    <description descriptionType="Abstract">&lt;p&gt;Adds a number of important &lt;strong&gt;updates and bug fixes&lt;/strong&gt;, including:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;fixes Windows-specific problems related to 32- vs 64-bit integers.&lt;/li&gt;
	&lt;li&gt;adds tools to estimating the wall time needed to execute an experiment design on a quantum processor.&lt;/li&gt;
	&lt;li&gt;fixes issues with &lt;code&gt;extras.interpygate&lt;/code&gt; so that germ selection works and the number of gauge parameters can be specified manually.&lt;/li&gt;
	&lt;li&gt;adds &lt;code&gt;&amp;quot;pad_1Q&amp;quot;&lt;/code&gt; implicit idle mode, which pads empty space in a circuit with 1-qubit idle operations.&lt;/li&gt;
	&lt;li&gt;adds SPAM and instrument elements to processor specifications.&lt;/li&gt;
	&lt;li&gt;adds &lt;code&gt;QuditProcessorSpec&lt;/code&gt; object, so that processors containing multiple &lt;em&gt;qudits&lt;/em&gt; can be readily modeled.&lt;/li&gt;
	&lt;li&gt;fixes bugs and adds functionality to first-order-gauge-invariant (FOGI) analysis routines.&lt;/li&gt;
	&lt;li&gt;improves circuit simulation performance when using operation factories (e.g., for modeling continuously parameterized gates)&lt;/li&gt;
	&lt;li&gt;revamps elementary error generator functionality to closely match arXiv:2103.01928, where there are H, S, C, and A type elementary generators.&lt;/li&gt;
	&lt;li&gt;default gauge optimization workflow changed for Lindblad-constrained models: now these models are converted to TP and gauge optimized over the entire TP gauge group (unitary group optimization was seen to be problematic for Lindblad-constrained models).&lt;/li&gt;
	&lt;li&gt;fixes a bug in Hessian projection that affects (and corrects) error bar computation.&lt;/li&gt;
&lt;/ul&gt;</description>
