OpenWrt vs Slurm
A side-by-side editorial comparison of OpenWrt and Slurm — release velocity, themes, recent moves, and the top alternatives to consider.
OpenWrt vs Slurm: at a glance
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.
What is Slurm?
Slurm's 26.05 line settles into routine fixes after September's seven-CVE release.
Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes: qstat -f output, a slurmd double free and powered-down nodes placed incorrectly. 26.05.3 in August added external nodes in heterogeneous jobs.

OpenWrt
2.5DEVOPS
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.
Slurm
2.5DEVOPS
Slurm's 26.05 line settles into routine fixes after September's seven-CVE release.
◆ Current state
Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes: qstat -f output, a slurmd double free and powered-down nodes placed incorrectly. 26.05.3 in August added external nodes in heterogeneous jobs.
◆ Where it's heading
The 26.05 line, which introduced SLUID identity and an in-tree TLS path in May, is past its security scramble and into routine point releases. Older branches get backports only when a security fix requires it.
◆ Prediction
Expect 26.05.6 on a similar monthly pace with reliability fixes; another coordinated security release would again cover all three branches.
