

0.3

  - git_push() sets upstream if unset
  - workaround for ASAN problem in libssh2
  - lots of tweaks and bug fixes

0.1
