WordPress 4.4 has several new features, including:
- a new default theme, Twenty Sixteen, that’s designed to look sharp on all screens, from mobile phones to giant desktop displays
- responsive images so WordPress shows images at the right size for each device (potentially abbreviating page loads)
- embeddable WordPress content, so your content can be shared more gracefully across sites that support consuming oEmbed data
- more support for embedding outside content, like Speaker Deck and Reddit comments
