OpenClaw v2026.4.19-beta.2 Fixes Session Scoping and Streaming Context Usage

OpenClaw’s April 19th patch release, v2026.4.19-beta.2, landed several important bug fixes focused on session reliability and accurate usage reporting.

Key fixes:

  • Streaming usage reporting — stream_options.include_usage is now always sent on streaming requests, so local and custom OpenAI-compatible backends report real context usage instead of showing 0%
  • Nested agent lane scoping — nested agent work is now scoped per target session, fixing a bug where a long-running nested run on one session could head-of-line block unrelated sessions across the gateway
  • Token total preservation — session token totals are carried forward even when providers omit usage metadata, so /status and openclaw sessions keep showing the last known context instead of dropping to unknown/0%
  • Install/update — legacy update verification now stays compatible with the QA Lab runtime shim, so updating older global installs to beta no longer fails after npm install completes
