Changes

• Adds support for data-auto-animate-restart and data-auto-animate-id. These properties give you finer control over which slides that should auto-animate between each other (@coffeenotfound in #2896).
• Theme properties are now available as CSS variables, making them easy to override. Full list of variables (#2740 + #2968). Here's an example you can drop into your presentation's HTML:

<style type="text/css">
:root {
  --r-background-color: indigo;
  --r-main-color: #f5f5f5;
  --r-main-font: monospace;
}
</style>

Fixes

• Markdown enabled speaker notes (<aside class="notes" data-markdown>) are no longer visible on-slide.
