- Add session replay id to Sentry Logs ([#4740](https://github.com/getsentry/sentry-java/pull/4740))
- Add support for continuous profiling of JVM applications on macOS and Linux ([#4556](https://github.com/getsentry/sentry-java/pull/4556))
- Sentry continuous profiling on the JVM is using async-profiler under the hood.
- [Sentry continuous profiling](https://docs.sentry.io/product/explore/profiling/) on the JVM is using async-profiler under the hood.
- By default this feature is disabled. Set a profile sample rate and chose a lifecycle (see below) to enable it.
- Add the `sentry-async-profiler` dependency to your project
- Set a sample rate for profiles, e.g. `1.0` to send all of them. You may use `options.setProfileSessionSampleRate(1.0)` in code or `profile-session-sample-rate=1.0` in `sentry.properties`
- Set a profile lifecycle via `options.setProfileLifecycle(ProfileLifecycle.TRACE)` in code or `profile-lifecycle=TRACE` in `sentry.properties`
- By default the lifecycle is set to `MANUAL`, meaning you have to explicitly call `Sentry.startProfiler()` and `Sentry.stopProfiler()`
- You may change it to `TRACE` which will create a profile for each transaction
- To automatically upload Profiles for each transaction in a Spring Boot application
- set `sentry.profile-session-sample-rate=1.0` and `sentry.profile-lifecycle=TRACE` in `application.properties`
- or set `sentry.profile-session-sample-rate: 1.0` and `sentry.profile-lifecycle: TRACE` in `application.yml`
- Profiling can also be combined with our OpenTelemetry integration
