SimpleSAMLphp vs OpenWrt: at a glance
What is SimpleSAMLphp?
Two maintained branches, and most of the shipping cadence is CVE response.
SimpleSAMLphp is running 2.4.x and 2.5.x in parallel, patching both from the same fix sets. Of the eight most recent releases, four are security releases and the rest are unlabelled bugfix drops. Release notes carry no feature detail at all — each is a short boilerplate paragraph plus SHA-256 checksums for the slim and full tarballs, with the actual content deferred to a separate changelog and upgrade notes.
What is OpenWrt?
Two stable branches, and the release cadence is now set by CVE disclosure.
OpenWrt is maintaining 24.10 in security-only mode with end of life projected for September 2026, while 25.12 — released in March 2026 after more than a year and over 4,700 commits — carries active development. Nearly every release in the last five months is driven by vulnerability response: a Trail of Bits audit of OpenWrt's own components in February produced four CVEs in umdns, jsonpath and procd, and the odhcpd DHCPv6 server has since yielded a critical stack overflow plus use-after-free and memory disclosure bugs. The 25.12 release itself replaced opkg with apk and was named for Dave Täht.

SimpleSAMLphp
0.0DEVOPS
Two maintained branches, and most of the shipping cadence is CVE response.
◆ Current state
SimpleSAMLphp is running 2.4.x and 2.5.x in parallel, patching both from the same fix sets. Of the eight most recent releases, four are security releases and the rest are unlabelled bugfix drops. Release notes carry no feature detail at all — each is a short boilerplate paragraph plus SHA-256 checksums for the slim and full tarballs, with the actual content deferred to a separate changelog and upgrade notes.
◆ Where it's heading
This is maintenance-mode infrastructure, and the release rhythm is set by vulnerability disclosure rather than a roadmap. The dual-branch discipline — shipping 2.4.6 and 2.5.1 within a minute of each other for the same three advisories — indicates a deployed base that cannot all move to the newer minor. The vulnerability classes are notable in themselves: HTTP-Artifact resolution and SP-Proxy deployments bridging identity providers of different trust levels.
◆ Prediction
Expect the 2.4 and 2.5 branches to keep receiving paired patches, with 2.4 continuing until an announced end-of-life. The entries give no indication of what is planned beyond the 2.5 line.
OpenWrt
2.5DEVOPS
Two stable branches, and the release cadence is now set by CVE disclosure.
◆ Current state
OpenWrt is maintaining 24.10 in security-only mode with end of life projected for September 2026, while 25.12 — released in March 2026 after more than a year and over 4,700 commits — carries active development. Nearly every release in the last five months is driven by vulnerability response: a Trail of Bits audit of OpenWrt's own components in February produced four CVEs in umdns, jsonpath and procd, and the odhcpd DHCPv6 server has since yielded a critical stack overflow plus use-after-free and memory disclosure bugs. The 25.12 release itself replaced opkg with apk and was named for Dave Täht.
◆ Where it's heading
The project is being audited seriously for the first time in a while, and it shows — the security sections of these notes have shifted from upstream dependency updates to defects in OpenWrt's own daemons. That is uncomfortable in the short term and healthy in the long term, and the pattern of same-day paired releases across both branches shows the maintainers treat the installed base as production infrastructure rather than hobbyist firmware. Device support continues accreting steadily underneath, mostly mediatek filogic and ramips targets.
◆ Prediction
Expect the 24.10 branch to receive security-only patches until the September 2026 EoL and then stop, with migration pressure toward 25.12 increasing in the notes. Further odhcpd findings are plausible given how much of the recent CVE volume traces to that one daemon.
