Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
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.

The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.

Two of the three entries are the same changelog tagged four minutes apart.
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.
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.
