React Patent RedlineChanges to Facebook's patent grant for React, Flux, Immutable, &c.
After something of a backlash, Facebook revised the separate patent grant for its React software and related libraries.
I’ve converted both versions of the grant to Markdown for easy viewing on GitHub, but the word-diff is still pretty hard to read. Here’s a hand-tuned HTML redline for reference:
Additional Grant of Patent Rights
“Software” means the React software distributed by Facebook, Inc.
youa perpetual, worldwide, royalty-free, non-exclusive, irrevocable (subject to the termination provision below) license under any rights in any patent claims owned by Facebook,to make, have made, use, sell, offer to sell, import, and otherwise transfer the Software.

(i) modifications to the Software made by you or

The license granted hereunder will terminate, automatically and without notice,
