## 2026.4.19-beta.2
### Fixes
- Agents/openai-completions: always send `stream_options.include_usage` on streaming requests, so local and custom OpenAI-compatible backends report real context usage instead of showing 0%. (#68746) Thanks @kagura-agent.
- Agents/nested lanes: scope nested agent work per target session so a long-running nested run on one session no longer head-of-line blocks unrelated sessions across the gateway. (#67785) Thanks @stainlu.
- Agents/status: preserve carried-forward session token totals for providers that omit usage metadata, so `/status` and `openclaw sessions` keep showing the last known context usage instead of dropping back to unknown/0%. (#67695) Thanks @stainlu.
- Install/update: keep legacy update verification compatible with the QA Lab runtime shim, so updating older global installs to beta no longer fails after npm installs the package successfully.
