Packages are imported one by one in alphabetical order during runtime.

The test doesn't identify package's order-dependent issues; for instance,
importing "tf.foo" followed by "tf.bar" won't reveal that "tf.bar" depends on
"tf.foo" being imported first.

The `_api/v2/api_packages.txt` file is generated during the TensorFlow API v2
init files creation process and is subsequently stored in the wheel file after

# Release 1.15.0

This is the last 1.x release for TensorFlow. We do not expect to update the 1.x
branch with features, although we will issue patch releases to fix
vulnerabilities for at least one year.
