 Python wrappers for libsystemd API
 
+CHANGES WITH 236:
+
+        * Building python-systemd has been modernised and the project now uses
+          pyproject.toml instead of setup.py. Meson has been adopted as the
+          project's build system.
+
+          Note to packagers: meson-python is now a build dependency of
+          python-systemd.
+
+        * The running of tests and building documentation has been integrated
+          with meson.
+
+          Test can be run as
+
+              meson test -C build
+
+          and the documentation can be build with
+
+              meson compile -C build html
+
+        * Support for Python 2 as well as Python 3.7 and 3.8 has been dropped.
+
+        * Various build warnings have been addressed and a fresh build should
+          be clean now.
+
+        * All files use SPDX license headers now.
