OpenClaw has released version v2026.4.25, introducing significant upgrades across its core modules. The latest update enhances text-to-speech (TTS) capabilities by integrating six new voice service providers: Azure Speech, Xiaomi MiMo, ElevenLabs v3, Inworld, Volcengine, and a local CLI. Additionally, it introduces automatic TTS control at the chat session level and TTS personas binding, along with cross-agent and account-level configuration. The update also optimizes the plugin registry by migrating startup and installation paths to a cold persistent registry, improving the certainty of plugin updates and repairs. OpenTelemetry extensions now cover a comprehensive range of observability metrics, including model calls and memory pressure. Browser automation enhancements include iframe-aware role snapshots and deeper diagnostic probes. Installation stability has been improved across Windows, macOS, Linux, and Docker platforms.
