Geometry Dash World is a free ad-supported expansion app of Geometry Dash developed and published by RobTop Games and released on December 21, 2016 for iOS and on December 22, 2016 for Android. It features ten exclusive short levels which must be played in sequence, split into two worlds containing five levels each. The game is a downsized build of the full version of Geometry Dash and was released just prior to Update 2.1 (allowing much new content to be previewed). Hence, other current content at the time including achievements, icons, collectibles, shops and vaults are available although limited. Everyplay and the ability to transfer certain unlockable data over to the full version through user accounts are also available. In addition, certain user levels can be played, either the daily level or featured levels once the main levels have been completed.
The following table contains the official update information provided in the iOS App Store, only omitting secondary information such as support notices.

Lots of new things to find!
Bugfixes and tweaks
Some days before 2.1 came, an exploit to get to the level editor has been found: Load an account with a copyable level, then copy it and get to the editor. This exploit was a major discovery, since it had 2.1 items depsite the update wasen't released. By the game release time, it had been fixed. However, after 2.1 came, the change reverted and the bug can be done again. Oddly, it now contains unfinished 2.2 triggers, likely done by copying SubZero's data to update to iPhone X support.
