|
|||

</ol><p>Note that this release does not reset the beta testnet and continues to uses the beta 2 proving and verify keys. <strong>NOTE:</strong> <cite>It does however make a change to the local block index format that will cause all upgraded nodes to fail to start (because they can’t parse the old block index format). As the error message will say, please start up your node once with the reindex flag after upgrading (ie.</cite> <tt class="docutils literal">./src/zcashd <span class="pre">-reindex</span></tt> <cite>) to resolve this issue.</cite></p>
