What is KubeVirt?
KubeVirt's 1.9 cycle is a bet on GPUs and cross-architecture VMs
Everything in the window belongs to one long v1.9.0 pre-release cycle — alpha.0 in May through rc.2 in late July — totaling roughly 1,650 changes from over 100 contributors. The release notes are cumulative, so each RC restates the prior list and appends what landed since. There is no stable v1.9.0 tag yet.
What is Rootly?
Rootly's AI stops summarizing incidents and starts investigating them
Rootly's newest release lets its AI pull evidence directly from observability, code, infrastructure, feature flag, ticketing and documentation tools, over read-only connections that store nothing. That follows the agent moving into the web app as a chat panel on every incident, and retrospective templates whose AI blocks draft from incident data, Slack and call transcripts with every prompt and source visible. The on-call side is quieter: a sidebar widget, 24-hour time, a customizable alerts table, and a one-command setup that pages your phone to prove it worked.

KubeVirt's 1.9 cycle is a bet on GPUs and cross-architecture VMs
◆ Current state
Everything in the window belongs to one long v1.9.0 pre-release cycle — alpha.0 in May through rc.2 in late July — totaling roughly 1,650 changes from over 100 contributors. The release notes are cumulative, so each RC restates the prior list and appends what landed since. There is no stable v1.9.0 tag yet.
◆ Where it's heading
The cycle's center of gravity is accelerator and device virtualization. NVIDIA Grace GPU passthrough arrives behind a feature gate with SMMUv3/IOMMUFD, ACPI Generic Initiator NUMA topology and PCI 64-bit hole sizing; GPUsWithDRA and HostDevicesWithDRA graduate to beta with E2E coverage; SR-IOV vGPU gains display support and a new metric correlates GPU UUIDs with VMIs. A second thread pushes the hardware envelope elsewhere: cross-architecture execution behind an alpha gate, workload SEV encryption to beta, and zstd compression for live-migration streams.
◆ Prediction
A stable v1.9.0 should follow shortly given rc.2 landed in late July and the recent commits are bug fixes rather than new gates. The alpha gates introduced here — cross-architecture virtualization and Grace I/O virtualization — are the ones to watch for graduation in the 1.10 cycle.

Rootly's AI stops summarizing incidents and starts investigating them
◆ Current state
Rootly's newest release lets its AI pull evidence directly from observability, code, infrastructure, feature flag, ticketing and documentation tools, over read-only connections that store nothing. That follows the agent moving into the web app as a chat panel on every incident, and retrospective templates whose AI blocks draft from incident data, Slack and call transcripts with every prompt and source visible. The on-call side is quieter: a sidebar widget, 24-hour time, a customizable alerts table, and a one-command setup that pages your phone to prove it worked.
◆ Where it's heading
Rootly is building an agent that does the first pass of an investigation rather than writing it up afterward. The consistent design choice is auditability — read-only connections, nothing retained, prompts and sources shown inside the retrospective draft — which is the precondition for letting software touch a live incident. Syncing the Cortex catalog points the same way: the agent reasons from current service ownership instead of a stale wiki.
◆ Prediction
Expect evidence gathering to start producing a ranked hypothesis or a suggested next action, since the connectors now cover everything a human would read during first triage.
