+# v1.13.2-aws (2024-12-06)
+
+This release is intended only for use on AWS P* instances. A general release
+that supports other libfabric networks may be made in the near future.
+
+With this release, building with platform-aws requires
+[1.22.0amzn4.0](https://github.com/aws/libfabric/commits/1.22.0amzn4.0/)
+or greater. AWS customers are generally recommended to track
+[the latest-available EFA Installer](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/efa-verify.html)
+for performance improvements and bug fixes.
+
+The 1.13.x release series supports
+[NCCL 2.23.4-1](https://github.com/NVIDIA/nccl/releases/tag/v2.23.4-1)
+while maintaining backward compatibility with older NCCL versions
+([NCCL v2.17.1](https://github.com/NVIDIA/nccl/releases/tag/v2.17.1-1) and later).
+
+Bug Fixes:
+
+  - Tuner Improvements:
+    - Fixed algorithm selection for larger ranks and message sizes.
+    - Re-calibrated the tuner for AllGather and ReduceScatter regions for 0x7 bitmask on P5en,
+    optimizing performance for larger messages.
+    - Added tuner support for AllGather and ReduceScatter regions for 0x0 bitmask on P5en.
+
+  - Resolved a performance issue by preventing the eager protocol when RDMA writes are in flight,
+  improving small AllReduce collective performance.
+
+Note: dmabuf support is now turned off by default. Users can enable it explicitly using OFI_NCCL_DISABLE_DMABUF=0 if needed.
