braintrust@3.17.0

braintrust

3.17.0

Minor Changes

• feat: ship the bt CLI with the SDK. Installing braintrust now exposes a bt command in node_modules/.bin that runs the prebuilt native binary for your platform (delivered via @braintrust/bt-* optional dependencies). If optional dependencies are skipped (e.g. --no-optional / --omit=optional), a postinstall script downloads the matching binary from the npm registry as a fallback. (#2067)

braintrust@3.16.0

braintrust

3.16.0

Minor Changes

• feat: Export LocalTrace (#2088)
• feat(invoke): Allow passing overrides to invoke() (#2087)

Patch Changes

• fix(stream): Preserve multi-byte UTF-8 split across chunk boundaries (#2091)
• fix: Don't have output in dataset pipeline row type definition (#2089)

braintrust@3.15.0

braintrust

3.15.0

Attention: This release is technically a breaking change because it removes the wrapFlueContext, and wrapFlueSession exports for @flue/runtime. This release was still deemed as a minor because of the experimental state of flue and limited adoption of @flue/runtime instrumentation.

• feat(flue): Update flue instrumentation to use new observe hooks (#2070)

braintrust@3.14.0

braintrust

3.14.0

Minor Changes

• feat(mastra): Add Mastra auto-instrumentation (#1901)
