The nightly builds and CyanogenMod for the future's smartphones will no longer be available as the company plans to stop operating by year's end.

Cyanogen shutdown was initially announced through an official blog post on Dec. 23. It reads "All services and Cyanogen-supported nightly builds will be discontinued no later than 12/31/16."

While the service is shutting down, the open source project and source code will still remain usable for developers who want to build CyanogenMod in person.

Cyanogen has laid off 30 of the company's staffs, following Steve Kondik resignation. The master of Cyanogen blames CEO Kirt McMaster for the company's failure, as told by Android Police. As for now, the future is uncertain for CyanogenMod and the devices that use the OS.

Which devices get affected by Cyanogen shutdown?

Devices running Cyanogen OS such as Lenovo ZUK Z1 and OnePlus One will no longer get any OS update from Cyanogen as the shutdown means no more development on the firmware. However, the open source ROM will still remain available for community developers.

Thanks for all the support during this rough ride. Time for the next adventure :)

Many have doubted whether the open source code could mean a positive future for CyanogenMod as a few tech analysts described the shutdown as a 'death blow' to the modified ROM as many of the executives chose to depart.

Cyanogen Inc. has popularized CyanogenMod - the most-used custom ROM - for three years and aimed to take on Google's Android by claiming its build as a 'better version of Android' due to the OS mods. The brand's death declaration is reportedly a birth of a new mod called Lineage, according to Cnet.

Your Lineage will finish what you started, Cid

The new custom ROM, Lineage OS is developed by the community and it will continue the work of CyanogenMod after it is shutdown.
