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