OpenClaw v2026.4.15, released on April 16, 2026, promotes Anthropic's newest model to the default, adds a long-requested voice capability to the bundled Google plugin, and moves durable memory to the cloud for teams that do not want to rely on local disk.
Claude Opus 4.7 Becomes the Default
Default Anthropic model selections, the opus aliases, Claude CLI defaults, and bundled image understanding all move to Claude Opus 4.7. Users who have not explicitly pinned a model will automatically pick up the newer model on upgrade.
Gemini Text-to-Speech
The bundled google plugin gains Gemini TTS, including provider registration, voice selection, WAV reply output, PCM telephony output, and setup guidance. Agents running on Google's stack can now speak their replies without wiring a separate speech provider.
Model Auth Status Card
The Control UI Overview adds a Model Auth status card showing OAuth token health and provider rate-limit pressure at a glance, with explicit callouts when OAuth tokens are expiring or expired. The new models.authStatus gateway method strips credentials and caches for 60 seconds.
Cloud-Backed Durable Memory
LanceDB memory now supports cloud object storage, so durable memory indexes can live off local disk. Operators running agents across multiple hosts or ephemeral workers no longer have to rebuild the index on every redeploy.
Other Additions
A new GitHub Copilot embedding provider joins the memory-search stack, sharing a hardened Copilot transport helper. An experimental agents.defaults.experimental.localModelLean: true drops heavyweight default tools like browser, cron, and message to shrink prompts for weaker local-model setups. Plugin packaging localizes runtime deps to their owning extensions, trimming published build size.
Fixes
The release also patches a spurious SIGUSR1 restart loop triggered by plugin auto-enable writes on systemd, enables the unknown-tool stream guard by default, adds a TUI streaming watchdog, and hardens Matrix DM pairing, Feishu webhook signatures, and WhatsApp Baileys encrypted upload handling. Managed users on OpenClaw Launch pick up the new defaults as their instances are refreshed.
