Development
Onyx began development in 2018, with the codename "Vertigo", and based on Iris OS '18. The same year, 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". In August 2018, a milestone 2 pre-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.
