## [1.3.0] - Unreleased
## [1.3.0] - 2026-11-06

### Added
- **Zero-code instrumentation:** `node --require traceperf/auto app.js` (or `--import` for ESM). Every incoming HTTP request is a top-level call with outgoing `http`/`fetch` calls and `pg`, `mysql2`, MongoDB/Mongoose and `ioredis` queries nested under it; database clients are instrumented only when the app's `package.json` lists them. Configured with `TRACEPERF_*` environment variables; prints statistics and explanations on exit. In code: `autoInstrument(tp)`.

### Development
- CI runs a MySQL 8.4 service for the driver tests. The packed-package check runs `node --require traceperf/auto` on every Node version from 14 to 24.

## [1.2.0] - Unreleased
## [1.2.0] - not published separately (released in 1.3.0)

### Added
- **Database and cloud clients:** `instrumentPg`, `instrumentMysql2`, `instrumentMongo` (also works for Mongoose via `mongoose.mongo`), `instrumentRedis` (ioredis) and `instrumentAwsClient` (AWS SDK v3). Labels look like `pg SELECT users` or `aws S3.GetObject`. `sqlLabel()` builds low-cardinality SQL labels.

## [1.1.0] - Unreleased
## [1.1.0] - not published separately (released in 1.3.0)

### Added
- **OpenTelemetry live mode:** `openTelemetryExporter(api, { live: true })` opens each span when the call starts and keeps it active while the call runs (across `await`). Spans from other instrumentation (database drivers, HTTP clients) then nest under traceperf's spans.

### Added
- **Results API:** `onComplete(listener)` and `use(plugin)` (`onStart`/`onComplete` hooks) receive every finished call tree as an `ExecutionRecord` (ms: duration, self time, sync time, heap delta, error, args, children). A plugin that throws is reported once and never breaks the tracked code. A `reporter` option replaces console output, and `formatTree()` renders the default output.

## [0.2.2] - not published separately (released in 1.3.0)

### Fixed
- `import 'traceperf'` (ESM) failed with `ERR_MODULE_NOT_FOUND`. The ESM build is now real ESM (explicit `.js` extensions, `"type": "module"` scope) and no longer contains a `module.exports` shim that bundlers reject.
