+# 25.09
+
+ ## Highlights:
+
+  * amrex::callNoinline: Call given function without inline (#4606)
+
+    This new function can be used to force noinlining functions. It can be
+    useful when it's necessary to reduce GPU kernel sizes.
+
+  * Incorrect cross term sum for 2D EB terms in MLEBTensor (#4626)
+
+    This fixes a very old bug in the computation of the cross terms of the
+    Navier-Stokes stress tensor in the 2D EB case. The bug affected AMReX
+    based codes that use the MLEBTensor operator in linear solvers.
+
+  * Add ParallelForOMP (#4595)
+    Fix ParallelForOMP introduced in #4595 (#4604)
+
+    amrex::ParallelFor in CPU builds does not spawn OpenMP threads, because
+    it is usually used inside coarse-grained OpenMP regions launched at the
+    MFIter level. However, in some cases, the users may need to start OpenMP
+    parallel regions in the loops over cells. This new function has been
+    added for this purpose.
+
+  * Add ToString function for array and tuple (#4584)
+
+    This adds a `ToString` function that can be used with scalars, arrays
+    and tuples to write error messages or when debugging.
+
+ ## Other major changes:
+
+  * Delay some synchronize calls in addParticles (#4623)
+    Fix a bug in #4623 (#4631)
+
+  * Fix Bug in FaceConservativeLinear (#4630)
+
+  * Generalize the average_*_to_cellcenter routines to take IntVect (#4627)
+
+  * Fix atomicSetID wrapper access (#4625)
+
+  * Fallback to default `CUDA_ARCH` if `nvidia-smi` fails (#4624)
+
+  * Enable OpenMP in addParticles (#4615)
+
+  * Fix potential false sharing in ReduceOps.eval with OMP (#4618)
+
+  * Enable zero-sized Type in TypeMultiplier (#4617)
+
+  * Add ParamParse::getPrefix (#4612)
+
+  * SIMD: Portable Masks, C++20 (#4607)
+
+  * Improve support for Particles with PolymorphicArenaAllocator (#4603)
+
+  * Improvements to AMREX_ASSERT (#4581)
+
+  * SIMD: Remove Unnecessary Namespaces (#4600)
+
+  * Modify how we interpolate velocity from faces to particle position (#4598)
