## Cadence Server & CLI v0.18.0
### Notes
- **Allow using Kafka TLS without cert ca and key (#3862)**
`EnableHostVerification` started to be used for Kafka TLS, by default it’s false and which means `InSecureSkipVerify` is true for Kafka TLS. But previously `InSecureSkipVerify` is false. If you want to keep the same behavior, please update your config to set `EnableHostVerification` to be true. It won’t break anything if not doing so, but may be risky to not verify it. This option is basically the inverse of InSecureSkipVerify. See http://golang.org/pkg/crypto/tls/ for more info.

- **Support visibility query with close status represented in string (#3865)**
Advanced workflow visibility record query syntax now supports using string as workflow close status. Accepted values are: `COMPLETED`, `FAILED`, `CANCELED`, `TERMINATED`, `CONTINUED_AS_NEW` and `TIMED_OUT`, case insensitive.

### New Features & Improvements
- GRPC
- Task Processing
- Replication
- Scanner
- Workflow Reset
- ElasticSearch
- Kafka
- SQL
- Others
- Misc.

## Cadence Server & CLI v0.17.0
### Release note: Upgrade Cadence server to the latest 0.16.x release prior to deploying this release.

0.17 has a change that is not compatible with releases before 0.15.

Please consider upgrade the Cadence server to the latest 0.16.x release before deploying this release.

        decodingTypes: [ "thriftrw" ]
````
to persistence configuration like in this [example](https://github.com/uber/cadence/commit/b2464b709fc91c453b2e21c7092e658f6112b76f#diff-019c991260a37dc5f2cc86170b07b43284cc2f66ea636cfeb00cd0a92f9639d1R17)
