If you reference these attributes in custom instrumentation, `beforeSendSpan`, dashboards, or alerts, update them to the new names.

### Span operation (`op`) changes

Affected SDKs: All SDKs.

Span ops are now aligned to a smaller, framework-neutral, convention-backed set. The detail that used to live in the op (framework, library, method name, trigger, or lifecycle phase) is preserved in span attributes such as `code.function.name`, `sentry.origin`, `db.system.name`, `db.operation.name`, `faas.trigger`, and framework-specific attributes.

These changes are not caught by TypeScript. If you filter, group, or alert on span ops — in dashboards, dynamic sampling rules, `ignoreSpans`, or `beforeSendSpan` — update them to the new ops below.

**Backend HTTP, handlers, middleware & routers:**

| Area | Before | After |

| Hapi server extensions | `server.ext.hapi` | `middleware` |
| NestJS setup & lifecycle handlers | `app_creation.nestjs`, `request_context.nestjs`, `event.nestjs` | `function` |

**Framework functions:**

If you reference these attributes in custom instrumentation, `beforeSendSpan`, dashboards, or alerts, update them to the new names.

### Span operation (`op`) changes

Affected SDKs: All SDKs.

Span ops are now aligned to a smaller, framework-neutral, convention-backed set. The detail that used to live in the op (framework, library, method name, trigger, or lifecycle phase) is preserved in span attributes such as `code.function.name`, `sentry.origin`, `db.system.name`, `db.operation.name`, `faas.trigger`, and framework-specific attributes.

These changes are not caught by TypeScript. If you filter, group, or alert on span ops — in dashboards, dynamic sampling rules, `ignoreSpans`, or `beforeSendSpan` — update them to the new ops below.

If you reference these attributes in custom instrumentation, `beforeSendSpan`, dashboards, or alerts, update them to the new names.

### Span operation (`op`) changes

Affected SDKs: All SDKs.

Span ops are now aligned to a smaller, framework-neutral, convention-backed set. The detail that used to live in the op (framework, library, method name, trigger, or lifecycle phase) is preserved in span attributes such as `code.function.name`, `sentry.origin`, `db.system.name`, `db.operation.name`, `faas.trigger`, and framework-specific attributes.

These changes are not caught by TypeScript. If you filter, group, or alert on span ops — in dashboards, dynamic sampling rules, `ignoreSpans`, or `beforeSendSpan` — update them to the new ops below.

**Backend HTTP, handlers, middleware & routers:**

| Area | Before | After |
| -------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------- |
| Request handlers (Express, Koa, Connect, Fastify, Elysia, NestJS, …) | `request_handler.<library>`, `handler.nestjs` | `handler` |
| Hono `app.request()` in-process dispatch | `hono.request` | `http.server` |
| Web-server middleware | `middleware.express`, `middleware.koa`, `middleware.hono`, `middleware.elysia`, `middleware.nestjs`, `middleware.nuxt`, `middleware.nitro`, `middleware.tanstackstart`, `hook.fastify`, `http.server.middleware` (Next.js) | `middleware` |

**Framework functions:**

| Angular tracing decorators | `ui.angular.init` (`TraceDirective`/`TraceClass`), `ui.angular.<method>` (`TraceMethod`) | `ui.mount`, `function` |
| Ember route hooks, runloop & components | `ui.ember.route.<hook>`, `ui.ember.runloop.<queue>`, `ui.ember.component.render`/`definition`/`init` | `function`, `ui.task`, `ui.render`/`function`/`ui.mount` |
| Browser paint entries | `paint` | `browser.paint` |

**Databases, cache & messaging:**

| Kafka, AMQP & OTel-inferred messaging | `message`, `message.produce`, `message.consume` | `queue.publish`, `queue.receive`, `queue.process` |

**RPC & Gen AI:**

| GCP gRPC calls | `grpc.<service>` | `grpc` |

| GCP HTTP client | `http.client.<service>` | `http.client` |
