0.24.7	2025-10-23

 * Add sparse index support for improved performance with large repositories.
   Implements reading and writing of sparse directory entries, index expansion/
   collapse operations, and the 'sdir' extension.
   (Jelmer Vernooĳ, #1797)

 * Add support for core.fsyncObjectFiles configuration option.
   (Jelmer Vernooĳ, #1817)

 * Work around typing module bug in Python 3.9.0 and 3.9.1 by using string
   annotation for Callable type in reflog.py. (Jelmer Vernooĳ, #1948)

   vendor. Regression from 0.24.2.  (Jelmer Vernooĳ, #1945)

 * Fix LFS URL validation to prevent DNS resolution errors when ``lfs.url`` is
   configured with an invalid value. Implement full support for ``file://`` URLs
   to access local LFS repositories, matching git-lfs behavior.
   (Jelmer Vernooĳ, #1951)

0.24.6	2025-10-19

 * Fix import failure when ``sys.stdin`` is ``None``. The ``dulwich.server``
   module can now be imported in environments where ``sys.stdin`` is ``None``,
   such as Windows GUI apps, apps started with ``pythonw``, or apps using
   ``ProcessPoolExecutor``. (Jelmer Vernooĳ, #1939)

 * Add support for ``dulwich reflog expire`` and ``dulwich reflog delete`` commands.
   (Jelmer Vernooĳ, #1798)

 * Add ``dulwich cherry`` command to find commits not merged upstream.
   Compares commits by patch ID to identify equivalent patches regardless of
   commit metadata. Supports automatic upstream detection from tracking branches
   and verbose mode to display commit messages. (Jelmer Vernooĳ, #1782)

 * Add support for ``git mailsplit`` command to split mbox files and Maildir
   into individual message files. Supports mboxrd format, custom precision,
   and all standard git mailsplit options. (Jelmer Vernooĳ, #1840)

 * Implement recursive merge strategy for handling multiple merge bases
   (criss-cross merges). When multiple common ancestors exist, the algorithm
   creates a virtual merge base by recursively merging them, reducing false
   conflicts in complex merge scenarios. The recursive strategy is now used
   automatically by ``porcelain.merge()``. (Jelmer Vernooĳ, #1815)

 * Add support for ``dulwich show-branch`` command to display branches and their
   commits. Supports filtering by local/remote branches, topological ordering,
   list mode, independent branch detection, and merge base calculation.
   (Jelmer Vernooĳ, #1829)

 * Add ``dulwich config`` command to get and set repository or global
   configuration options. Supports getting/setting values, listing all config,
   getting all values for multivars, and unsetting values.
   (Jelmer Vernooĳ, #1775)

0.24.5	2025-10-15

 * Add support for ``dulwich show-ref`` command to list references in a local
   repository. Supports filtering by branches/tags, pattern matching,
   dereferencing tags, verification mode, and existence checking. Available
   as ``porcelain.show_ref()`` and ``dulwich show-ref`` CLI command.
   (Jelmer Vernooĳ, #1830)

 * Fix HTTP authentication to preserve credentials from URLs when storing
   remote configuration. URLs with embedded credentials (like
   ``https://token@github.com/user/repo.git``) now correctly save those
   credentials to git config, allowing subsequent push operations to succeed.
   (Jelmer Vernooĳ, #1925)

 * Restore ``pool_manager`` parameter to ``get_transport_and_path`` and
   ``get_transport_and_path_from_url`` functions that was accidentally removed
   during type annotation refactoring. (Jelmer Vernooĳ, #1928)

0.24.4	2025-10-14

 * Add support for ``dulwich var`` command to display Git's logical variables
   (GIT_AUTHOR_IDENT, GIT_COMMITTER_IDENT, GIT_EDITOR, GIT_SEQUENCE_EDITOR,
   GIT_PAGER, GIT_DEFAULT_BRANCH). Available as ``porcelain.var()`` and
   ``dulwich var`` CLI command. (Jelmer Vernooĳ, #1841)

 * Add support for ``GIT_TRACE`` environment variable for debugging. Supports
   output to stderr (values "1", "2", or "true"), file descriptors (3-9),
   file paths, and directories (creates per-process trace files).
   (Jelmer Vernooĳ, #1863)

 * Add ``extract_signature()`` method to ``Commit`` and ``Tag`` classes that
   returns (payload, signature, signature_type) tuple. Supports both PGP and SSH
   signature detection. (Jelmer Vernooĳ)

