should not be visible to typical user codes; some remove previously
deprecated classes and functions; and the majority change internal
interfaces that are not usually used in external
-applications. However, some are worth mentioning:
+applications. That said, the following are worth mentioning since they
+may have been more widely used:
\begin{itemize}
\item Two functions that provide information about all processes,
namely
stores information for all processes on all processes, but only
local or locally-relevant information. On the other
hand, if necessary, global information can still be computed using,
-for example, calling \texttt{Utilities::MPI::Allgather(locally\_owned\_info(), comm)}.
-\item
- \todo[inline]{What else is worth mentioning? Someone needs to go
- through the list of incompatible changes...}
+for example, calling
+\texttt{Utilities::MPI::Allgather(locally\_owned\_info(), comm)}.
+
+\item A corresponding change has been made in parallel triangulation
+ classes:
+ \texttt{parallel::} \texttt{TriangulationBase::compute\_n\_locally\_owned\_active\_cells\_per\_processor()}
+ can be used to obtain information about how many cells each
+ process owns.
