 <h2>Zcash Beta Series</h2>
 <p>The Beta series is the final phase of development prior to the launch of Zcash 1.0.0, which begins the <a class="reference external" href="/sprout-roadmap/">Sprout Series</a>. The Beta Series is notably different from our earlier alpha releases in several ways:</p>
 <ul class="simple"><li>We're using a new versioning scheme, the first beta release is <cite>v1.0.0-beta1</cite>, the next <cite>v1.0.0-beta2</cite> and so on.</li>
-<li>Starting with <cite>v1.0.0-beta1</cite> the new high level <a class="reference external" href="https://github.com/zcash/zcash/blob/v1.0.0-beta1/doc/payment-api.md">RPC interface</a> is in place. The early RPC interface is deprecated and will be removed.</li>
+<li>Starting with <cite>v1.0.0-beta1</cite> the new high level <a class="reference external" href="https://zcash.readthedocs.io/en/latest/rtd_pages/rtd_docs/payment_api.html">RPC interface</a> is in place. The early RPC interface is deprecated and will be removed.</li>
 <li>Only high priority changes will be merged, including: important security mitigations, fixing bugs which inhibit basic operation, improving build, packaging, and documentation, and changes for production infrastructure.</li>
 </ul><p>As we approach our target 1.0 Sprout launch date of October 28th, 2016, we'll release several Beta versions. During this time we'll be working with partners and community members to integrate Zcash into more tools, products, and services.</p>
 <p><em>The Zcash Beta Series is a good time for integration work for third party services and products interested in deploying Zcash support.</em></p>
