<div class="post-content" itemprop="articleBody">
<p>After a longer time of “bugfix releases” only, the Eclipse Ditto team is once again happy to announce the availability
of a new minor release, including new features: Ditto <a href="https://projects.eclipse.org/projects/iot.ditto/releases/3.6.0">3.6.0</a>.</p>
<p>The most work in this release went into the enforcement/validation of a linked WoT (Web of Thing) “Thing Model” to make
sure that a Ditto managed digital twin can only be modified in ways which are valid based on the defined WoT model.</p>
<p>But also other features like SSO in the Ditto-UI were added, so inform yourself in this blogpost about the changes in
the new release.</p>
<h2 id="adoption">Adoption</h2>
<p>Companies are willing to show their adoption of Eclipse Ditto publicly:
<a href="https://iot.eclipse.org/adopters/?#iot.ditto">https://iot.eclipse.org/adopters/?#iot.ditto</a></p>
<p>When you use Eclipse Ditto it would be great to support the project by putting your logo there.</p>
<h2 id="changelog">Changelog</h2>
<p>The main improvements and additions of Ditto 3.6.0 are:</p>
<ul>
<li><strong>WoT (Web of Things)</strong> Thing Model based validation of modifications to things and action/event payloads</li>
<li><strong>AWS IAM based authentication</strong> against <strong>MongoDB</strong></li>
<li>Configure <strong>defined aggregation queries</strong> to be <strong>exposed as Prometheus metrics</strong> by Ditto periodically</li>
<li><strong>SSO (Single-Sign-On)</strong> support in the Ditto UI via OpenID connect provider configuration</li>
</ul>
<p>The following non-functional work is also included:</p>
<ul>
<li>Update Java runtime to <strong>run Eclipse Ditto with</strong> to <strong>Java 21</strong></li>
<li>Run <strong>Ditto system tests</strong> in <strong>GitHub actions</strong></li>
</ul>
<p>The following notable fixes are included:</p>
<ul>
<li>Fix <strong>JWT placeholder</strong> not resolving correctly in <strong>JSON arrays nested</strong> in JSON objects</li>
<li>Fix <strong>retrieving a Thing</strong> at a <strong>given historical timestamp</strong></li>
<li>Generating UNIX “Epoch” as neutral element when creating new things based on WoT TM models for types declared as “date-time” format</li>
</ul>
