+# 20.10
+
+  -- CMake: fix ENABLE_PROFPARSER and ENABLE_SENSEI options (#1428)
+
+  -- Remove EB LSCore and levelset, and reimplement signed distance function
+     capability. (#1429 & #1425)
+
+  -- Remove flags setCGVerbose and setCGMaxIter since those are more
+     accurately called setBottomVerbose and setBottomMaxIter.  The
+     "setCG..."  flags are misleading since they actually apply to non-CG
+     bottom solvers as well. (#1413)
+
+  -- Remove GetPosition and SetPosition from ParIter.  These were added for
+     WarpX, but they are not used any more. (#1408)
+
+  -- Only check the requested MPI Threading level if AMReX also initialized
+     MPI. (#1406)
+
+  -- DPCPP support for mulitple GPUs (#1392)
+
+  -- Random Number Generation on Device (#1363) In order to support RNG on
+     device with DPC++, we have to change the API because DPC++ does not
+     support global device variables.
+
+  -- Remove redundant particle tests and old/obsolete/non-test tests (#1389
+     & #1381)
+
+  -- Gpu kernel fusing is integrated in MFIter. (#1332)
+
+  -- New runtime parameter, amrex.max_gpu_streams. (#1386)
+
+  -- Switch to `use mpi` from `include 'mpif.h'` (#1385)
+
+  -- Remove reliance on managed memory from
+     AMReX_ParticleCommunication.H/.cpp (#1380)
+
+  -- CMake: re-organize tutorials (#1333)
+
+  -- Implement Particle in a way that does not involve UB. (#1337)
+
+  -- amrex::EB_average_down(): Fix indexing error. (#1360)
+
+  -- Only add one copy of the ghost particle regardless of how many isects
+     we have (#1359)
+
+  -- Add non-EB slopes and extend the generality of EB slope routines in 2D
+     and 3D (#1350)
+
+  -- Async IO: Check Runtime Threading (#1351)
+
+  -- Changes to make AMR codes compiled with EB but not building any
+     Geometry work as if it is all regular. (#1349)
+
+  -- Fix mkconfig.py (#1344)
+
+  -- Add -Xcudafe --diag_suppress=esa_on_defaulted_function_ignored to
+     suppress spurious warnings from nvcc. (#1342)
+
+  -- EB extend_domain_face (#1321)
+
+  -- Add parameter that stores OpenMP support version (#1325)
+
 # 20.09
 
   -- Fix interpolation coefficients for EB stencil in cell-centered linear
