➔ kube-scheduler Module Pins and Snapshot Listers
kube-scheduler, the Kubernetes scheduler module mirror, had a quiet but useful week: dependency pins moved forward, etcd reached 3.7.0, and mutable scheduler snapshots got a cleaner interface. This is not a flashy feature week. It is the kind of maintenance that matters when you build scheduler plugins or track Kubernetes master from Go modules.
➔ Kubernetes Master Activity: PodGroup Validation and Scheduler Fixes
Kubernetes is the container orchestration project most teams meet through clusters, but this week the interesting work is in the machinery behind new scheduling APIs. The master branch activity is worth reading if you build controllers, scheduler plugins, or clients against alpha APIs. The headline is PodGroup policy work, with preemptionPolicy, workloadRef, and broader declarative validation all moving at once.
➔ Kubernetes v1.35.6 Release - Critical CSI Fix and Go Update
Kubernetes v1.35.6 arrived on June 12, 2026, as a standard patch release for the current stable branch. This update is particularly important for clusters using CSI drivers due to a bug that could lead to stale volume data. It also updates the build environment to Go 1.25.11 and addresses several panics in the scheduler and networking components.
➔ Apache Airflow this week, multi team triggerer and dags clear CLI
Apache Airflow shipped 143 commits to main in the last seven days, touching 1,210 files across 46,490 insertions and 11,241 deletions. The headline change is multi team triggerer support landing as a schema migration on the trigger table, plus a new airflow dags clear CLI for partition range reprocessing. This post walks the activity that actually matters for operators and DAG authors who follow apache/airflow.
