daniil@sentrium.io (Daniil Baturin) — Tue, 31 Mar 2026 00:30:00 GMT

Hello, Community!

VyOS 1.5.0 LTS release is now finalized and its CLI is frozen for any non-compatible changes. Right now subscribers can already download the generic ISO and other on-premises flavors for x86-64 systems. If you are contributing to VyOS and want LTS release images for personal use, remember that we are happy to share them through contributor subscriptions.

Its development started in 2024 and followed the usual two-year LTS release cycle. In those two years we introduced multiple big features including a long-awaited accelerated dataplane and a huge amount of bug fixes.

VyOS Project September 2025 Update

daniil@sentrium.io (Daniil Baturin) — Wed, 15 Oct 2025 15:15:52 GMT

Hello, Community! The holiday season in the Northern hemisphere is over and it's very visible in the commit log. There are lots of things that happened in VyOS in September — that includes a new, more performant kernel mode NetFlow sensor; the equally long-awaited support for using firewall groups in WAN load balancing rules; improvements that will hopefully make config corruption on power loss very unlikely; TLS support for syslog; and many more smaller features and fixes.

VyOS Project August 2025 Update

daniil@sentrium.io (Daniil Baturin) — Tue, 02 Sep 2025 10:15:05 GMT

Hello, Community!

We have some big news for you all in August — the count of changes that VyOS maintainers and community member made this month is small, but their impact makes up for the low number. They include VRF support for DHCP and DHCPv6 servers, steady progress in the legacy configuration backend replacement, multiple bug fixes, and an experimental privilege separation feature that allows limiting users to specific sets of operational commands.

VyOS Project July 2025 Update

daniil@sentrium.io (Daniil Baturin) — Wed, 06 Aug 2025 12:00:00 GMT

Hello, Community!

This month's update looks small — just a few small features and a bunch of bug fixes. One reason is the vacation season, of course. Some people (namely, I and Yuriy) went to DebConf 2025 rather than a vacation, where we heard a lot of interesting talks and had productive conversations with Debian developers — the biggest thing is that we will likely be able to contribute our improvements to live-build back to upstream which is great

The other reason is that there are lots of big developments in-progress that do not have visible effects yet, including an operational mode rework that will open up a pathway to operator-level user access controls; the ongoing work on rewriting the configuration backend; VPP support for VRRP, sFlow support for VPP, and BRAS protocols.

Hello, Community!

VyOS Stream 1.5-2025-Q2 and its corresponding source tarball are now available for download. This is the second VyOS Stream release on the way to the upcoming VyOS 1.5 LTS, and it includes multiple bug fixes and improvements, including the new implementation of WAN load balancing, a general mechanism for allowing conntrack-unfriendly protocols in transparent bridge firewalls, a fix for CVE-2025-30095 (active MitM in console server SSH connections) that was already delivered in VyOS 1.4.2, and more.

VyOS Project Update February 2025

daniil@sentrium.io (Daniil Baturin) — Thu, 27 Feb 2025 00:00:00 GMT

Hello, Community! February was a busy month for us: we merged the initial implementation of an accelerated dataplane into the rolling release branch, added a rewritten implementation of WAN load balancing, revamped the syslog configuration, and fixed a whole bunch of bugs. Read on for details!

VyOS Project November 2024 Update

daniil@sentrium.io (Daniil Baturin) — Fri, 29 Nov 2024 14:06:15 GMT

Hello, Community!

The November update is here. This post is short, but not all we've done lately: many internal changes in the configuration system will soon significantly improve commit speeds and open up a path to even more significant improvements. The 1.4.1 release is around the corner, together with the first VyOS Stream image — all built by the new CI system that produces tarballs with the corresponding source code for every image. But now, let's focus on the changes we made in the rolling release in October.
