If you run the new v1.3.2.1 and you are on the wrong chain, it will close. In that case, follow the instructions on the bottom of the page for getting and installing a SnapShot:
https://www.beancash.org/downloads.html1.3.1 (or any older version before it) should not be used anymore (especially to sync the chain). Since we didn't have a majority upgrade to v1.3.1 in time (over 2 months notice was given), we stayed with the majority and followed the longer chain (up until August 2nd.) v1.3.1 started enforcing the new timedrift rules on July 13th., but there was no blocks violating the new rules until shortly after July 19th., when a block was created more than 10 minutes too early. Since at that time we still didn't have a majority of nodes upgraded, we had everyone stay on the long chain. By the beginning of August we had a majority of nodes that had updated to v1.3.1 and v1.3.2 (which started enforcement of the new time drift rules on August 2), since that time the majority of the network was now enforcing the new time drift rules and the majority of nodes stayed on the chain following the new rules. v1.3.2 not only started enforcement of the new rules, but also no longer synchronizes with old nodes (those running before v1.3.0.0). v1.3.2.1 reverts a change that was impacting network performance and introduces a new Proto version, which will lock in the protocol changes when the majority is running v1.3.2.1. Once we reach a majority running v1.3.2.1, v1.3.3 will be released, which will once deployed, eliminate the orphans being generated by the old nodes and complete the network upgrade
