+ * Split out worktree module from porcelain into separate ``dulwich.worktree``

+ * Split porcelain module into separate submodules: ``dulwich.porcelain.tags``,
+   ``dulwich.porcelain.notes``, ``dulwich.porcelain.submodule``, and
+   ``dulwich.porcelain.lfs``. Main porcelain module re-exports all functions

+
+ * Ensure ``dulwich.porcelain`` package is properly installed as a directory
+   structure with submodules. (Jelmer Vernooij, #2035)
+
+ * Add tests for consistent license preamble across codebase and prevent
+   ``os.environ`` usage in lower layers. (Jelmer Vernooij, #2033)
+
+ * Add ``__all__`` exports to all modules for better API clarity and wildcard
+   import support. (Jelmer Vernooij, #2022)
+
  * Fix ParamikoSSHVendor interface compatibility with SSHVendor. (Jelmer Vernooij, #2028)
 
+ * Add fallback when HEAD is missing in dumb HTTP protocol, improving
+   compatibility with repositories that don't have a HEAD reference.
+   (Antoine Lambert, #2030)
+
  * Fix smudge filter subprocess fallback for special characters in path.
    (Petr Chmelar, #1878)
 
  * Fix UTF-8 decode error in process filter protocol when handling binary files.

+ * Fix ``porcelain.add()`` to correctly handle ``None`` values in pathspec
+   parameter. (Jelmer Vernooij, #2027)
+
+ * Add ``--stat`` argument to ``dulwich diff`` command to display diffstat
+   summary showing files changed and line additions/deletions. (Jelmer Vernooij, #2026)
+
+ * Avoid signing commits in ``porcelain.stash()`` operations to prevent
+   GPG prompt interruptions during automated stashing. (Jelmer Vernooij, #2012)
+
+ * Improve error handling when trying to remove non-empty directories during
+   worktree operations. (Jelmer Vernooij, #2004)

  * Move greenthreads support to dulwich/contrib.
