Updates in Hero Zero bring new features to the game. Today, the game is updated every 21 days, starting from the update at June 18th, 2013. Before 18/6/2013, the game was updated every 2 weeks (usual). The next update is at June 21st, 2016, but in a special case it can be postponed. It happens 1 or 2 times a month (for 2 times, the first update must happen in 1 to 10 of a month). In the game, the fixing of bugs and new features happen in updates, but there are some updates with only bug fixing.
