+
+<p>Apache Calcite Avatica Go 4.0.0 is a major release with numerous improvements and a breaking change for Apache Phoenix.
+As this a a new major version, users of this package will need to upgrade their import paths to 
+<code class="highlighter-rouge">"github.com/apache/calcite-avatica-go/v4"</code>.</p>
+
+<p><strong>Breaking change for Apache Phoenix (<a href="https://issues.apache.org/jira/browse/CALCITE-2724">CALCITE-2763</a>):</strong> 
+In Apache Phoenix, null and empty strings are equivalent. For some background on why this is the case, see
+<a href="https://issues.apache.org/jira/browse/PHOENIX-947">PHOENIX-947</a>. In version 3 of Avatica-Go and below, null and empty
+strings are returned as an empty string <code class="highlighter-rouge">""</code> to the client. This prevented database/sql’s built in NullString type from
+working correctly. From 4.0.0 onwards, null and empty strings will be returned as a <code class="highlighter-rouge">nil</code>. This allows the usage of the
+<code class="highlighter-rouge">sql.NullString</code> type.</p>
+
+<p>For this release, both <a href="https://github.com/golang/dep">dep</a> and Go modules are supported for package management. As 
+Go modules will be turned on by default in Go 1.13.0 (estimated to be released in September/October 2019), it is highly
+recommended that users of this package start migrating to using Go modules to ease the transition.</p>
+

+<p>Apache Calcite Avatica Go 4.0.0 is a major release with numerous improvements and a breaking change for Apache Phoenix.
+As this a a new major version, users of this package will need to upgrade their import paths to 
+<code class="highlighter-rouge">"github.com/apache/calcite-avatica-go/v4"</code>.</p>
+
+<p><strong>Breaking change for Apache Phoenix (<a href="https://issues.apache.org/jira/browse/CALCITE-2724">CALCITE-2763</a>):</strong> 
+In Apache Phoenix, null and empty strings are equivalent. For some background on why this is the case, see
+<a href="https://issues.apache.org/jira/browse/PHOENIX-947">PHOENIX-947</a>. In version 3 of Avatica-Go and below, null and empty
+strings are returned as an empty string <code class="highlighter-rouge">""</code> to the client. This prevented database/sql’s built in NullString type from
+working correctly. From 4.0.0 onwards, null and empty strings will be returned as a <code class="highlighter-rouge">nil</code>. This allows the usage of the
+<code class="highlighter-rouge">sql.NullString</code> type.</p>
+
+<p>For this release, both <a href="https://github.com/golang/dep">dep</a> and Go modules are supported for package management. As 
+Go modules will be turned on by default in Go 1.13.0 (estimated to be released in September/October 2019), it is highly
+recommended that users of this package start migrating to using Go modules to ease the transition.</p>