 * Fix Git filter protocol implementation to properly handle the two-phase
   response format (initial headers, content, final headers) as specified in
   the Git protocol documentation. This fixes compatibility with Git LFS and
   other filters that send status messages in final headers.
   (Jelmer Vernooĳ, #1889)

 * Add ``dulwich worktree repair`` command to repair worktree administrative files
   after worktrees or the main repository have been moved.
   (Jelmer Vernooĳ, #1799)

 * Add ``dulwich verify-tag`` command to check GPG signatures of tags.
   (Jelmer Vernooĳ, #1833)

 * Add ``dulwich verify-commit`` command to check GPG signatures of tags.
   (Jelmer Vernooĳ, #1832)

0.24.2	2025-09-25

 * Added ``porcelain.shortlog`` function to summarize commits by author,
   similar to git shortlog. (Muhammad Usama, #1693)

 * Fix merge functionality to gracefully handle missing optional merge3 dependency
   by raising informative ImportError with installation instructions.
   (Jelmer Vernooĳ, #1759)

 * Fix worktree CLI tests to properly change to repository directory.
   (Jelmer Vernooĳ, #1738)

 * Add ``temporary_worktree`` context manager for creating temporary worktrees
   that are automatically cleaned up. (Jelmer Vernooĳ)

 * Add ``exist_ok`` parameter to ``add_worktree`` to allow creation with
   existing directories. (Jelmer Vernooĳ)

 * Add colorized diff support for the ``show`` command with ``--color``
   argument. (Jelmer Vernooĳ, #1741)

 * Fix Windows path handling in ``_ensure_parent_dir_exists`` to correctly
   handle drive letters during checkout operations. (Jelmer Vernooĳ, #1751)

 * Fix Windows config loading to only use current Git config path,
   avoiding loading older config files.  (Jelmer Vernooĳ, #1732)

 * Add interactive rebase support with ``dulwich rebase -i``, including support
   for pick, reword, edit, squash, fixup, drop, exec, and break commands.
   (Jelmer Vernooĳ, #1696)

 * Fix handling of CRLF line endings with ``core.autocrlf = input`` to prevent
   unchanged files from appearing as unstaged in status.
   (Jelmer Vernooĳ, #1773)

 * Add support for ``core.whitespace`` configuration for whitespace error
   detection and fixing. Supports blank-at-eol, space-before-tab, indent-with-non-tab,
   tab-in-indent, blank-at-eof, cr-at-eol, and tabwidth settings.
   (Jelmer Vernooĳ, #1806)

 * Add support for ``core.safecrlf`` configuration to check if CRLF/LF conversions
   would be reversible and optionally abort or warn on potentially lossy conversions.
   (Jelmer Vernooĳ, #1806)

 * Add support for ``http.extraHeader`` configuration to pass additional HTTP
   headers to the server when communicating over HTTP(S).
   (Jelmer Vernooĳ, #1769)

 * Optimize LFS filter performance by avoiding redundant disk writes when
   checking file status. The LFS store now checks if objects already exist
   before writing them to disk, significantly improving ``dulwich status``
   performance in repositories with many LFS-tracked files.
   (Jelmer Vernooĳ, #1789)

 * Add filter server support. (Jelmer Vernooĳ, #1789)

 * Add support for ``patiencediff`` algorithm in diff.
   (Jelmer Vernooĳ, #1795)

 * Add IPv6 support for git:// protocol URLs.
   (Jelmer Vernooĳ, #1796)

 * Add support for ``core.preloadIndex`` configuration setting to enable
   parallel stat operations when checking for unstaged changes. This improves
   performance on slow filesystems like NFS. (Jelmer Vernooĳ, #1851)

0.24.1	2025-08-01

 * Require ``typing_extensions`` on Python 3.10.
   (Jelmer Vernooĳ, #1735)

0.24.0	2025-08-01

 * Add comprehensive git worktree support including ``WorkTreeContainer``
   class, ``WorkTreeInfo`` objects, and full CLI/porcelain implementations
   for add, list, remove, prune, lock, unlock, and move operations.
   (Jelmer Vernooĳ, #1710, #1632)

 * Add support for ``-a`` argument to
   ``dulwich.cli.commit``. (Jelmer Vernooĳ)

   ``dulwich.cli.commit`` and ``dulwich.porcelain.commit``. (Jelmer Vernooĳ)

