Changes or improvements
Custom filters can now be registered with wildcard attributes, for
filter=*. Consumers should examine the attributes parameter
checkfunction for details.
Symlinks are now followed when locking a file, which can be
necessary when multiple worktrees share a base repository.
You can now set your own user-agent to be sent for HTTP requests by
You can set custom HTTP header fields to be sent along with requests
by passing them in the fetch and push options.
Tree objects are now assumed to be sorted. If a tree is not
correctly formed, it will give bad results. This is the git approach
and cuts a significant amount of time when reading the trees.
Filter registration is now protected against concurrent
Filenames which are not valid on Windows in an index no longer cause
to fail to parse it on that OS.
Rebases can now be performed purely in-memory, without touching the
git_config_lock()has been added, which allow for
transactional/atomic complex updates to the configuration, removing
the opportunity for concurrent operations and not committing any
changes until the unlock.
git_diff_optionsadded a new callback
progress_cbto report on the
progress of the diff as files are being compared. The documentation of
the existing callback
notify_cbwas updated to reflect that it only
gets called when new deltas are added to the diff.
git_push_optionshave gained a
field to set the extra HTTP header fields to send.
git_stream_register_tls()lets you register a callback to be used
as the constructor for a TLS stream instead of the libgit2 built-in
git_commit_header_field()allows you to look up a specific header
field in a commit.
git_commit_extract_signature()extracts the signature from a
commit and gives you both the signature and the signed data so you
can verify it.
There were no API removals in this release.

versions would keep the case as it existed in the index. This does

git_diff_optionswas renamed to

git_config_level_tenum has gained a higher-priority value
GIT_CONFIG_LEVEL_PROGRAMDATAwhich represent a rough Windows equivalent
to the system level configuration.
git_rebase_init()not also takes a merge options.
The index no longer performs locking itself. This is not something
users of the library should have been relying on as it's not part of
the concurrency guarantees.
