OpenClaw v2026.5.28 released, strengthens Codex recovery and launches iOS Pro UI According to Beating monitoring, the open-source AI personal assistant OpenClaw has released version 2026.5.28, which focuses on refactoring the elastic recovery mechanism of Codex and Agent runtime, and launching a new iOS development version Pro UI. In the new version, the running path of the sub agent is strictly physically isolated from the workspace to prevent sandbox contamination. System level hooks are limited to the context of prompt words and automatically release session locks upon execution timeout or active termination, while retaining framework level survival locks. In order to cope with underlying service crashes, the new version has adjusted the fault tolerance logic of the Codex application server to ensure that the failure of auxiliary processes will not drag down the shared runtime state, and completely eliminate the event cycle self-locking problem caused by historical restart residues. The mobile and chat interaction interface has received significant updates. As a mobile node client that connects iPhone hardware capabilities to the Gateway gateway, the iOS development version application (iOS node app) has undergone a comprehensive restructuring, launching a new Pro interface that integrates professional commands, intelligent agent management, real-time diagnostics, and global settings. The new version of the iOS app supports rendering remote canvases (Canvas) and adaptive interactive interfaces (A2UI) through WKWebView, and enables real-time two-way playback of Talk voice based on gateway sessions. In order to maintain communication in mobile scenarios such as network disconnection or background wake-up, the system has optimized the gateway chat transmission protocol and maintained the WebChat reconnection state. The official release has enabled the APNs wake-up mechanism based on hosted external push relay (ios push relay. openclaw. ai) by default, which ensures the security of production certificates while achieving second level background wake-up. In terms of ecological compatibility and underlying capabilities, the new version has expanded the model and document support boundaries. The system natively integrates Claude Opus 4.8 and supports Fal Krea image mode architecture, NVIDIA recommended model directory, and MiniMax music streaming response. In terms of security defense, CLI and diagnostic modules have introduced stricter dotenv security policies. When performing diagnostics or running CLI, the system will strictly ignore the. env environment variable file in the workspace directory to prevent malicious open source projects from stealing developers' cloud service credentials through local injection. In addition, the file extraction module has officially launched the ClawPDF engine, achieving for the first time structured text extraction of encrypted PDF documents and supporting direct output of structured MCP content in the results of intelligent tools.
