What is Ably?

Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.

Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.

What is KubeArmor?

KubeArmor is hardening its eBPF DNS visibility and supply chain security posture in the v1.7.5 pre-release cycle.

KubeArmor is in active pre-release for v1.7.5, having shipped three release candidates. The rc1 switched the BPF hook for DNS traffic from udp_sendmsg to udp_send_skb — a kernel-level change that captures DNS at the correct interception point for accurate visibility. The rc2 added SLSA Level 3 provenance, isolated container builds, and improved OpenSSF Scorecard compliance to the project's build and release pipeline. Support for Ubuntu 26.04, openEuler 24.03 LTS-SP3, and kernel 6.17 DNS tracking arrived in the 1.7.4-rc3 cycle.

7.5

Ably ships LiveObjects as production-ready and expands its AI Transport SDK to cover Temporal durable workflows.

◆ Current state

Ably is shipping simultaneously across infrastructure SDKs and AI-specific capabilities. LiveObjects — a real-time state sync layer for nested maps and counters — graduated from experimental to production-stable in the Java and Cocoa SDKs this month, with path-based access and resilient subscriptions that survive underlying object replacement. The AI Transport SDK gained Temporal durable-workflow support and OpenAI Responses API streaming. On the infrastructure side, the .NET SDK reduces reconnect latency from 120s to ~25s and the Terraform provider got a major maturity pass with moderation rules and a config importer.

◆ Where it's heading

The direction is Ably as AI agent infrastructure. LiveObjects' own documentation positions it explicitly for 'AI agents, live configurations, and collaborative experiences.' The AI Transport SDK is a purpose-built layer for agentic workflows — durable sessions, multi-turn conversations, tool execution — layered on Ably's realtime primitives. This is a deliberate expansion from realtime messaging platform into the transport layer that agents run on.

◆ Prediction

The AI Transport SDK will add more model provider codecs — the OpenAI Responses integration suggests Anthropic or Gemini support is next. LiveObjects needs to reach stable across remaining SDKs (Python, .NET) before the feature can be adopted uniformly.

5.0

KubeArmor is hardening its eBPF DNS visibility and supply chain security posture in the v1.7.5 pre-release cycle.

◆ Current state

KubeArmor is in active pre-release for v1.7.5, having shipped three release candidates. The rc1 switched the BPF hook for DNS traffic from udp_sendmsg to udp_send_skb — a kernel-level change that captures DNS at the correct interception point for accurate visibility. The rc2 added SLSA Level 3 provenance, isolated container builds, and improved OpenSSF Scorecard compliance to the project's build and release pipeline. Support for Ubuntu 26.04, openEuler 24.03 LTS-SP3, and kernel 6.17 DNS tracking arrived in the 1.7.4-rc3 cycle.

◆ Where it's heading

KubeArmor is running two parallel improvement tracks: eBPF policy enforcement quality (BPF hook changes, quota handling via NPE, hostname/TLD matching improvements) and supply chain security compliance (SLSA, Scorecard, pinned dependencies, isolated builds). The latter is increasingly a table-stakes requirement for enterprise Kubernetes security teams auditing their toolchain, not a differentiator. New kernel and OS support signals broadening the deployment surface — particularly for regulated environments with specific OS requirements.

◆ Prediction

v1.7.5 stable will ship shortly given three RCs already published. The eBPF DNS visibility change enables syscall-level DNS auditing for workloads that need it; the SLSA Level 3 provenance will be cited in enterprise security reviews as a prerequisite for adoption.
