new paused mode feature (closes #144), controls and progress DOM elements are no longer required in HTML

  font-size: 18pt; instead of fount-size: 22pt;
  remove the "a" tag from def that forces font size, otherwise anchors in various contexts, e.g., headings, etc., will cause ugly rendering due to mismatched font size.
   specify font size for "pre" tags so that code listings more closely match browser rendering

Previously, descenders from characters like 'g' or 'y' were truncated (overflow: hidden)

rm extrenous whitespace

reveal.js was lacking a nice, simple, minimal theme. now it has one.
bam.

the old one was pink. while I don't have anything against pink, I just thought it might be good to make the highlight color dark brown instead.

themes are now available as separate css files under css/theme/, old theme option in config is no longer supported (closes #104)

this way, more browsers are supported, like older Opera/Chrome/FF

this way things are in Impact; Impact fits much more with the visual style than does the default Arial or Calibri.

use mq to reduce font size for low resultions, max limit on width for slides set to 900px (closes #49)
