Important Changes

• feat(react): React Router v7 support (library) (#14513)

  This release adds support for React Router v7 (library mode).
  Check out the docs on how to set up the integration: Sentry React Router v7 Integration Docs

Deprecations

• feat: Warn about source-map generation (#14533)

  In the next major version of the SDK we will change how source maps are generated when the SDK is added to an application.
  Currently, the implementation varies a lot between different SDKs and can be difficult to understand.
  Moving forward, our goal is to turn on source maps for every framework, unless we detect that they are explicitly turned off.
  Additionally, if we end up enabling source maps, we will emit a log message that we did so.

  With this particular release, we are emitting warnings that source map generation will change in the future and we print instructions on how to prepare for the next major.

• feat(nuxt): Deprecate tracingOptions in favor of vueIntegration (#14530)

  Currently it is possible to configure tracing options in two places in the Sentry Nuxt SDK:

  • In Sentry.init()
  • Inside tracingOptions in Sentry.init()

  For tree-shaking purposes and alignment with the Vue SDK, it is now recommended to instead use the newly exported vueIntegration() and its tracingOptions option to configure tracing options in the Nuxt SDK:

  // sentry.client.config.ts
  import * as Sentry from '@ sentry/nuxt';

  Sentry.init({
  // ...
  integrations: [
  Sentry.vueIntegration({
  tracingOptions: {
  trackComponents: true,
  },
  }),
  ],
  });

Important Changes

• meta(nuxt): Require minimum Nuxt v3.7.0 (#14473)

  We formalized that the Nuxt SDK is at minimum compatible with Nuxt version 3.7.0 and above.
  Additionally, the SDK requires the implicit nitropack dependency to satisfy version ^2.10.0 and ofetch to satisfy ^1.4.0.
  It is recommended to check your lock-files and manually upgrade these dependencies if they don't match the version ranges.

Deprecations

We are deprecating a few APIs which will be removed in the next major.

The following deprecations will potentially affect you:

• feat(core): Update & deprecate undefined option handling (#14450)

  In the next major version we will change how passing undefined to tracesSampleRate / tracesSampler / enableTracing will behave.

  Currently, doing the following:

  Sentry.init({
    tracesSampleRate: undefined,
  });

  Will result in tracing being enabled (although no spans will be generated) because the tracesSampleRate key is present in the options object.
  In the next major version, this behavior will be changed so that passing undefined (or rather having a tracesSampleRate key) will result in tracing being disabled, the same as not passing the option at all.
  If you are currently relying on undefined being passed, and and thus have tracing enabled, it is recommended to update your config to set e.g. tracesSampleRate: 0 instead, which will also enable tracing in v9.

  The same applies to tracesSampler and enableTracing.

• feat(core): Log warnings when returning null in beforeSendSpan (#14433)

  Currently, the beforeSendSpan option in Sentry.init() allows you to drop individual spans from a trace by returning null from the hook.
  Since this API lends itself to creating "gaps" inside traces, we decided to change how this API will work in the next major version.

  With the next major version the beforeSendSpan API can only be used to mutate spans, but no longer to drop them.
  With this release the SDK will warn you if you are using this API to drop spans.
  Instead, it is recommended to configure instrumentation (i.e. integrations) directly to control what spans are created.

  Additionally, with the next major version, root spans will also be passed to beforeSendSpan.

• feat(utils): Deprecate @ sentry/utils (#14431)

  With the next major version the @ sentry/utils package will be merged into the @ sentry/core package.
  It is therefore no longer recommended to use the @ sentry/utils package.

• feat(vue): Deprecate configuring Vue tracing options anywhere else other than through the vueIntegration's tracingOptions option (#14385)

  Currently it is possible to configure tracing options in various places in the Sentry Vue SDK:

  • In Sentry.init()
  • Inside tracingOptions in Sentry.init()
  • In the vueIntegration() options
  • Inside tracingOptions in the vueIntegration() options

  Because this is a bit messy and confusing to document, the only recommended way to configure tracing options going forward is through the tracingOptions in the vueIntegration().
  The other means of configuration will be removed in the next major version of the SDK.

• feat: Deprecate registerEsmLoaderHooks.include and registerEsmLoaderHooks.exclude (#14486)

  Currently it is possible to define registerEsmLoaderHooks.include and registerEsmLoaderHooks.exclude options in Sentry.init() to only apply ESM loader hooks to a subset of modules.
  This API served as an escape hatch in case certain modules are incompatible with ESM loader hooks.

  Since this API was introduced, a way was found to only wrap modules that there exists instrumentation for (meaning a vetted list).
  To only wrap modules that have instrumentation, it is recommended to instead set registerEsmLoaderHooks.onlyIncludeInstrumentedModules to true.

  Note that onlyIncludeInstrumentedModules: true will become the default behavior in the next major version and the registerEsmLoaderHooks will no longer accept fine-grained options.

The following deprecations will most likely not affect you unless you are building an SDK yourself:

• feat(core): Deprecate arrayify (#14405)
• feat(core): Deprecate flatten (#14454)
• feat(core): Deprecate urlEncode (#14406)
• feat(core): Deprecate validSeverityLevels (#14407)
• feat(core/utils): Deprecate getNumberOfUrlSegments (#14458)
• feat(utils): Deprecate memoBuilder, BAGGAGE_HEADER_NAME, and makeFifoCache (#14434)
• feat(utils/core): Deprecate addRequestDataToEvent and extractRequestData (#14430)

Other Changes

• feat: Streamline sentry-trace, baggage and DSC handling (#14364)
• feat(core): Further optimize debug ID parsing (#14365)
• feat(node): Add openTelemetryInstrumentations option (#14484)
• feat(nuxt): Add filter for not found source maps (devtools) (#14437)
• feat(nuxt): Only delete public source maps (#14438)
• fix(nextjs): Don't report NEXT_REDIRECT from browser (#14440)
