* `git_index_add` will now use the case as provided by the caller on
case insensitive systems. Previous versions would keep the case as
it existed in the index. This does not affect the higher-level
`git_index_add_bypath` or `git_index_add_frombuffer` functions.
* `git_index_add` and `git_index_conflict_add()` will now use the case
as provided by the caller on case insensitive systems. Previous

* The `notify_payload` field of `git_diff_options` was renamed to `payload`
to reflect that it's also the payload for the new progress callback.
