Trivia

Blast Processing's trailer had some decoration changes from the final version.
This update did not include any new map packs, making it the first update to do so after Update 1.6 added the first map packs.
The song Theory of Everything 2 was a collaboration with DJ-Nate and F-777, making F-777 not a new song artist to have his song be in a main level.
The wave form was previously known as the 'dart'. RobTop changed the wave's name to 'dart' again in 2.0, but changed it back to 'wave' due to the complaints issued by the community.

Previews

3 August, 2014: Prior to the release of Update 1.8, Topala said in a conversation at Touch Arcade Forums, "I have a lot of ideas for Update 1.9 that could be huge for the game, but more on that after I release 1.8......... muahaha!"
13 August, 2014: Topala posts his first Update 1.9 preview image, which shows five icons wearing different-colored headphones. This makes way for much anticipation throughout the Geometry Dash community and results in theories involving soundtrack changes within a level and new game modes.
26 August, 2014: Topala publishes another image depicting 3-D blocks, arousing much excitement among Geometry Dash players.
28 August, 2014: Topala continues with the idea of 3-D blocks, posting a picture on Facebook about what could be built using them.
6 September, 2014: Another image is posted through Topala's social media accounts, featuring several different level components that could be used in future Geometry Dash levels. This includes two new icons, gear-like obstacles, and various different unknown types of blocks. The most prominent feature is a new thick blue portal that would likely result in the introduction of a new game mode.
14 September, 2014: Topala posts another image to social media, hinting the soundtracks for the upcoming levels. It has a blast and processor (which was later confirmed to be Blast Processing by Waterflame) and a book, an infinity symbol, and the number 2 (which in truth hinted to Theory of Everything 2 by both DJ Nate and F-777). The latter was correctly theorized to be a demon level, following similar lines to Update 1.6.
21 September, 2014: Another image is posted through Facebook and Twitter. It previews a new custom music feature that would allow players to include music from Newgrounds in their custom levels. The image includes ten icons with headphones at the bottom. It is the first picture to indicate that the update was a work in progress. Upon the release of the image, Topala says that a sneak peek video for the next levels would be coming soon.
28 September, 2014: Topala officially releases the first Update 1.9 sneak peek video, which shows the first 21 seconds of a beta version of Blast Processing. As seen in the video, the new blue portal changes the icon to an arrow-like object with physics similar to those seen in the mobile game, Wave Wave.
10 October, 2014: Topala releases another sneak peek video featuring the second level, Theory of Everything 2. In this video, a new background and a new design of ship is used. Topala is also playing the game on his PC, indicating that he may have been using the future Steam version.
18 October, 2014: Topala confirms that the update would be released soon after he had fixed a minor issues in the backup and music systems. He also says he is working on the Steam version, and hints on Update 2.0, stating that he will continue improving the user account system devised in 1.9.
4 November, 2014: Topala posts that the update is submitted for review and is waiting to be accepted.
9 November, 2014: Nearly three months after Update 1.9 was first mentioned, Topala confirms the release of 1.9 and states that it will be released on iOS and Android devices around the same time, and the Steam version would be released as soon as possible. It is eventually released on the Windows Phone, App Store, and several other mobile devices.
15 November, 2014: Update 1.9 is released on Amazon devices.
