+### Dependency Changes
-### Dependencies Upgrade
-
-Here is a list of dependencies changed in 4.7.2:
-
-- [Grpc](https://grpc.io/) is upgraded from `1.5.0` to `1.12.0`. See
[apache/bookkeeper#1441](https://github.com/apache/bookkeeper/pull/1441)
-- [Netty](http://netty.io/) is upgraded from `4.1.12` to `4.1.22`. See
[apache/bookkeeper#1441](https://github.com/apache/bookkeeper/pull/1441)
-- [Protobuf](https://developers.google.com/protocol-buffers/) is upgraded from
`3.4.0` to `3.5.1`. See
[apache/bookkeeper#1466](https://github.com/apache/bookkeeper/pull/1466)
-- [RocksDB](http://rocksdb.org/) is upgraded from `5.8.6` to `5.13.1`. See
[apache/bookkeeper#1466](https://github.com/apache/bookkeeper/pull/1466)
-
-`Reflective setAccessible(true)` is disabled by default in Netty while using
java9+. This might result in performance degradation. Consider reenabling
`Reflective setAccessible(true)` by setting
-environment value `io.netty.tryReflectionSetAccessible` to `true`. See
[netty/netty#7650](https://github.com/netty/netty/pull/7650) for more details.
+In 4.7.2, [Zookeeper](https://zookeeper.apache.org/) version is downgraded
from `3.5.3-beta` to `3.4.13` to avoid having a `beta` dependency and address
maturity concerns.
+The downgrade is safe and smooth. No extra actions are required from switching
bookkeeper 4.7.1 to 4.7.2.
