[^footnote-1] Introduced in 2006, it served as a great free-software alternative -to proprietary products. Vyatta came in two editions: Vyatta Core -(formerly known as Vyatta Community Edition), which was free software, and -Vyatta Subscription Edition, which included proprietary features and was -available only to paying customers. - -Brocade Communications Systems acquired Vyatta in 2012. Shortly after, Brocade -renamed Vyatta Subscription Edition to Brocade vRouter, discontinued Vyatta -Core, and shut down the community forum without notice. The bug tracker and Git -repositories were closed the following year. - -By the time Brocade acquired Vyatta, the development of Vyatta Core had -already stagnated. The focus had shifted to Vyatta Subscription Edition, -where core components were replaced with proprietary software. As a result, -Vyatta Core received fewer new features, and some of those added faced issues. - -In 2013, shortly after Vyatta Core was discontinued, the community forked its -final version (6.6R1) to create the VyOS project. In 2014, the maintainers -established a company to fund VyOS development through technical support, -consulting services, and LTS release access subscriptions. The company was -originally named Sentrium and was later reorganized under the VyOS brand. - -## Major releases - -VyOS originally named its major versions after elements by atomic number. -Beginning with version 1.2, this naming scheme was changed. It now uses the -Latin names of constellations recognized by the International Astronomical -Union ([IAU](https://en.wikipedia.org/wiki/IAU_designated_constellations_by_area)), -ordered by their solid angle area, beginning with the smallest. - -### Hydrogen (1.0) - -Released just in time for the holidays on 22 December 2013, Hydrogen was -the first major VyOS release. It fixed features that were broken in -Vyatta Core 6.6, such as IPv4 BGP peer groups and DHCPv6 relay, and -introduced command scripting, a task scheduler, and web proxy LDAP -authentication. - -### Helium (1.1) - -Helium, released on 9 October 2014, marked the first anniversary of the -VyOS Project. The release introduced an event handler, L2TPv3 support, -802.1ad (QinQ), and IGMP proxy, as well as experimental support for VXLAN -and DMVPN. Notably, DMVPN remained non-functional in Vyatta Core due to its -reliance on a proprietary NHRP implementation. - -### Crux (1.2) - -Crux (the Southern Cross) was released on 28 January 2019 and marked a -departure from legacy Vyatta codebase and the start of the migration from -Perl to Python as the primary language. The underlying base system was -upgraded from Debian 6 (Squeeze) to Debian 8 (Jessie). - -Crux introduced many new features, some of the most noteworthy are: -an mDNS repeater, a broadcast relay, a high-performance PPPoE server, -an HFSC scheduler, and support for Wireguard, unicast VRRP, RPKI for BGP, -and fully 802.1ad-compliant QinQ ethertype. The telnet server and support -for P2P filtering were removed. - -Crux was the first VyOS release to feature a modular image build system. -CLI definitions were written using an XML syntax automatically checked -against a schema at build time. Python APIs were introduced for command -scripting and configuration migration. New Perl code and old-style (non-XML) -command definition were no longer accepted from that point. - -Crux reached the end of support in 2023. - -### Equuleus (1.3) - -Equuleus (the Little Horse) was a long-term support version released -on 21 December 2021, just in time for the winter holidays. - -Equuleus brought many long-awaited features, most notably an SSTP VPN -server, an IPoE server, an OpenConnect VPN server, and a serial console -server. It also introduced reworked support for WWAN interfaces, support -for GENEVE and MACSec interfaces, VRF, IS-IS routing, and preliminary support -for MPLS and LDP. - -Equuleus reached the end of support in 2025. - -### Sagitta (1.4) - -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). - -### Circinus (1.5) - -Circinus (the Drawing Compass) became generally available as an LTS release on -31 March 2026. Its development began in 2024 and focused on major performance -upgrades and modernizing core subsystems. - -Circinus introduces several major architectural improvements, most notably an -optional VPP-based accelerated dataplane. Using the DPDK driver, this dataplane -can offer performance up to 15x faster than the Linux kernel dataplane and -allows administrators to selectively enable hardware acceleration on a -per-interface and per-feature basis. - -Other significant additions and updates include: - -- A high-performance kernel-mode NetFlow sensor based on ipt-netflow, - replacing the older pmacct implementation. -- Unification of sFlow to exclusively use the much faster hsflowd - implementation. -- Transition of the DHCP server to a Kea-based implementation, replacing the - legacy, end-of-life ISC DHCPD. -- A completely rewritten WAN load balancing implementation to resolve - long-standing stability issues and introduce support for firewall groups in - load balancing rules. -- A new `execute` operational mode command family to separate action commands - that do not depend on or modify system configuration. - -The release also cleans up several legacy and underutilized components. -FastNetMon was removed, OpenVPN support for Blowfish and Twofish ciphers was -dropped for security reasons, and the Salt minion integration was deprecated. - -Like Sagitta (1.4), the underlying base system for Circinus remains Debian 12 -(Bookworm). - -### Scutum (1.6) - -Scutum (the Shield) is the codename for the upcoming development -branch. VyOS 1.6 Scutum has not been released yet. - -## A note on copyright - -Unlike Vyatta, VyOS has never had closed-source code and never will. -The only proprietary material in VyOS is non-code assets, such as -graphics and the trademark "VyOS".
