This update mostly about visuals:

• Added shadow under character, for better feel how close are you to the ground.
• Improved environment lighting (SSAO).
• Updated player character animations. Subjectively, player movement and position in space feels much better now.
• Added some more skins for player suit / wings / hair.

Also, you can now see changelog in-game (via 'Change Log' menu) to know what's changed since last update.
