WordPress/wp-admin/js/revisions.min.js
Bot (Assets) 6e798324e9 New develop.svn.wordpress.org repository based on the old core.svn repository. 
* All WordPress files move to a src/ directory.
 * New task runner (Grunt), configured to copy a built WordPress to build/.
 * svn:ignore and .gitignore for Gruntfile.js, wp-config.php, and node.js.
 * Remove Akismet external from develop.svn. Still exists in core.svn.
 * Drop minified files from src/. The build process will now generate these.

props koop.