 * Add support for merge drivers.
   (Jelmer Vernooĳ)

 * Add support for Git revision syntax operators ``~``, ``^``, ``^{}``,
   ``@{N}``, and ``:path`` in ``dulwich.objectspec.parse_object``,
   e.g. ``HEAD~1``, ``HEAD^2``, ``v1.0^{}``, ``HEAD@{1}``, ``HEAD:README``.
   (Jelmer Vernooĳ)

 * Add support for ``GIT_CONFIG_GLOBAL`` and ``GIT_CONFIG_SYSTEM``
   environment variables to override global and system configuration
   paths. (Jelmer Vernooĳ, #1193)

 * ``dulwich.porcelain.diff``: Support diffing two commits
   and diffing cached and working tree. (Jelmer Vernooĳ)

 * Add ``format-patch`` command in porcelain. (Jelmer Vernooĳ)

 * Add functions for creating bundles and ``BundleClient``
   for interacting with bundles. (Jelmer Vernooĳ, #1246)

   whether commit-graph files are used for performance optimization.
   (Jelmer Vernooĳ)

 * Add ``reflog`` command in porcelain. (Jelmer Vernooĳ)

 * Add ``locked_ref`` context manager for atomic ref operations.
   (Jelmer Vernooĳ)

 * Fix bug in ``DiskRefsContainer._remove_packed_ref`` that prevented
   packed ref deletions from being persisted to disk.
   (Jelmer Vernooĳ)

 * Optimize writing unchanged refs by avoiding unnecessary fsync
   when ref already has the desired value. File locking behavior
   is preserved to ensure proper concurrency control.
   (Dan Villiom Podlaski Christiansen, Jelmer Vernooĳ, #1120)

 * Fix Unicode filename encoding issue on Windows where non-ASCII
   filenames were corrupted during clone/checkout operations.
   (Jelmer Vernooĳ, #203)

0.23.2	2025-07-07

 * Print deprecations on usage, not import.
   (Alyssa Coghlan, #1650)

 * Add support for ``core.protectHFS`` configuration setting to protect
   against paths that could be misinterpreted on HFS+ filesystems.
   (Jelmer Vernooĳ, #246)

 * Only write Git index extensions when they contain meaningful data.
   Previously, dulwich would write empty extensions to the index file,
   causing unnecessary bloat.
   (Andrew Shadura, Jelmer Vernooĳ, #1643)

 * Document that ``porcelain.push`` returns per-ref status information
   in the ``SendPackResult`` object. Added test coverage to verify this
   functionality works as expected.
   (Jelmer Vernooĳ, #780)

 * Add porcelain submodule commands: ``submodule_update``, ``submodule_add``g
   CLI command, and ``submodule_update`` CLI command. Add ``--recurse-submodules``
   option to ``clone`` command. (#506, Jelmer Vernooĳ)

 * Support popping stashes. (Jelmer Vernooĳ)

 * Add support for parsing Git attributes from .gitattributes files.
   This enables proper handling of text/binary detection, line ending
   normalization, and filter specifications for files.
   (Jelmer Vernooĳ, #1211)

 * Add git bisect functionality including core bisect logic, porcelain
   commands (bisect_start, bisect_bad, bisect_good, bisect_skip,
   bisect_reset, bisect_log, bisect_replay), and CLI support.
   (Jelmer Vernooĳ, #1631)

 * Fix ``porcelain.describe()`` to dynamically determine hash length
   based on uniqueness, matching git describe behavior more closely.
   Previously used a hardcoded 7-character hash length.
   (Jelmer Vernooĳ, #824)

 * Add test for ``porcelain.add()`` to verify files can be added when
   the current working directory is within a gitignored directory.
   (Jelmer Vernooĳ, #550)

 * ParamikoSSHVendor now reads SSH configuration from ~/.ssh/config.
   Host settings including hostname, user, port, and identity file are
   now respected when establishing SSH connections.
   (Jelmer Vernooĳ, #443)

0.23.1	2025-06-30

 * Support ``untracked_files="normal"`` argument to ``porcelain.status``,
   and make this the default.
   (Jelmer Vernooĳ, #835)

 * Fix ``parse_commit`` to properly dereference annotated tags when
   checking out tags. Previously, checking out an annotated tag would
   fail with a KeyError.
   (Jelmer Vernooĳ, #1638)

 * Handle different file type transitions properly in ``update_working_tree``
   (Jelmer Vernooĳ, #1638)

