allow for specifying the expression from the user to be put into the
reflog.
+* `git_rebase_commit` now returns `GIT_EUNMERGED` when you attempt to
+ commit with unstaged changes.
+
+* On Mac OS X, we now use SecureTransport to provide the cryptographic
+support for HTTPS connections insead of OpenSSL.
+
+* Checkout can now accept an index for the baseline computations via the
+ `baseline_index` member.
+
+* The configuration for fetching is no longer stored inside the
+ `git_remote` struct but has been moved to a `git_fetch_options`. The
+ remote functions now take these options or the callbacks instead of
+ setting them beforehand.
+
+* The index now uses diffs for `add_all()` and `update_all()` which
+ gives it a speed boost and closer semantics to git.
+
+* The ssh transport now reports the stderr output from the server as
+ the error message, which allows you to get the "repository not
+ found" messages.
+
+* `git_index_conflict_add()` will remove staged entries that exist for
+ conflicted paths.
+
+* The flags for a `git_diff_file` will now have the `GIT_DIFF_FLAG_EXISTS`
+ bit set when a file exists on that side of the diff. This is useful
+ for understanding whether a side of the diff exists in the presence of
+ a conflict.
+
+* The constructor for a write-stream into the odb now takes
+ `git_off_t` instead of `size_t` for the size of the blob, which
+ allows putting large files into the odb on 32-bit systems.
+
+* The remote's push and pull URLs now honor the url.$URL.insteadOf
+ configuration. This allows modifying URL prefixes to a custom
+ value via gitconfig.
+
+* `git_diff_foreach`, `git_diff_blobs`, `git_diff_blob_to_buffer`,
+ and `git_diff_buffers` now accept a new binary callback of type
+ `git_diff_binary_cb` that includes the binary diff information.
+
+* The race condition mitigations described in `racy-git.txt` have been
+ implemented.
+
+* If libcurl is installed, we will use it to connect to HTTP(S)
+ servers.
+
### API additions
* The `git_merge_options` gained a `file_flags` member.
put into the reflog as the source/target.
* `git_index_add_frombuffer()` can now create a blob from memory
- buffer and add it to the index which is attached to a repository.
+ buffer and add it to the index which is attached to a repository.
+
+* The structure `git_fetch_options` has been added to determine the
+ runtime configuration for fetching, such as callbacks, pruning and
+ autotag behaviour. It has the runtime initializer
+ `git_fetch_init_options()`.
+
+* The enum `git_fetch_prune_t` has been added, letting you specify the
+ pruning behaviour for a fetch.
+
+* A push operation will notify the caller of what updates it indends
+ to perform on the remote, which provides similar information to
+ git's pre-push hook.
+
+* `git_stash_apply()` can now apply a stashed state from the stash list,
+ placing the data into the working directory and index.
+
+* `git_stash_pop()` will apply a stashed state (like `git_stash_apply()`)
+ but will remove the stashed state after a successful application.
+
+* A new error code `GIT_EEOF` indicates an early EOF from the
+ server. This typically indicates an error with the URL or
+ configuration of the server, and tools can use this to show messages
+ about failing to communicate with the server.
+
+* `git_diff_index_to_workdir()` and `git_diff_tree_to_index()` will now
+ produce deltas of type `GIT_DELTA_CONFLICTED` to indicate that the index
+ side of the delta is a conflict.
+
+* The `git_status` family of functions will now produce status of type
+ `GIT_STATUS_CONFLICTED` to indicate that a conflict exists for that file
+ in the index.
+
+* `git_index_entry_is_conflict()` is a utility function to determine if
+ a given index entry has a non-zero stage entry, indicating that it is
+ one side of a conflict.
+
+* It is now possible to pass a keypair via a buffer instead of a
+ path. For this, `GIT_CREDTYPE_SSH_MEMORY` and
+ `git_cred_ssh_key_memory_new()` have been added.
+
+* `git_filter_list_contains` will indicate whether a particular
+ filter will be run in the given filter list.
+
+* `git_commit_header_field()` has been added, which allows retrieving
+ the contents of an arbitrary header field.
### API removals
+* `git_remote_save()` and `git_remote_clear_refspecs()` have been
+ removed. Remote's configuration is changed via the configuration
+ directly or through a convenience function which performs changes to
+ the configuration directly.
+
+* `git_remote_set_callbacks()`, `git_remote_get_callbacks()` and
+ `git_remote_set_transport()` have been removed and the remote no
+ longer stores this configuration.
+
+* `git_remote_set_fetch_refpecs()` and
+ `git_remote_set_push_refspecs()` have been removed. There is no
+ longer a way to set the base refspecs at run-time.
+
### Breaking API changes
+* `git_smart_subtransport_cb` now has a `param` parameter.
+
* The `git_merge_options` structure member `flags` has been renamed
to `tree_flags`.
* `git_note_default_ref()` now uses a `git_buf` to return the string,
as the string is otherwise not guaranteed to stay allocated.
+* `git_rebase_operation_current()` will return `GIT_REBASE_NO_OPERATION`
+ if it is called immediately after creating a rebase session but before
+ you have applied the first patch.
+
+* `git_rebase_options` now contains a `git_checkout_options` struct
+ that will be used for functions that modify the working directory,
+ namely `git_checkout_init`, `git_checkout_next` and
+ `git_checkout_abort`. As a result, `git_rebase_open` now also takes
+ a `git_rebase_options` and only the `git_rebase_init` and
+ `git_rebase_open` functions take a `git_rebase_options`, where they
+ will persist the options to subsequent `git_rebase` calls.
+
+* The `git_clone_options` struct now has fetch options in a
+ `fetch_opts` field instead of remote callbacks in
+ `remote_callbacks`.
+
+* The remote callbacks has gained a new member `push_negotiation`
+ which gets called before sending the update commands to the server.
+
+* The following functions now longer act on a remote instance but
+ change the repository's configuration. Their signatures have changed
+ accordingly:
+
+ * `git_remote_set_url()`, `git_remote_seturl()`
+ * `git_remote_add_fetch()`, `git_remote_add_push()` and
+ * `git_remote_set_autotag()`
+
+* `git_remote_connect()` and `git_remote_prune()` now take a pointer
+ to the callbacks.
+
+* `git_remote_fetch()` and `git_remote_download()` now take a pointer
+ to fetch options which determine the runtime configuration.
+
+* The `git_remote_autotag_option_t` values have been changed. It has
+ gained a `_FALLBACK` default value to specify no override for the
+ configured setting.
+
+* `git_remote_update_tips()` now takes a pointer to the callbacks as
+ well as a boolean whether to write `FETCH_HEAD` and the autotag
+ setting.
+
+* `git_remote_create_anonymous()` no longer takes a fetch refspec as
+ url-only remotes cannot have configured refspecs.
+
+* The `git_submodule_update_options` struct now has fetch options in
+ the `fetch_opts` field instead of callbacks in the
+ `remote_callbacks` field.
+
+* The `push` function in the `git_transport` interface now takes a
+ pointer to the remote callbacks.
+
+* The `git_index_entry` struct's fields' types have been changed to
+ more accurately reflect what is in fact stored in the
+ index. Specifically, time and file size are 32 bits intead of 64, as
+ these values are truncated.
+
+* `GIT_EMERGECONFLICT` is now `GIT_ECONFLICT`, which more accurately
+ describes the nature of the error.
