Sagitta (1.4)
-------------
-Sagitta (the Arrow), released in 2024, is currently a supported LTS release.
+Sagitta (the Arrow), the current LTS release, became generally available on
+4 June 2024. Its development began in late 2021 and focused on eliminating
+remaining legacy components and reworking core subsystems.
+
+The transition to XML-defined command definitions and script refactoring with
+separate verify, update, and apply stages were completed. The firewall
+subsystem was rebuilt on nftables, introducing interface-independent rulesets
+and the reimplemented zone-based firewall model. The PKI subsystem was
+redesigned to manage cryptographic material directly within the configuration
+file.
+
+Sagitta introduced rollback without reboot, support for Babel and PIM6 routing
+protocols, failover routes, segment routing, NAT64, an IKEv2 remote-access VPN
+server, Zabbix monitoring, HTTP load balancing, and configuration
+synchronization using the HTTP API.
+
+The underlying base system was upgraded to Debian 12 (Bookworm).
