OpenClaw Releases Version v2026.4.25: TTS Fully Upgraded with Support for Six New Voice Service Providers
According to the official OpenClaw GitHub release notes, OpenClaw released version v2026.4.25 on April 27. This update covers multiple core modules—including speech, plugins, observability, and browser automation—with the following key highlights:
•
TTS Overhaul: Added support for six new voice service providers—Azure Speech, Xiaomi MiMo, ElevenLabs v3, Inworld, Volcengine (Volcano Engine), and local CLI—and introduced chat-session-level automatic TTS control, TTS persona binding, and cross-Agent/account-level override configurations.
•
Plugin Registry Optimization: Migrated plugin startup and installation paths to a cold-persistent registry, reducing full-manifest scanning and improving determinism for plugin updates, fixes, and discovery.
•
OpenTelemetry Expansion: Extended coverage across the full observability pipeline—including model invocations, token usage, tool loops, Harness execution, process execution, message delivery, context assembly, and memory pressure metrics.
•
Browser Automation Enhancements: Added iframe-aware role snapshots, CDP readiness tuning, one-click headless startup, and deeper browser diagnostic probes.
•
Installation Stability Improvements: Fixed installation and update issues across Windows, macOS, Linux, and Docker platforms.
