+## 7.89.0
+
+### Important Changes
+
+#### Deprecations
+
+- **feat(core): Deprecate `configureScope` (#9887)**
+- **feat(core): Deprecate `pushScope` & `popScope` (#9890)**
+
+This release deprecates `configureScope`, `pushScope`, and `popScope`, which will be removed in the upcoming v8 major release.
+
+#### Hapi Integration
+
+- **feat(node): Add Hapi Integration (#9539)**
+
+This release adds an integration for Hapi. It can be used as follows:
+
+```ts
+const Sentry = require('@sentry/node');
+const Hapi = require('@hapi/hapi');
+
+const init = async () => {
+ const server = Hapi.server({
+ // your server configuration ...
+ });
+
+ Sentry.init({
+ dsn: '__DSN__',
+ tracesSampleRate: 1.0,
+ integrations: [
+ new Sentry.Integrations.Hapi({ server }),
+ ],
+ });
+
+ server.route({
+ // your route configuration ...
+ });
+
+ await server.start();
+};
+```
+
+#### SvelteKit 2.0
+
+- **chore(sveltekit): Add SvelteKit 2.0 to peer dependencies (#9861)**
+
+This release adds support for SvelteKit 2.0 in the `@sentry/sveltekit` package. If you're upgrading from SvelteKit 1.x to 2.x and already use the Sentry SvelteKit SDK, no changes apart from upgrading to this (or a newer) version are necessary.
+
+### Other Changes
+
+- feat(core): Add type & utility for function-based integrations (#9818)
+- feat(core): Update `withScope` to return callback return value (#9866)
+- feat(deno): Support `Deno.CronSchedule` for cron jobs (#9880)
+- feat(nextjs): Auto instrument generation functions (#9781)
+- feat(nextjs): Connect server component transactions if there is no incoming trace (#9845)
+- feat(node-experimental): Update to new Scope APIs (#9799)
+- feat(replay): Add `canvas.type` setting (#9877)
+- fix(nextjs): Export `createReduxEnhancer` (#9854)
+- fix(remix): Do not capture thrown redirect responses. (#9909)
+- fix(sveltekit): Add conditional exports (#9872)
+- fix(sveltekit): Avoid capturing 404 errors on client side (#9902)
+- fix(utils): Do not use `Event` type in worldwide (#9864)
+- fix(utils): Support crypto.getRandomValues in old Chromium versions (#9251)
+- fix(utils): Update `eventFromUnknownInput` to avoid scope pollution & `getCurrentHub` (#9868)
+- ref: Use `addBreadcrumb` directly & allow to pass hint (#9867)
+
+Work in this release contributed by @adam187, and @jghinestrosa. Thank you for your contributions!
+
+## 7.88.0
+
+### Important Changes
+
+- **feat(browser): Add browser metrics sdk (#9794)**
+
+The release adds alpha support for [Sentry developer metrics](https://github.com/getsentry/sentry/discussions/58584) in the Browser SDKs (`@sentry/browser` and related framework SDKs). Via the newly introduced APIs, you can now flush metrics directly to Sentry.
+
+To enable capturing metrics, you first need to add the `MetricsAggregator` integration.
+
+```js
+Sentry.init({
+ dsn: '__DSN__',
+ integrations: [
+ new Sentry.metrics.MetricsAggregator(),
+ ],
+});
+```
+
+Then you'll be able to add `counters`, `sets`, `distributions`, and `gauges` under the `Sentry.metrics` namespace.
+
+```js
+// Add 4 to a counter named `hits`
+Sentry.metrics.increment('hits', 4);
+
+// Add 2 to gauge named `parallel_requests`, tagged with `happy: "no"`
+Sentry.metrics.gauge('parallel_requests', 2, { tags: { happy: 'no' } });
+
+// Add 4.6 to a distribution named `response_time` with unit seconds
+Sentry.metrics.distribution('response_time', 4.6, { unit: 'seconds' });
+
+// Add 2 to a set named `valuable.ids`
+Sentry.metrics.set('valuable.ids', 2);
+```
+
+In a future release we'll add support for server runtimes (Node, Deno, Bun, Vercel Edge, etc.)
+
+- **feat(deno): Optionally instrument `Deno.cron` (#9808)**
+
+This releases add support for instrumenting [Deno cron's](https://deno.com/blog/cron) with [Sentry cron monitors](https://docs.sentry.io/product/crons/). This requires v1.38 of Deno run with the `--unstable` flag and the usage of the `DenoCron` Sentry integration.
+
+```ts
+// Import from the Deno registry
+import * as Sentry from "https://deno.land/x/sentry/index.mjs";
+
+Sentry.init({
+ dsn: '__DSN__',
+ integrations: [
+ new Sentry.DenoCron(),
+ ],
+});
+```
+
+### Other Changes
+
+- feat(replay): Bump `rrweb` to 2.6.0 (#9847)
+- fix(nextjs): Guard against injecting multiple times (#9807)
+- ref(remix): Bump Sentry CLI to ^2.23.0 (#9773)
+
+## 7.87.0
+
+- feat: Add top level `getCurrentScope()` method (#9800)
+- feat(replay): Bump `rrweb` to 2.5.0 (#9803)
+- feat(replay): Capture hydration error breadcrumb (#9759)
+- feat(types): Add profile envelope types (#9798)
+- fix(astro): Avoid RegExp creation during route interpolation (#9815)
+- fix(browser): Avoid importing from `./exports` (#9775)
+- fix(nextjs): Catch rejecting flushes (#9811)
+- fix(nextjs): Fix devserver CORS blockage when `assetPrefix` is defined (#9766)
+- fix(node): Capture errors in tRPC middleware (#9782)

