Important Changes

• feat(aws-serverless): Ship Lambda extension in npm package for container image Lambdas (#20133)

  The Sentry Lambda extension is now included in the npm package, enabling container image-based Lambda functions to use it. Copy the extension files into your Docker image and set the tunnel option:

  RUN mkdir -p /opt/sentry-extension
  COPY node_modules/@sentry/aws-serverless/build/lambda-extension/sentry-extension /opt/extensions/sentry-extension
  COPY node_modules/@sentry/aws-serverless/build/lambda-extension/index.mjs /opt/sentry-extension/index.mjs
  RUN chmod +x /opt/extensions/sentry-extension /opt/sentry-extension/index.mjs

  Sentry.init({
    dsn: '__DSN__',
    tunnel: 'http://localhost:9000/envelope',
  });

  This works with any Sentry SDK (@sentry/aws-serverless, @sentry/sveltekit, @sentry/node, etc.).

• feat(cloudflare): Support basic WorkerEntrypoint (#19884)

  withSentry now supports instrumenting classes extending Cloudflare's WorkerEntrypoint. This instruments fetch, scheduled, queue, and tail handlers.

  import * as Sentry from '@sentry/cloudflare';
  import { WorkerEntrypoint } from 'cloudflare:workers';
  
  class MyWorker extends WorkerEntrypoint {
    async fetch(request: Request): Promise<Response> {
      return new Response('Hello World!');
    }
  }
  
  export default Sentry.withSentry(env => ({ dsn: env.SENTRY_DSN, tracesSampleRate: 1.0 }), MyWorker);

• ref(core): Unify .do* span ops to gen_ai.generate_content (#20074)

  All Vercel AI do* spans (ai.generateText.doGenerate, ai.streamText.doStream, ai.generateObject.doGenerate, ai.streamObject.doStream) now use a single unified span op gen_ai.generate_content instead of separate ops like gen_ai.generate_text, gen_ai.stream_text, gen_ai.generate_object, and gen_ai.stream_object.

• ref(core): Remove provider-specific AI span attributes in favor of gen_ai attributes in sentry conventions (#20011)

  The following provider-specific span attributes have been removed from the OpenAI and Anthropic AI integrations. Use the standardized gen_ai.* equivalents instead:

  Removed attribute	Replacement
  openai.response.id	gen_ai.response.id
  openai.response.model	gen_ai.response.model
  openai.usage.prompt_tokens	gen_ai.usage.input_tokens
  openai.usage.completion_tokens	gen_ai.usage.output_tokens
  openai.response.timestamp	(removed, no replacement)
  anthropic.response.timestamp	(removed, no replacement)

  If you reference these attributes in hooks (e.g. beforeSendTransaction), update them to the gen_ai.* equivalents.

• feat(core): Support embeddings in LangChain (#20017)

  Adds instrumentation for LangChain embeddings (embedQuery, embedDocuments), creating gen_ai.embeddings spans. In Node.js, embedding classes from @langchain/openai, @langchain/google-genai, @langchain/mistralai, and @langchain/google-vertexai are auto-instrumented. For other runtimes, use the new instrumentLangChainEmbeddings API:

  import * as Sentry from '@sentry/cloudflare';
  import { OpenAIEmbeddings } from '@langchain/openai';
  
  const embeddings = Sentry.instrumentLangChainEmbeddings(new OpenAIEmbeddings({ model: 'text-embedding-3-small' }));
  
  await embeddings.embedQuery('Hello world');
