Resend
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
A side-by-side editorial comparison of KubeVirt and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Prowler's assistant decides what to do with findings; the patches keep the scanner honest
Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

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.
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.

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.
Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.
