 Python wrappers for libsystemd API
 
+CHANGES WITH 236:
+
+        * Meson setup was adjusted to avoid hard failing when
+          libsystemd development files are not available. On
+          unsupported/non-Linux environments, extension modules are
+          skipped, which allows metadata generation, source
+          distribution builds, and dependency lock resolution in
+          cross-platform environments.
+
+        * Build logs now include a clear warning when libsystemd
+          development files are missing and native extension modules
+          are skipped.
+
 CHANGES WITH 235:
 
         * Adapt the rename of systemd-activate to systemd-socket-activate

 To build from source
 --------------------
 
+Metadata generation and dependency resolution (for example `uv lock`,
+Poetry, and pip-tools) do not require native `libsystemd` development files.
+Those native dependencies are only required when building/installing extension
+modules from source.
+
 On CentOS, RHEL, and Fedora:
 
     dnf install git python3-pip gcc python3-devel systemd-devel
