No more “Standard” theme out of the box with Moodle 2.7, Bootstrap based “Clean” theme will now be the default theme of new Moodle installations (giving your site responsiveness from the 1st moment it hits the web).
There are some interesting navigation items in the mix for Clean as well which you can test out (and test our the theme at the same time) which we’ve highlighted before. Check out Clean theme before it becomes the default theme at http://prototype.moodle.net/clean/.
Interested on what else is coming up for Moodle? It’s always worth glancing at the weekly Integration report from Moodle HQ: https://moodle.org/mod/forum/discuss.php?d=254823&parent=1105255
