==MPL 2 Upgrade FAQ==

====What's this about?=Introduction===

Mozilla has now completed a 21-month process to revise the Mozilla Public License (MPL), the licence it has used for most new code since the original release of the source code in 1998. The result is a licence which is about half the length, has many provisions removed which have become onerous to comply with, and has better compatibility with other licences.

We would run it against the following repositories:
