+From: Victor Stinner <vstinner@python.org>
+Date: Wed, 14 Jan 2026 14:32:40 +0100
+Subject: [PATCH] Update cache_from_source() for Python 3.15
+
+The debug_override parameter of cache_from_source() is deprecated in
+Python 3.14. The function docstring says:
+
+    The debug_override parameter is deprecated. If debug_override
+    is not None, a True value is the same as setting 'optimization'
+    to the empty string while a False value is equivalent to setting
+    'optimization' to '1'.
+
+The parameter has been removed in Python 3.15.
+
+Fixes #255