 * Fix KeyError when pulling from a shallow clone. Handle missing commits
   gracefully in graph traversal operations for shallow repositories.
   (Jelmer Vernooĳ, #813)

 * Return symrefs from ls_refs. (Jelmer Vernooĳ, #863)

 * Support short commit hashes in ``porcelain.reset()``.
   (Jelmer Vernooĳ, #1154)

   (Jelmer Vernooĳ, #1097)

 * Fix TypeError when cloning repositories with bytes paths on Windows.
   (Jelmer Vernooĳ, #973)

 * Support ``depth`` for local clones.
   (Jelmer Vernooĳ)

 * Add basic support for managing Notes. (Jelmer Vernooĳ)

 * Add basic ``cherry-pick`` subcommand.  (#1599, Jelmer Vernooĳ)

 * Add ``revert`` command to ``dulwich.porcelain`` and CLI.
   (#1599, Jelmer Vernooĳ)

 * Add annotate support as well as ``annotate`` and ``blame``
   commands.  (#245, Jelmer Vernooĳ)

 * Fix ``apply_delta`` to raise ``ApplyDeltaError`` instead of ``AssertionError``
   when the source buffer size doesn't match the delta header. This issue only
   affected the pure Python implementation when the Rust extension was not
   available. The Rust implementation already raised the correct exception.
   (#1606, Jelmer Vernooĳ)

 * Fix ``porcelain.reset --hard`` to properly delete files that don't exist in
   the target tree. Previously, when resetting to a remote branch, files deleted
   in the remote were not removed locally due to incorrect path normalization
   on Windows. (#840, Jelmer Vernooĳ)

 * Add support for includes in configuration files.
   (#1216, Jelmer Vernooĳ)

 * Support timeouts for HTTP client operations.  (Jelmer Vernooĳ)

 * Add support for ``reset --mixed`` and ``reset --soft`` modes in
   ``porcelain.reset()`` and the CLI. Mixed reset updates HEAD and index
   but leaves working tree unchanged. Soft reset only updates HEAD.
   (Jelmer Vernooĳ)

 * Apply line-ending normalization in ``build_index_from_tree`` to respect
   ``core.autocrlf`` configuration during checkout operations.
   (Jelmer Vernooĳ, #663)

 * Add ``prune`` method to object stores for cleaning up orphaned temporary
   pack files. This is now called by ``garbage_collect()`` to match Git's
   behavior. Also added ``prune`` command to ``dulwich.porcelain``.
   (Jelmer Vernooĳ, #558)

 * Fix ``porcelain.remove()`` to work correctly when called from a directory
   other than the repository root. Relative paths are now interpreted as
   relative to the repository root rather than the current working directory.
   (Jelmer Vernooĳ, #821)

 * Add support for auto garbage collection, and invoke from
   some porcelain commands. (Jelmer Vernooĳ, #1600)

 * Add ``filter-branch`` support to ``dulwich.porcelain`` and
   ``dulwich.filter_branch`` module for rewriting commit history.
   Supports filtering author, committer, and message fields.
   (#745, Jelmer Vernooĳ)

 * Add ``mv`` porcelain command. (Jelmer Vernooĳ, #1633)

0.23.0	2025-06-21

 * Add basic ``rebase`` subcommand. (Jelmer Vernooĳ)

 * Add ``gc`` command to ``dulwich.porcelain.`` (Jelmer Vernooĳ, #92)

 * Add ``unpack-objects`` plumbing command to unpack objects from pack files
   into loose objects in the repository. This command extracts all objects
   from a pack file and writes them to the object store as individual files.
   Available in both ``dulwich.porcelain.unpack_objects()`` and as a CLI
   command ``dulwich unpack-objects``. (Jelmer Vernooĳ)

 * Add ``merge-tree`` plumbing command to ``dulwich.porcelain`` and CLI.
   This command performs three-way tree merges without touching the working
   directory or creating commits, similar to ``git merge-tree``. It outputs
   the merged tree SHA and lists any conflicted paths. (Jelmer Vernooĳ)

 * Add ``porcelain.count_objects()`` function to count unpacked objects and
   their disk usage. Returns a tuple of (count, size) for simple usage or
   a ``CountObjectsResult`` dataclass with detailed statistics when
   ``verbose=True``. (Jelmer Vernooĳ)

