+
+  -- Make CreateVirtualParticles use GPU functions for aggregation_type=None
+     (#2195)
+
+  -- Change mask for ctr to ctroid interp (#2196)

+
+  -- Introduction of the experimental parfor into NodeLaplacian
+     interpolation (#2183)
+
+  -- Enable default construction for AmrParticleContainer and add
+     isDefined() method. (#2188) A Particle container is considered
+     "defined" if it has been given a set of grids, otherwise not.
+
+  -- Make CreateGhostParticles use GPU functions (#2185)
+
+  -- Add ROCMClang as an LLVM compiler to cmake (#2184)
+
+  -- Scale uniform random interval to account for gridbox length in
+     ParticleInit (#2179)

+  -- Gradient in WarpX EB nodal solver (#2171)
+
+  -- Update MacProjector::project to check if m_umac is nullptr (#2166)
+
+  -- EB nodal solver (#2145) New EB nodal solver with Dirichlet EB.  This
+     uses a finite-difference stencil.  It will be used by WarpX's static
+     solver.
+
+  -- Workaround for a DPC++ reduction issue (#2165)
+     More reliable workaround for DPCPP reduction issue (#2167)

+  -- IParser: Integer Parser (#2158)
+
+  -- Disable `jn` in Parser on Windows (#2152)
