All -

Attached you will find a copy of the 1.5 version of the Reciprocal  
Public License. This license is an upgrade to the Reciprocal Public  
License, version 1.1, approved in Nov. of 2002 by the OSI.

As stewards of the RPL, used by multiple organizations around the  
world, we take our responsibility very seriously when it comes to  
incorporating feedback from a variety of parties as to license  
improvements. Version 1.5 incorporates a number of improvements  
suggested by both users of the license and the FSF.

Note that a previous upgrade to the RPL, version 1.3, was proposed  
back in April 2006 on this list: 

but no action has been taken thus far.

It is our intent, therefore, to submit version 1.5 which contains  
further changes for approval.

All changes between versions 1.1 and 1.3 can be found on that posting.

All changes between versions 1.3 and 1.5 can be found here:
