+- Update to version 13:
+  * Significantly stronger than any of its predecessors:
+    Stockfish 13 outperforms Stockfish 12 by at least 35 Elo
+  * When playing against a one-year-old Stockfish, it wins 60 times
+    more game pairs than it loses
+  * An NNUE network retrained on billions of positions
+  * Much faster network evaluation code
+  * Significantly improved search heuristics
+  * Additional evaluation tweaks
+- Drop update-nnue.patch in favor of the release one
+- Use SourceUrl for nnue
