### Breaking API changes
v0.26
-----
### Changes or improvements
* Support for opening, creating and modifying worktrees.
* We can now detect SHA1 collisions resulting from the SHAttered attack. These
checks can be enabled at build time via `-DUSE_SHA1DC`.
* Fix for missing implementation of `git_merge_driver_source` getters.
* Fix for installed pkg-config file being broken when the prefix contains
spaces.
* We now detect when the hashsum of on-disk objects does not match their
expected hashsum.
* We now support open-ended ranges (e.g. "master..", "...master") in our
revision range parsing code.
* We now correctly compute ignores with leading "/" in subdirectories.
* We now optionally call `fsync` on loose objects, packfiles and their indexes,
loose references and packed reference files.
* We can now build against OpenSSL v1.1 and against LibreSSL.
* `GIT_MERGE_OPTIONS_INIT` now includes a setting to perform rename detection.
This aligns this structure with the default by `git_merge` and
`git_merge_trees` when `NULL` was provided for the options.
* Improvements for reading index v4 files.
* Perform additional retries for filesystem operations on Windows when files
are temporarily locked by other processes.
### API additions
* New family of functions to handle worktrees:
* `git_worktree_list()` lets you look up worktrees for a repository.
* `git_worktree_lookup()` lets you get a specific worktree.
* `git_worktree_open_from_repository()` lets you get the associated worktree
of a repository.
a worktree.
* `git_worktree_add` lets you create new worktrees.
* `git_worktree_prune` lets you remove worktrees from disk.
* `git_worktree_lock()` and `git_worktree_unlock()` let you lock
respectively unlock a worktree.
* `git_repository_open_from_worktree()` lets you open a repository via
* `git_repository_head_for_worktree()` lets you get the current `HEAD` for a
linked worktree.
* `git_repository_head_detached_for_worktree()` lets you check whether a
linked worktree is in detached HEAD mode.
* `git_repository_item_path()` lets you retrieve paths for various repository
files.
* `git_repository_commondir()` lets you retrieve the common directory of a
repository.
* `git_branch_is_checked_out()` allows you to check whether a branch is checked
out in a repository or any of its worktrees.
* `git_repository_submodule_cache_all()` and
`git_repository_submodule_cache_clear()` functions allow you to prime or clear
the submodule cache of a repository.
* You can disable strict hash verifications via the
`GIT_OPT_ENABLE_STRICT_HASH_VERIFICATION` option with `git_libgit2_opts()`.
* You can enable us calling `fsync` for various files inside the ".git"
directory by setting the `GIT_OPT_ENABLE_FSYNC_GITDIR` option with
`git_libgit2_opts()`.
* You can now enable "offset deltas" when creating packfiles and negotiating
packfiles with a remote server by setting `GIT_OPT_ENABLE_OFS_DELTA` option
with `GIT_libgit2_opts()`.
* You can now set the default share mode on Windows for opening files using
`GIT_OPT_SET_WINDOWS_SHAREMODE` option with `git_libgit2_opts()`.
You can query the current share mode with `GIT_OPT_GET_WINDOWS_SHAREMODE`.
* `git_transport_smart_proxy_options()' enables you to get the proxy options for
smart transports.
* The `GIT_FILTER_INIT` macro and the `git_filter_init` function are provided
to initialize a `git_filter` structure.
### Breaking API changes
* `clone_checkout_strategy` has been removed from
`git_submodule_update_option`. The checkout strategy used to clone will
be the same strategy specified in `checkout_opts`.

* `git_remote_connect()` now accepts `git_proxy_options` argument, and
`git_fetch_options` and `git_push_options` each have a `proxy_opts` field.

during a merge.

What It Can Do
==============
The goal of this library is to allow its users the ability to handle Git data in
their applications from their programming language of choice, as is used in
production for many applications including the GitHub.com site, in Plastic SCM
and also powering Microsoft's Visual Studio tools for Git.
libgit2 provides you with the ability to manage Git repositories in the
programming language of your choice. It's used in production to power many
applications including GitHub.com, Plastic SCM and Visual Studio Team Services.

As libgit2 is purely a consumer of the Git system, we have to
adjust to changes made upstream. This has two major consequences:
* Some changes may require us to change provided interfaces. While we try to
implement functions in a generic way so that no future changes are required,
we cannot promise a completely stable API.
* As we have to keep up with changes in behavior made upstream, we may lag
behind in some areas. We usually to document these incompatibilities in our

Alternatively you can run the test suite directly using,