 * Add support for pack index format version 3. This format supports variable
   hash sizes to enable future SHA-256 support. The implementation includes
   reading and writing v3 indexes with proper hash algorithm identification
   (1 for SHA-1, 2 for SHA-256). Note that SHA-256 support itself is not yet
   implemented and will raise NotImplementedError. (Jelmer Vernooĳ)

 * Fix ``LocalGitClient`` assertion error when fetching externally cloned repositories
   into ``MemoryRepo``. Previously, the client would fail with an AssertionError
   when trying to process pack data from repositories that were cloned externally.
   (Jelmer Vernooĳ, #1179)

 * Add support for ``os.PathLike`` objects throughout the API. Functions that
   accept file paths now support ``pathlib.Path`` objects in addition to
   strings and bytes. This includes repository operations, configuration file
   handling, ignore file processing, and all major entry points.
   (Jelmer Vernooĳ, #1074)

 * Add support for ``format`` argument to ``Repo.init()`` and ``Repo.init_bare()``
   to specify repository format version (0 or 1). This allows creating repositories
   with different format versions by setting the ``core.repositoryformatversion``
   configuration value. (Jelmer Vernooĳ)

 * Fix Rust implementation of ``sorted_tree_items()`` to correctly handle submodules.
   Previously, submodules (mode 0o160000) were incorrectly treated as directories
   in the sorting order, causing different results compared to the Python
   implementation. (Jelmer Vernooĳ, #1325)

 * Fix ``porcelain.add()`` to stage both untracked and modified files when no
   paths are specified. Previously, only untracked files were staged, inconsistent
   with Git's behavior. Now behaves like ``git add -A`` when called without paths.
   (Jelmer Vernooĳ, #746)

 * Fix ``porcelain.add()`` symlink handling to allow adding symlinks that point
   outside the repository. Previously, the function would fail when trying to
   add a symlink pointing outside the repo due to aggressive path resolution.
   Now only resolves the parent directory for symlinks, matching Git's behavior.
   (Jelmer Vernooĳ, #789)

 * Fix ``porcelain.add()`` when adding repository root path or directories.
   Previously, adding the repository path itself would incorrectly stage
   ``b'./'`` instead of the actual untracked files, leading to
   repository corruption.  (Jelmer Vernooĳ, #1178, #655)

 * Improve ``porcelain.add()`` documentation to correctly describe default
   behavior. (Jelmer Vernooĳ, #895)

 * Fix gitignore pattern matching for directory negation patterns. Patterns like
   ``!data/*/`` now correctly unignore direct subdirectories while still ignoring
   files in the parent directory, matching Git's behavior. The ``is_ignored()`` method
   now documents that directory paths should end with ``/`` for consistent behavior.
   (Jelmer Vernooĳ, #1203)

 * Support quote_path flag for ignore checking. (Jelmer Vernooĳ)

 * Clarify documentation for ``IgnoreFilter`` and ``IgnoreFilterManager`` to
   explicitly state that directory paths should include trailing slashes when
   checking if they are ignored. This matches Git's behavior and ensures
   consistent results. (Jelmer Vernooĳ, #972)

 * Add support for Git's ``feature.manyFiles`` configuration and index version 4.
   This enables faster Git operations in large repositories through path prefix
   compression (30-50% smaller index files) and optional hash skipping for faster
   writes. Supports ``feature.manyFiles``, ``index.version``, and ``index.skipHash``
   configuration options.
   (Jelmer Vernooĳ, #1061, #1462)

 * In dulwich.porcelain docstring, list functions by their Python identifiers.
   (Marnanel Thurman)

 * cli: add basic branch management commands (James Addison, #1514)

 * Fix wheels workflow. (Jelmer Vernooĳ)

   appends them. (Jelmer Vernooĳ, #1545)

 * Support ``core.sshCommand`` setting.
   (Jelmer Vernooĳ, #1548)

 * Bump PyO3 to 0.25. (Jelmer Vernooĳ)

   arguments in client. (Jelmer Vernooĳ)

 * Strip pkt-line when negotiating protocol v2. Fixes
   compatibility with gerrit. (Rémy Pecqueur, #1423)

 * Don't pull in ``setuptools_rust`` when building pure
   package. (Eli Schwartz)

 * Return peeled refs from ``GitClient.get_refs`` if protocol-v2
   is used. (Stefan Sperling, #1410)

 * Drop outdated performance file. (Jelmer Vernooĳ, #1411)
