 ### Key Rules

 - **All PRs target `develop` branch** (NOT `master`)
 - `master` represents the last released state
 - Never merge directly into `master` (except emergency fixes)
 - Avoid changing `package.json` files on `develop` during pending releases
+- Never update dependencies, package.json content or build scripts unless explicitly asked for
+- When asked to do a task on a set of files, always make sure that all occurences in the codebase are covered. Double check that no files have been forgotten.
+- Unless explicitly asked for, make sure to cover all files, including files in `src/` and `test/` directories.

 ## Development Guidelines
 
 ### Build System
+
 - Uses Rollup for bundling (`rollup.*.config.mjs`)
 - TypeScript with multiple tsconfig files per package
 - Lerna manages package dependencies and publishing
 - Vite for testing with `vitest`
 
 ### Package Structure Pattern
+
 Each package typically contains:
+
 - `src/index.ts` - Main entry point
 - `src/sdk.ts` - SDK initialization logic
 - `rollup.npm.config.mjs` - Build configuration
 - `tsconfig.json`, `tsconfig.test.json`, `tsconfig.types.json`
 - `test/` directory with corresponding test files
 
 ### Key Development Notes
+
 - Uses Volta for Node.js/Yarn version management
 - Requires initial `yarn build` after `yarn install` for TypeScript linking
 - Integration tests use Playwright extensively
-- Native profiling requires Python <3.12 for binary builds
+- Never change the volta, yarn, or package manager setup in general unless explicitly asked for
+
+### Notes for Background Tasks
+
+- Make sure to use [volta](https://volta.sh/) for development. Volta is used to manage the node, yarn and pnpm version used.
+- Make sure that [PNPM support is enabled in volta](https://docs.volta.sh/advanced/pnpm). This means that the `VOLTA_FEATURE_PNPM` environment variable has to be set to `1`.
+- Yarn, Node and PNPM have to be used through volta, in the versions defined by the volta config. NEVER change any versions unless explicitly asked to.
 
 ## Testing Single Packages
+
 - Test specific package: `cd packages/{package-name} && yarn test`
 - Build specific package: `yarn build:dev:filter @sentry/{package-name}`
 
 ## Code Style Rules
+
 - Follow existing code conventions in each package
 - Check imports and dependencies - only use libraries already in the codebase
 - Look at neighboring files for patterns and style
 - Never introduce code that exposes secrets or keys
 - Follow security best practices
 
 ## Before Every Commit Checklist
+
 1. ✅ `yarn lint` (fix all issues)
 2. ✅ `yarn test` (all tests pass)
 3. ✅ `yarn build:dev` (builds successfully)
 4. ✅ Target `develop` branch for PRs (not `master`)

+### Important Changes
+
+- **feat(browser): Add debugId sync APIs between web worker and main thread ([#16981](https://github.com/getsentry/sentry-javascript/pull/16981))**
+
+This release adds two Browser SDK APIs to let the main thread know about debugIds of worker files:
+
+- `webWorkerIntegration({worker})` to be used in the main thread
+- `registerWebWorker({self})` to be used in the web worker
+
+```js
+// main.js
+Sentry.init({...})
+
+const worker = new MyWorker(...);
+
+Sentry.addIntegration(Sentry.webWorkerIntegration({ worker }));
+
+worker.addEventListener('message', e => {...});
+```
+
+```js
+// worker.js
+Sentry.registerWebWorker({ self });
+
+self.postMessage(...);
+```
+
+- **feat(core): Deprecate logger in favor of debug ([#17040](https://github.com/getsentry/sentry-javascript/pull/17040))**
+
+The internal SDK `logger` export from `@sentry/core` has been deprecated in favor of the `debug` export. `debug` only exposes `log`, `warn`, and `error` methods but is otherwise identical to `logger`. Note that this deprecation does not affect the `logger` export from other packages (like `@sentry/browser` or `@sentry/node`) which is used for Sentry Logging.
+
+```js
+import { logger, debug } from '@sentry/core';
+
+// before
+logger.info('This is an info message');
+
+// after
+debug.log('This is an info message');
+```
+
+- **feat(node): Add OpenAI integration ([#17022](https://github.com/getsentry/sentry-javascript/pull/17022))**
+
+This release adds official support for instrumenting OpenAI SDK calls in with Sentry tracing, following OpenTelemetry semantic conventions for Generative AI. It instruments:
+
+- `client.chat.completions.create()` - For chat-based completions
+- `client.responses.create()` - For the responses API
+
+```js
+// The integration respects your `sendDefaultPii` option, but you can override the behavior in the integration options
+
+Sentry.init({
+  dsn: '__DSN__',
+  integrations: [
+    Sentry.openAIIntegration({
+      recordInputs: true, // Force recording prompts
+      recordOutputs: true, // Force recording responses
+    }),
+  ],
+});
+```
+
+### Other Changes
+
+- feat(node-core): Expand `@opentelemetry/instrumentation` range to cover `0.203.0` ([#17043](https://github.com/getsentry/sentry-javascript/pull/17043))
+- fix(cloudflare): Ensure errors get captured from durable objects ([#16838](https://github.com/getsentry/sentry-javascript/pull/16838))
+- fix(sveltekit): Ensure server errors from streamed responses are sent ([#17044](https://github.com/getsentry/sentry-javascript/pull/17044))
