The Aug 2009 version of Streetview for Luz has been replaced by a version taken in Feb 2015. This makes it nearly 8 years out of date re Madeleine's disappearance.
The Luz map has been updated. Some establishments which existed at the time but have ceased trading have been removed. Some which were not trading at the time have been added.
The streets mapped by Google seem to have changed too, with some gains and some losses. For example, it is now possible to explore down the front of the church to the Fortaleza and then along to the start of the promenade.
Obviously, there has been a turnover of establishments. On my blog, the example I took was the Cave Bar, (definitely open in May 2007), which became Jake's Restaurant, which in turn became Rio's. The one appearing in the Feb 2015 version is Rio's, though that has closed recently.
I would have thought Streetview of Aug 2009 was valuable to Operation Grange. Of course, this could be wrong. Or it could be that everything they want has been secured already, or that they can regain access to the 2009 version.
I have tried digging the old version out of the Wayback Machine, without success. If anyone can do better, please let us know.
All in all, it would appear that any copies of the Aug 2009 scenes that have been secured by armchair detectives may have increased in worth as a result of this change. So look after any you might have in your files.
