Model X update...

Model X update...  I just finished installing a software update.  This one promises to enable some more auto-driving functionality.  Though I read the release notes, it's still not entirely clear to me exactly what was just enabled.  Many of the release notes covered things that were released in the previous release, talking about them as though they were new.  Also, the same language is in there about “calibration” requiring potentially several days of driving before the features are actually enabled.  So ... all I really know is that I just installed an update.  I have no idea what it's going to do, or when. :)
