\begin{frame}{White Rabbit Switch firmware v6.0}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{itemize}\small
\item Latest firwmare release for WRS-v3 on 12 June 2020 (\textcolor{cyan}{\href{https://ohwr.org/project/wr-switch-sw/wikis/Release-v60}{see}})
\item Highlights:
\begin{itemize}\scriptsize
\item Low phase drift calibration (ports 1-12 only) - improved phase stability between link restarts $<$10ps
\item WRS Low Jitter Daugherboard support
% \item Preamble shrinkage support
% \item Port mirroring to include CPU-originated traffic
\item Leap-second file handling and updating
% \item Kerberos for authentication
\item Reorganized dot-config, more PTP parameters exposed
\item PPSi reorganization to prepare for IEEE1588 HA profile
\item PPSi compatibility with standard PTP improved (BMCA fixed)
\end{itemize}
\item NOTE:
\begin{itemize}\scriptsize
\item dot-config is re-organized, use \textbf{wrs\_menuconfig} to generate configuration
\item it takes much longer to start the WR switch due to calibration, be patient
\end{itemize}
