ChristopherMayes/Xopt: Xopt v2.0.0
<p>We are pleased the second major release of Xopt, with major changes of all high-level objects embrace the latest <a href="https://docs.pydantic.dev/latest/">Pydantic</a> V2. Some highlights are:</p>
<ul>
<li>Objects <code>Xopt</code>, <code>VOCS</code>, <code>Evaluator</code>, and all Generators inherit from <a href="https://docs.pydantic.dev/latest/api/base_model/#pydantic.BaseModel"><code>pydantic.BaseModel</code></a></li>
<li>Xopt VOCS objects now contain "observables" attribute to store observed data that is not directly maximized or minimized for more complex algorithms (BAX)</li>
<li>Asynchronous behavior is now implemented in a separate <code>AsynchronousXopt</code> object, which allows for the base <code>Xopt</code> object to be simpler.</li>
<li>Multiple bugs with BO have been fixed, especially with constraints and trust region BO</li>
<li>Enables new features including Heteroskedastic noise models, fixed feature GP models, and evaluate functions returning multiple observations for a single input dict</li>
</ul>
<p>Special thanks to @nikitakuklev for the careful migration from Pydantic v1 to v2.</p>
<h2>Migration from V1</h2>
<p>Users of previous versions will need to modify their YAML inputs. In particular, the <code>xopt:</code> field is no longer needed in the YAML, because its options are now at the top level. So,</p>
<pre><code class="language-yaml">xopt:
max_evalulations: 100
vocs:
...
</code></pre>
<p>Is now:</p>
<pre><code class="language-yaml">max_evalulations: 100
vocs:
...
</code></pre>
<p>Pydantic will raise errors if fields are missing or if additional fields are not allowed.</p>
