Over the past three weeks, the OpenClaw project has demonstrated remarkable agility, iterating at a pace of nearly one version every two days. This rapid development has fueled advancements across model ecosystems, omnichannel experiences, multi-agent collaboration, and security enhancements. Notably, OpenClaw has made significant strides within the iOS ecosystem: the iOS node app Alpha version was released on February 9, enabling mobile access; on February 17, iOS share extensions were introduced, allowing users to send content to AI assistants via the system share menu; on February 19, an Apple Watch companion app was launched, facilitating notification send and receive (sending and receiving) and operational approvals; and on February 21, the bridging mechanism between the watch and main app was optimized, refining voice output logic to minimize accidental triggers. In terms of architecture, OpenClaw introduced nested sub-agents for the first time on February 15, enabling sub-agents to generate their own sub-agents. The system controls depth through the maxSpawnDepth parameter, limiting each agent to a maximum of five child nodes. Additionally, depth-aware tool strategies and announce linkages were implemented, empowering OpenClaw to handle complex, multi-level tasks. Regarding model integration, OpenClaw adheres to a model-neutral strategy. On February 6, it added support for Anthropic Opus 4.6 and xAIGrok; on February 9, Grok's web search capabilities went live; on February 13, Hugging Face Inference and vLLM were integrated; on February 17, Anthropic Sonnet 4.6 was supported and Anthropic's 1 million token context beta was launched; and on February 21, the Google Gemini 3.1 Pro preview version was integrated, allowing users to flexibly switch between models such as Claude, GPT, Gemini, and Grok based on task requirements. Furthermore, OpenClaw has focused on refining details and enhancing security, such as introducing native single-message streaming output on Slack, implementing timed tasks to prevent duplicate triggers, and addressing security vulnerabilities in dependencies.
