<h2>What happened?</h2> | <h2>Who needs to upgrade?</h2> | ||||
<p>The planned upgrade of the BCHA network has successfully been completed. The first post-upgrade block is block number <a href="https://explorer.bitcoinabc.org/block-height/686621">686621</a>.</p> | <p>All operators of a Bitcoin ABC full node must upgrade to the latest major version (0.24.x). This is available at our <a href="/releases"> Releases</a> page.</p> | ||||
<h2>I forgot to upgrade, what should I do?</h2> | <h2>Exactly when will the upgrade activate?</h2> | ||||
<p>If you forgot to upgrade, your node may have marked the upgraded chain as invalid. In order to fix this problem, simply upgrade to Bitcoin ABC version 0.23.4 or greater, available at our <a href="/releases">Releases page</a>.</p> | <p>In order to activate reliably at a predictable time, the network upgrade uses the "Median Time Past" mechanism. The upgrade activates when the median of the last 11 blocks reaches timestamp 1636977600 (12:00:00 UTC on November 15th, 2021). This means that the upgrade doesn't actually activate exactly at that time, but typically about one hour later, when 6 blocks with timestamps greater than the activation time have been produced.</p> | ||||

<p>The May 15th 2021 upgrade did not include any new protocol features. However, because of the automatic replay protection that is part of the 6-month upgrade cadence, it is necessary for all full node operators to upgrade to 0.23.x.</p> | <p>The November 15th 2021 upgrade does not include any new protocol features.
