   change: |
     Enable obsolete line folding in BalsaParser (for behavior parity with http-parser, the
     previously used HTTP/1 parser).
+- area: http3
+  change: |
+    Use GRO (Generic Receive Offload) for reading packets from a UDP socket. See
+    https://www.kernel.org/doc/html/next/networking/segmentation-offloads.html for a description of
+    GRO. This behavior change can be reverted by setting
+    ``envoy.reloadable_features.prefer_udp_gro`` to ``false``.
