0.6 brings a brand new game mode, Drop Four (also known as Connect Four, Captain’s Mistress, Four Up, Plot Four, Find Four, Four in a Row, Four in a Line and Gravitrips). I’ll add more information about this in a game design post. Other features include:

• Browsable release notes in app, that include links to the blog.
• Back and forward buttons in the game history.
• In game action buttons now use icons.
• Previous move highlight now fills the square.
