OpenClaw 2026.9.34 is an extended-stable release, the project's equivalent of LTS, based on the late-September code with critical security updates, reliability fixes and support for new models. Its headline change makes apply_patch validate the whole set of edits before touching the workspace, so a bad later step can no longer delete files changed earlier.
Anthropic's open-source sandbox-runtime, the sandbox used by Claude Code, limits file and network access for agents, MCP servers and command-line tools. It relies on Seatbelt on macOS and bubblewrap on Linux rather than containers.
A tutorial shows how to build an engineering copilot with Letta whose memory goes beyond the prompt. It covers inspectable core memory, vector-based archival retrieval, state shared between agents, custom tools and portable workflows.
TechCrunch has compiled a list of notable AI agents that work through text messaging, ranging from general assistants to agents built for families, travel and work.
Google has made Data Agent Kit generally available: a free set of MCP tools and 37 open-source skills that connect coding agents to more than fifteen Google Data Cloud services. It ships two kinds of guardrail, one where a skill asks the agent to stop and one where an IAM deny policy blocks the call outright.
Google says an unattended 11-hour run of Gemini 4 Argon produced two accepted optimisations to its Agent Development Kit codebase. They cut in-memory session preparation overhead by about 40% in long sessions and cold package import time by 21%.
