What is NATS?

NATS keeps two release lines in lockstep while slowly widening multi-tenant routing controls.

NATS maintains 2.14 and 2.15 in parallel, shipping matching patch and RC releases on both. The latest RCs add account-hash subject mapping functions and a new TLS verification option, while the October patches were mostly Go toolchain bumps carrying a certificate-trust CVE mitigation.

What is OpenWrt?

OpenWrt's releases are still set by security fixes, now mostly on the 25.12 branch.

OpenWrt 25.12 is the active stable series, and its sixth service release on October 19 fixed several remotely triggerable flaws in network services that are enabled by default. Nearly every release since March has been vulnerability response, from the Trail of Bits audit CVEs to odhcpd's DHCPv6 overflow and the dnsmasq backports. The 24.10 branch's last entry is 24.10.8 in July.

NATS vs OpenWrt: editorial side-by-side

N
NATS
DEVOPS
5.0

NATS keeps two release lines in lockstep while slowly widening multi-tenant routing controls.

◆ Current state

NATS maintains 2.14 and 2.15 in parallel, shipping matching patch and RC releases on both. The latest RCs add account-hash subject mapping functions and a new TLS verification option, while the October patches were mostly Go toolchain bumps carrying a certificate-trust CVE mitigation.

◆ Where it's heading

The project is in a stabilization phase: JetStream placement limits, gateway compatibility and security patches dominate. The new account-hash mapping functions are the only feature thread, aimed at operators running many isolated accounts and leafnodes.

◆ Prediction

Expect 2.15.3 and 2.14.10 to go final with the account-hash mapping functions, followed by more JetStream placement and limit fixes.

O
OpenWrt
DEVOPS
2.5

OpenWrt's releases are still set by security fixes, now mostly on the 25.12 branch.

◆ Current state

OpenWrt 25.12 is the active stable series, and its sixth service release on October 19 fixed several remotely triggerable flaws in network services that are enabled by default. Nearly every release since March has been vulnerability response, from the Trail of Bits audit CVEs to odhcpd's DHCPv6 overflow and the dnsmasq backports. The 24.10 branch's last entry is 24.10.8 in July.

◆ Where it's heading

Releases are driven by disclosures in default services such as odhcpd and dnsmasq, with device support added on the side. 24.10 appears to be winding down, which leaves 25.12 as the only line getting fixes.

◆ Prediction

Expect a 25.12.7 when the next default-service CVE batch lands; whether 24.10 gets any further release is unclear from the feed.
