-
-VyOS is an open-source network operating system that provides a single unified 
-CLI and API to manage routing protocols, firewall and NAT, QoS, load balancing, 
-DHCP and DNS servers, and many other features.
-
-VyOS runs on a wide variety of commodity hardware, virtual machines, and 
-multiple cloud environments.
-
-We provide a dedicated user guide for each major 
-VyOS release that receives long-term support (LTS). We maintain multiple user 
-guide versions, all hosted at https://docs.vyos.io. 
-To switch between versions, select the appropriate version in the bottom-right 
-corner.
-
-VyOS CLI syntax may vary between major and sometimes minor releases. Always 
-refer to the documentation matching your current running installation. If 
-a change in the CLI is required, VyOS provides a migration script to handle 
-the syntax adjustments. No user action is required.

-History
-#######
-
-In the beginning...
-===================
-
-There was a network operating system based on Debian GNU/Linux, called 
-Vyatta. [*]_ 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.
