Reminder: Upgrade your Bro installation! Stability updates in 2.4.1
Bro 2.5 is not far away, but in the meantime you should upgrade to Bro 2.4.1. This is the latest stable release. If you are running 2.4 the upgrade to 2.4.1 won't break your config. This release contains important fixes without changing Bro's functionality.
Not sure which one your version is? 'bro --version' will tell you.
