-## Duplicate ARM Assets
-
-Each Electron release includes two identical ARM builds with slightly different 
-filenames, like `electron-v1.7.3-linux-arm.zip` and 
-`electron-v1.7.3-linux-armv7l.zip`. The asset with the `v7l` prefix was added 
-to clarify to users which ARM version it supports, and to disambiguate it from 
-future armv6l and arm64 assets that may be produced.
-
-The file _without the prefix_ is still being published to avoid breaking any 
-setups that may be consuming it. Starting at 2.0, the un-prefixed file will 
-no longer be published.
-
-For details, see
-[6986](https://github.com/electron/electron/pull/6986)
-and 
-[7189](https://github.com/electron/electron/pull/7189).
