Stable v2026.4.15 ships as the headline upgrade target

OpenClaw Daily Brief

1. Stable v2026.4.15 is the headline ship: OpenClaw published openclaw 2026.4.15 as a non-prerelease tag on 2026-04-16, so operators can treat it as the current upgrade target without the prerelease caveats that often apply to beta lines.
2. Anthropic defaults now center on Opus 4.7 for bundled multimodal: The release retunes default Anthropic selections, opus aliases, Claude CLI defaults, and routes bundled image understanding through Claude Opus 4.7, which matters if your workflows depend on the default model stack for vision-heavy tasks.
3. Gemini text-to-speech arrives in the bundled google plugin: The same release adds Gemini TTS to that plugin (provider registration, voice pickers, WAV replies, PCM telephony output, and setup/docs), expanding voice output options without bolting on a separate TTS stack first.
4. Long sessions get cheaper prompts and bounded memory reads by default: Startup/skills prompt budgets are trimmed, memory_get excerpts are capped with explicit continuation metadata, and QMD reads follow the same bounded contract—operators running always-on agents should expect less default context volume and more deterministic continuation reads instead of silent giant pulls.
5. Hardening worth auditing this week: The gateway now rejects client tool definitions whose names normalize-collide with built-ins or with each other (400 on JSON and SSE) and tightens trusted local MEDIA: passthrough; separately, stale openai-codex transport metadata self-heals to the canonical Codex route so requests stop falling through broken HTML/Cloudflare paths—if you use Codex or custom tool names, upgrade then run one end-to-end tool call plus a media-heavy reply to confirm behavior.
