|
|
* The latest release of a major version will remain compatible with
|
|
* the backend services for at least one year from the date when the
|
|
* following major version is released. [...]
|
|
* Half way through to that period (6 months), old major versions of the
|
|
* balena CLI will start printing a deprecation warning message.
|
|
* At the end of that period, older major versions will abort with an error
|
|
* message unless the `--unsupported` flag is used.
|

*
|
|
* - Check for new balena-cli releases by querying the npm registry.
|
|
* - Cache results for a number of days to improve performance.
