v0.4.0

Changelog

• d0803c3 chore: release v0.4.0 (#61)
• 4bedb0e feat!: split trace/contrib integrations into individual Go modules (#49)

This release contains breaking changes if you were using trace integrations with the Go SDK. See below on how to upgrade.

Upgrade Guide

Tracing integrations under trace/contrib/... are now published as separate Go modules instead of being transitively included by the root SDK module. This reduces unnecessary dependencies for users who only need the core SDK or a small number of integrations.

Who is affected

You only need to take action if your project uses one or more tracing integrations, for example:

• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/openai
• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/anthropic
• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/genai
• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/genkit
• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/adk
• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/langchaingo
• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/cloudwego/eino
• github.com/braintrustdata/braintrust-sdk-go/trace/contrib/github.com/sashabaranov/go-openai

If you only use the core SDK (braintrust, eval, API client, etc.), no migration is required beyond upgrading the root module.

What stays the same

• Import paths do not change
• Application code usually does not need to change
• Only the module/dependency setup changes

How to upgrade

Core SDK only

go get github.com/braintrustdata/braintrust-sdk-go@v0.4.0
go mod tidy

Core SDK + specific integrations

Install the root SDK plus each integration you use:

go get github.com/braintrustdata/braintrust-sdk-go@v0.4.0
go get github.com/braintrustdata/braintrust-sdk-go/trace/contrib/openai@v0.4.0
go get github.com/braintrustdata/braintrust-sdk-go/trace/contrib/anthropic@v0.4.0
go mod tidy

If you want the previous “install everything” behavior

Use the new convenience meta-module:

go get github.com/braintrustdata/braintrust-sdk-go/trace/contrib/all@v0.4.0
go mod tidy

This is especially useful for Orchestrion-based auto-instrumentation:

import (
    _ "github.com/DataDog/orchestrion"
    _ "github.com/braintrustdata/braintrust-sdk-go/trace/contrib/all"
)

Before vs after

Before

A single dependency pulled in all integrations transitively:

go get github.com/braintrustdata/braintrust-sdk-go

After

Install the root SDK plus only the integrations you use:

go get github.com/braintrustdata/braintrust-sdk-go
go get github.com/braintrustdata/braintrust-sdk-go/trace/contrib/openai

Or opt into all integrations explicitly:

go get github.com/braintrustdata/braintrust-sdk-go/trace/contrib/all
