Introducing XRP Ledger (rippled) version 1.2.4
Ripple has released version 1.2.4 of rippled, the reference implementation of the core XRP Ledger protocol.
Version 1.2.4 improves the verification and routing of shard crawl requests and imposes a 20 second timeout onto the component that checks for an updated validator list to prevent it from becoming blocked for an indefinite amount of time.
Action Required
If you operate an XRP Ledger server, then you should upgrade to version 1.2.4 immediately.
Impact of Not Upgrading
If you operate a rippled server, but do not upgrade to 1.2.4 immediately, then your server may experience restarts or outages and may be unable to retrieve updated validator lists from the publishers that you have configured.
Additionally, if you are not already running release 1.2.0 or greater, then your server is amendment blocked, meaning that it:
Cannot determine the validity of a ledger;
Cannot submit or process transactions;
Cannot participate in the consensus process;
Cannot vote on future amendments; and
Could rely on potentially invalid data.
