## 18.09.8
2019-07-17
### Runtime
* Masked the secrets updated to the log files when running Docker Engine in debug mode. [CVE-2019-13509](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-13509): If a Docker engine is running in debug mode, and `docker stack deploy` is used to redeploy a stack which includes non-external secrets, the logs will contain the secret.
### Client
* Fixed rollback config type interpolation for `parallelism` and `max_failure_ratio` fields.
### Known Issue
* There are important changes to the upgrade process that, if not correctly followed, can have an impact on the availability of applications running on the Swarm during upgrades. These constraints impact any upgrades coming from any version before 18.09 to version 18.09 or later.
