What 'discontinued' means

### What  does a 'discontinued' or 'Legacy' device mean

  -  newly released applications like App Lounge and Advanced privacy are not customized for these OS versions.

  -  lack of dedicated ROM Maintainers

  -  no support upstream (Lineage dropped support for Pie sometime back)

  -  no support upstream on Lineage

  -  device trees will continue to exist in the [Gitlab](https://gitlab.e.foundation/e) 

  -  users with build skills can create custom ROMs on these versions

  -  users with build skills can [create unofficial or custom ROMs]({% translate_link build-status %}) on these versions

  -  Security patches and vendor patches for the Pie, Oreo and Nougat code will be updated based on availability.

  - Google stops security patches for OS after some time. Similarly, Vendors drop support for older models when they release newer models in the market. Then it depends on developers from various communities to [backport](https://github.com/LineageOS/android_build/commit/4e4d9b094bc8df3bd06c74a993261058745c7733) the patches.

  - OS versions which will not receive support are marked as 'Legacy' in our [Supported Devices list](https://doc.e.foundation/devices). 

  - Devices marked as 'Legacy' will no longer receive any updates from the /e/OS team.
