 \begin{itemize}
 \item Sampling frequencies up to 1\,kHz.
-\item Supports only single-tasking single rate and multi rates systems. Support
-  for multitasking systems will be available in the final version and will require careful audit
-  of the RPP library with respect to thread-safe code.
+\item Multi-rate models are executed in a single thread in
+  non-preemptive manner. Support for multi-threaded execution will be
+  available in the final version and will require careful audit of the
+  RPP library with respect to thread-safe code.
 \item No External mode support yet. We work on it.
 \item Custom compiler options, available via OPTS variable in
   \emph{Make command} at \emph{Code Generation} tab (see Figure