This will let you select which updates to run, and automatically update your code. Make sure to still review all code changes!
+## Deprecate `pushScope` & `popScope` in favor of `withScope`
+
+Instead of manually pushing/popping a scope, you should use `Sentry.withScope(callback: (scope: Scope))` instead.
+
+## Deprecate `configureScope` in favor of using `getCurrentScope()`
+
+Instead of updating the scope in a callback via `configureScope()`, you should access it via `getCurrentScope()` and configure it directly:
+
+```js
+Sentry.getCurrentScope().setTag('xx', 'yy');
+```
+
## Deprecate `addGlobalEventProcessor` in favor of `addEventProcessor`
Instead of using `addGlobalEventProcessor`, you should use `addEventProcessor` which does not add the event processor globally, but to the current client.

+ *
+ * It is a singleton instance of the {@linkcode Permissions} object and is
+ * based on the web platform
+ * [Permissions API](https://developer.mozilla.org/en-US/docs/Web/API/Permissions_API),
+ * though some proposed parts of the API which are useful in a server side
+ * runtime context were removed or abandoned in the web platform specification
+ * which is why it was chosen to locate it in the {@linkcode Deno} namespace
+ * instead.
+ *
+ * By default, if the `stdin`/`stdout` is TTY for the Deno CLI (meaning it can
+ * send and receive text), then the CLI will prompt the user to grant
+ * permission when an un-granted permission is requested. This behavior can
+ * be changed by using the `--no-prompt` command at startup. When prompting
+ * the CLI will request the narrowest permission possible, potentially making
+ * it annoying to the user. The permissions APIs allow the code author to
+ * request a wider set of permissions at one time in order to provide a better
+ * user experience.
+ *
+ * Requesting already granted permissions will not prompt the user and will
+ * return that the permission was granted.
+ *
+ * ### Querying
+ *
+ * ```ts
+ * const status = await Deno.permissions.query({ name: "read", path: "/etc" });
+ * console.log(status.state);
+ * ```
+ *
+ * ```ts
+ * const status = Deno.permissions.querySync({ name: "read", path: "/etc" });

+ * ### Revoking
+ *
+ * ```ts
+ * import { assert } from "https://deno.land/std/assert/mod.ts";
+ *
+ * const status = await Deno.permissions.revoke({ name: "run" });
+ * assert(status.state !== "granted")

+ *
+ * const status = Deno.permissions.revokeSync({ name: "run" });
+ * assert(status.state !== "granted")

+ *
+ * ```ts
