-<h3 id="dependencies-upgrade">Dependencies Upgrade</h3>
-
-<p>Here is a list of dependencies changed in 4.7.2:</p>
-
-<ul>
- <li><a href="https://grpc.io/">Grpc</a> is upgraded from <code class="highlighter-rouge">1.5.0</code> to <code class="highlighter-rouge">1.12.0</code>. See <a href="https://github.com/apache/bookkeeper/pull/1441">apache/bookkeeper#1441</a></li>
- <li><a href="http://netty.io/">Netty</a> is upgraded from <code class="highlighter-rouge">4.1.12</code> to <code class="highlighter-rouge">4.1.22</code>. See <a href="https://github.com/apache/bookkeeper/pull/1441">apache/bookkeeper#1441</a></li>
- <li><a href="https://developers.google.com/protocol-buffers/">Protobuf</a> is upgraded from <code class="highlighter-rouge">3.4.0</code> to <code class="highlighter-rouge">3.5.1</code>. See <a href="https://github.com/apache/bookkeeper/pull/1466">apache/bookkeeper#1466</a></li>
- <li><a href="http://rocksdb.org/">RocksDB</a> is upgraded from <code class="highlighter-rouge">5.8.6</code> to <code class="highlighter-rouge">5.13.1</code>. See <a href="https://github.com/apache/bookkeeper/pull/1466">apache/bookkeeper#1466</a></li>
-</ul>
+<h3 id="dependency-changes">Dependency Changes</h3>
-<p><code class="highlighter-rouge">Reflective setAccessible(true)</code> is disabled by default in Netty while using java9+. This might result in performance degradation. Consider reenabling <code class="highlighter-rouge">Reflective setAccessible(true)</code> by setting
-environment value <code class="highlighter-rouge">io.netty.tryReflectionSetAccessible</code> to <code class="highlighter-rouge">true</code>. See <a href="https://github.com/netty/netty/pull/7650">netty/netty#7650</a> for more details.</p>
+<p>In 4.7.2, <a href="https://zookeeper.apache.org/">Zookeeper</a> version is downgraded from <code class="highlighter-rouge">3.5.3-beta</code> to <code class="highlighter-rouge">3.4.13</code> to avoid having a <code class="highlighter-rouge">beta</code> 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.</p>
