What is Skipper?
Zalando's ingress proxy finally speaks HTTP/2 cleartext end to end
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.
What is WorkOS?
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

◆ Current state
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.
◆ Where it's heading
The release cadence is a stream of small, individually unremarkable tags where the occasional protocol or load-balancing change is the only thing worth reading. Recent substance has clustered on the data path: leastRequests balancing in v0.27.53, h2c now. The auth filters are being maintained rather than extended, with fixes rather than new capability.
◆ Prediction
Expect the h2c work to generate follow-up fixes as it meets real gRPC backends, since the release notes already show HTTP Upgrade negotiation failing while direct prior knowledge works.

8.8INFRA · APIS
WorkOS is building identity for agents while quietly fixing the sign-up funnel.
◆ Current state
WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.
◆ Where it's heading
The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.
◆ Prediction
Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
