are a number of other noteworthy changes in the current \dealii{} release
that we briefly outline in the remainder of this section:

\label{subsec:particles}
\dealii 's particle infrastructure has been modernized to store nearly all
-particle data as a set of continuous data arrays instead of a container of
+particle data as a collection of continuous data arrays instead of a container of
objects. This reorganization improves cache efficiency when iterating over
particles and reduces the amount of data that needs to be moved when a particle
moves to a different cell. Keeping track of unused data slots allows to reuse
them for new particles, significantly reducing memory allocations when
particles are created after other particles have left the local domain. The
-data arrays are rebuild and sorted during every mesh refinement cycle.

+Additionally, the particle infrastructure now supports a faster search algorithm
for particles that moved farther than one cell width between particle sorting
operations, and support for updating ghost particles (particles that live in
ghost cells around the local domain) by updating their properties instead of
-destroying and rebuilding their container was added, which improves the
+destroying and rebuilding their container. The latter step improves the
efficiency of ghost particle exchange significantly.
-Finally the \texttt{Particles::DataOut} class now supports writing particle
-properties as vectors or tensors instead of scalars if the properties are
