For a long time there is a dev build for FP4 and Android T (13)

Until now there is no stable yet

Do you have information when it will be available?
I’m using 1.17-t-stable-FP4 (it was available for a short time). Will I be able to use the Updater?
In about a month, it should be available:
A so-called “stable” aka “official” version is only available for very few devices of the total officially supported by /e/OS : 250
- Are built based on source code from the Community build branch which has been released and tested
- This build undergoes additional and longer testing cycles
- Builds are made by /e/OS using the /e/OS build infrastructure and signed by /e/OS stable keys
A so-called “stable” aka “official” is nothing more than “tested” d/e/v builds. I would not overestimate the quality of the build, because the “community” builds usually run just as well.
