Removing the last bullet from the top navigation bar

Question

I wish to remove the bullet corresponding to the last slide of my presentation from the top navigation bar, like this:

To that end, I've attempted to use an empty section \section{} as recommended in this thread.

MCVE

\documentclass[handout]{beamer}
\usetheme[compress]{Singapore}

\begin{document}

    \begin{frame}[plain]
        \titlepage
    \end{frame}

    \begin{frame}{Introduction}
    \end{frame}

    \section{Section 1}
    \begin{frame}{Slide 1a}    
    \end{frame}
    \begin{frame}{Slide 1b}    
    \end{frame}

    \section{Section 2}
    \begin{frame}{Slide 2a}    
    \end{frame}
    \begin{frame}{Slide 2b}    
    \end{frame}

    \section{}
    \begin{frame}{Recapitulation}
    \end{frame}

\end{document}

But the unwanted bullet is still there:

How could I get around this?

Edit: The header would still be "focused" on the "section 2" text. To prevent this, I added \section*{} right after \bulletoff.

The "bullet system" is called miniframes, and are generated via a .nav file. The command responsible for writing to that file is the \beamer@writeslidentry. We can make this do nothing for a temporary amount of time:

\makeatletter
% Remember the way beamer did it before
\let\beamer@old@writeslidentry\beamer@writeslidentry
% Tell it to do nothing with the slides entry
\newcommand\bulletoff{\let\beamer@writeslidentry\relax}
% Reset it to the old ways
\newcommand\bulleton{\let\beamer@writeslidentry\beamer@old@writeslidentry}
\makeatother

Your entire code becomes then

\documentclass[handout]{beamer}
\usetheme[compress]{Singapore}
\begin{document}
    \makeatletter
    % Remember the way beamer did it before
    \let\beamer@old@writeslidentry\beamer@writeslidentry
    % Tell it to do nothing with the slides entry
    \newcommand\bulletoff{\let\beamer@writeslidentry\relax}
    % Reset it to the old ways
    \newcommand\bulleton{\let\beamer@writeslidentry\beamer@old@writeslidentry}
  \makeatother
    \begin{frame}[plain]
        \titlepage
    \end{frame}

    \begin{frame}{Introduction}
    \end{frame}

    \section{Section 1}
     \begin{frame}{Slide 1a}
     \end{frame}
     \begin{frame}{Slide 1b}
     \end{frame}

    \section{Section 2}
     \begin{frame}{Slide 2a}
     \end{frame}
     \begin{frame}{Slide 2b}
     \end{frame}

     \bulletoff\section*{}
     \begin{frame}{Recapitulation}
      No bullet here :)
     \end{frame}
\end{document}

This produces exactly the image you presented:

Note that if you use the \bulleton command, it will behave differently if you do \clearpage prior to it. If you don't do \clearpage the bullet will be filled.
