+# 25.11
+
+ ## Highlights:
+
+  * AMReX is now compatible with oneAPI 2025.03 that has deprecated a number
+    of things such as the `fsycl-device-lib` flag and the
+    `mkl::sparse::set_csr_data` function.
+
+  * It used to be an assertion error when the number of ghost cells in the
+    MultiFab is different from that in the VisMF file. We now allow them to
+    be different. Note that if there are more ghost cells in the MultiFab,
+    the extra ghost cell regions are not filled.
+
+  * In `amrex::UtilCreateCleanDirectory`, if a directory already exists, we
+    preserve it by renaming it to a directory whose name includes a string
+    generated by `amrex::UniqueString()`. However, this string is not
+    guaranteed to be unique. The behavior of `std::rename` is
+    implementation-defined, and it may fail if the destination already
+    exists. This happens rarely, but it does happen. We now addresse the
+    issue by removing the existing conflicting directory before
+    renaming. This makes the file renaming process more robust.
+
+  * We have reimplemented SumBoundary. In the old approach, we make a
+    temporary copy of the data, zero out the original data, and then perform
+    parallel add. In the new approach that should be more efficient, we no
+    longer need a temporary copy of the entire data. We have also added an
+    optional argument that can be used to make SumBoundary
+    deterministic. Note that being deterministic does not mean the data are
+    consistent on shared nodes. For that, one still needs to call
+    OverrideSync, or FillBounaryAndSync.
