     1  # Version
     2  
     3  The Simple IoT app stores and uses three different version values:
     4  
     5  - App Version
     6  - OS Version
     7  - HW Version
     8  
     9  The App version is compiled into the application Go binary by the build (see the
    10  [`envsetup.sh`](https://github.com/simpleiot/simpleiot/blob/master/envsetup.sh)
    11  file). This version is based on the latest Git tag plus hash if there have been
    12  any changes since the tag.
    13  
    14  On Linux, the OS version is extracted from the `VERSION` field in
    15  `/etc/os-release`. The field can be [changed](../user/configuration.html) using
    16  the `OS_VERSION_FIELD` environment variable.
    17  
    18  The versions are displayed in the root node as shown below:
