# Updating Airflow
|
|
|
|
This file documents any backwards-incompatible changes in Airflow and
|
|
assists people when migrating to a new version.
|
|
|
|
|
|
## Airflow 1.8
|
|
|
|
### Changes to Behavior
|
|
|
|
#### New DAGs are paused by default
|
|
|
|
Previously, new DAGs would be scheduled immediately. To retain the old behavior, add this to airflow.cfg:
|
|
|
|
```
|
|
[core]
|
|
dags_are_paused_at_creation = False
|
|
```
|
|
|
|
### Deprecated Features
|
|
These features are marked for deprecation. They may still work (and raise a `DeprecationWarning`), but are no longer supported and will be removed entirely in Airflow 2.0
|
|
|
|
- Hooks and operators must be imported from their respective submodules
|
|
|
|
`airflow.operators.PigOperator` is no longer supported; `from airflow.operators.pig_operator import PigOperator` is. (AIRFLOW-31, AIRFLOW-200)
|
|
|
|
- Operators no longer accept arbitrary arguments
|
|
|
|
Previously, `Operator.__init__()` accepted any arguments (either positional `*args` or keyword `**kwargs`) without complaint. Now, invalid arguments will be rejected. (https://github.com/apache/incubator-airflow/pull/1285)
|
|
|
|
## Airflow 1.7.1.2
|
|
|
|
### Changes to Configuration
|
|
|
|
#### Email configuration change
|
|
|
|
To continue using the default smtp email backend, change the email_backend line in your config file from:
|
|
|
|
```
|
|
[email]
|
|
email_backend = airflow.utils.send_email_smtp
|
|
```
|
|
to:
|
|
```
|
|
[email]
|
|
email_backend = airflow.utils.email.send_email_smtp
|
|
```
|
|
|
|
#### S3 configuration change
|
|
|
|
To continue using S3 logging, update your config file so:
|
|
|
|
```
|
|
s3_log_folder = s3://my-airflow-log-bucket/logs
|
|
```
|
|
becomes:
|
|
```
|
|
remote_base_log_folder = s3://my-airflow-log-bucket/logs
|
|
remote_log_conn_id = <your desired s3 connection>
|
|
```
