2018

* Functionality also included in the AutoCAD 2017.1 Update15
The Open option is no longer disabled when you right-click on an unloaded reference in
the External References palette, enabling you to quickly open unloaded reference files.
If you rename an unloaded reference in the External References palette, it no longer
automatically reloads. It remains unloaded until you intentionally reload it.
If you rename an externally referenced file from a tool other than the External References
palette, such as the Xref Manager (CLASSICXREF command) or Rename dialog box, the
new reference name is automatically updated in the Xref palette. You no longer have to
reload it to see the new name.
