TechFlow News, April 27: 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 synthesis, plugins, observability, and browser automation—with the following key highlights:
- Comprehensive TTS Upgrade: Added support for six speech service providers—Azure Speech, Xiaomi MiMo, ElevenLabs v3, Inworld, VolcEngine (Volcano Engine), and local CLI—and introduced chat-session-level automatic TTS control, TTS personas binding, and cross-Agent/account-level override configuration.
- Plugin Registry Optimization: Migrated plugin startup and installation paths to a cold-persistent registry, reducing full-manifest scanning and improving determinism in plugin updates, fixes, and discovery.
- OpenTelemetry Expansion: Extended telemetry coverage across the full stack—including model invocations, token usage, tool loops, Harness execution, process execution, message delivery, context assembly, and memory pressure metrics.
- Enhanced Browser Automation: Added iframe-aware role snapshots, CDP readiness tuning, one-click headless startup, and deeper browser diagnostic probes.
- Improved Installation Stability: Fixed installation and update issues across Windows, macOS, Linux, and Docker platforms—including LaunchAgent token rotation and hybrid-version gateway validation.
