What is GLAuth?

GLAuth's September releases are security dependency updates and build fixes.

GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.

What is Skipper?

Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.

Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.

0.0

GLAuth's September releases are security dependency updates and build fixes.

◆ Current state

GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.

◆ Where it's heading

GLAuth is in maintenance after 2.5.0, with occasional security and build releases. No new features have shipped since April.

◆ Prediction

Expect occasional 2.5.x security updates; the entries give no sign of the next feature release.

5.0

Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.

◆ Current state

Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.

◆ Where it's heading

Zone-aware routing is being made safe for production, with guards against skew and fixes for a data race and silent misconfiguration. It currently works only in the routesrv mode, and the release notes say the direct Kubernetes mode needs the same filtering.

◆ Prediction

Expect zone filtering to be extended to the skipper-to-Kubernetes mode in a coming tag, as the v0.28.60 notes say is needed.
