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 Dapr?

Dapr patches three release lines at once and writes root-cause notes for each fix.

Dapr maintains 1.16, 1.17 and 1.18 concurrently, cutting patches on all three within days of each other and running a numbered release-candidate sequence on the active line. The release notes are unusually rigorous — each fix gets problem, impact, root cause and solution sections. The most recent round fixed input bindings that never activated when an application was slow to answer the subscription discovery probe, which previously had a hardcoded three-second budget, and moved builds to Go 1.26.5 for standard library vulnerabilities.

SimpleSAMLphp vs Dapr: editorial side-by-side

S0.0

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.

Dapr
DEVOPS
5.0

Dapr patches three release lines at once and writes root-cause notes for each fix.

◆ Current state

Dapr maintains 1.16, 1.17 and 1.18 concurrently, cutting patches on all three within days of each other and running a numbered release-candidate sequence on the active line. The release notes are unusually rigorous — each fix gets problem, impact, root cause and solution sections. The most recent round fixed input bindings that never activated when an application was slow to answer the subscription discovery probe, which previously had a hardcoded three-second budget, and moved builds to Go 1.26.5 for standard library vulnerabilities.

◆ Where it's heading

The current fix pattern points at applications and clusters under stress: probe timeouts too tight for JVM warmup, actor timer callbacks blocking other actors, sidecars restarting on unrelated configuration changes, workflow instance ID reuse while child workflows are still running. This is the work of a runtime being pushed by production deployments rather than one adding surface. The 1.18 line has also picked up MCP server support, visible only through registration retry and credential reload fixes.

◆ Prediction

Given the rc sequence in flight, a 1.18.3 release is imminent; the MCP server path is the newest component and the most likely source of the next round of fixes.
