The start

Onyx began development in November 2017, with the codename "Vertigo", and based on Iris OS '16. In 2018, a milestone 1 developer preview was released in July of that year. In the developer preview, the UI was called "NDE", an alpha version of Aurora UI. The version number calls itself "ecSoft Codename Vertigo Dev Preview". This build includes the new Start screen and lots of placeholders in the aforementioned feature, including the Search menu, which was removed in the final build.

Announcement and milestone 2 beta

In August 2018, a milestone 2 beta version was compiled, with the UI now calling itself just "Aurora" instead of Aurora UI. It was announced in August 2018 as "Onyx". Milestone 2 includes a beta version of the new Notes app, widgets, and a redesigned display properties panel. Another beta in the Milestone 2 was compiled on September 2018, and includes major changes to the Start screen to look similar to the RTM.


On launch, the OS received negative reviews regarding the amount of bugs the OS had on day one. iriSoft addressed an lot of the bugs users complained about, now making the OS having generally positive reviews.
