+As this still represents many git objects to download (163 MB when 4.3 was
+the latest version), if you are using an already downloaded git tree,
+your instructor will probably have fetched the {\em stable} branch ahead
+of time for you too. You can check by running:

+\begin{verbatim}
+git branch -a
+\end{verbatim} 
 
 We will choose a particular stable version in the next labs.
