Voicebox Service Release Notes

The Voicebox Service is released independently of Launchpad.

All available releases of the Voicebox Service are listed below. The image tag for a release is simply the release name prepended with v as in v0.1.1.

1.0.0 Release (August 28, 2026)

• Answer complex, multi-step questions by planning and running a sequence of queries against Stardog, rather than translating a question into a single query
• Reason across multiple steps on every question. Think Mode is no longer a separate mode and its toggle no longer applies
• Build on earlier turns in a conversation: results are kept and reused, so a follow-up question can refine or analyze a previous answer without re-querying Stardog
• Analyze returned results as part of answering, rather than only returning the table
• Return a summary of what was attempted when a question is too complex to finish, instead of a generic “cannot find an answer” response
• Choose where results are persisted — local disk or Amazon S3 — so the service can scale beyond a single instance. See Frame Stores

1.0.0-beta.3 Release (July 29, 2026)

This is a beta build of the next-generation Voicebox Service, distributed under the v1.0.0-beta.3 tag. It powers the Launchpad public API beta and runs alongside the stable 0.x service. See Deploying the Voicebox Service for deployment details.

• Answer questions faster by loading matching example queries up front, and answer immediately when a question exactly matches a saved query
• Return a summary of what was attempted when a question is too complex to finish, instead of a generic “cannot find an answer” response
• Fix intermittent authentication errors when answering questions against a knowledge graph whose cached schema outlived the token that loaded it
• Add VOICEBOX_QUERY_EXEC_TIMEOUT_SECONDS (default: 60), VOICEBOX_QUERY_MAX_RESULTS (default: 100000), and VOICEBOX_RECURSION_LIMIT (default: unset) to tune query execution limits and the agent step cap
• Update dependencies to address reported CVEs

0.30.1 Release (Jul 21, 2026)

• Do not store expired tokens in the schema cache

1.0.0-beta.2 Release (July 8, 2026)

This is a beta build of the next-generation Voicebox Service, distributed under the v1.0.0-beta.2 tag. It powers the Launchpad public API beta and runs alongside the stable 0.x service. See Deploying the Voicebox Service for deployment details.

• Fix an error when answering questions against knowledge graphs where a relationship is mapped from multiple source columns
• Pick up republished or edited knowledge graph schemas immediately instead of serving a cached schema for up to an hour
• Fix an error when a question returned results with too many columns to summarize; these questions now complete successfully
• Add VOICEBOX_CODE_EXEC_TIMEOUT_SECONDS (default: 30) to configure how long the service may spend analyzing query results while answering a question, and add per-run telemetry for code execution
• Emit error tracebacks as structured log events instead of plain-text stack traces

1.0.0-beta.1 Release (June 30, 2026)

This is a beta build of the next-generation Voicebox Service, distributed under the v1.0.0-beta.1 tag. It powers the Launchpad public API beta and runs alongside the stable 0.x service. See Deploying the Voicebox Service for deployment details.
