What is OpenKruise?
Seven workload APIs graduated to beta — then the feed went quiet for six months.
OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.
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.

OpenKruise
0.0INFRA · APIS
Seven workload APIs graduated to beta — then the feed went quiet for six months.
◆ Current state
OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.
◆ Where it's heading
This is a project consolidating rather than expanding — graduating APIs to beta is a commitment to stop changing their shape, and the accompanying features fill gaps in existing controllers rather than adding new ones. The pod resize protection is the one forward-looking item, tracking in-place resource resizing as it stabilizes upstream in Kubernetes. Whether the v1.9.0 line ever reached a stable release is not visible here.
◆ Prediction
The obvious next step is a stable v1.9.0 with the v1beta1 APIs finalized. The six-month gap since the last alpha is worth verifying against the project's actual release activity before reading it as a slowdown.
WorkOS
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.
