Notable Changes

Various security, performance, accuracy, and stability issues have been fixed.

JA4

JA4 for TLS and QUIC has been backported to Suricata 7.0.6.

It is disabled by default. If rules use JA4, it will be partially enabled. Alerts will be generated and contain the JA4 in the alert record. TLS records in EVE will only add JA4 when explicitly enabled in the configuration.

EOL for Suricata 6

The Suricata 6.0.x branch will go End of Life (EOL) in July 2024. This means no more support, updates and fixes for the 6.0.x branch. 6.0.20 is likely the last release in the 6-series.

All users of Suricata 6 or earlier are strongly recommended to update to Suricata 7 as soon as possible.
