Double check this is the correct sdk version once it has been released. Should include up to getsentry/sentry-python#4079

Bumped to 2.24.1 as that includes some necessary fixes.


The current profiling implementation stops the profiler automatically after 30 seconds (unless you manually stop it earlier). Naturally, this limitation makes it difficult to get full coverage of your app's execution. We now offer an experimental continuous mode, where profiling data is periodically uploaded while running, with no limit on how long the profiler may run.

To get started with continuous profiling, you can start and stop the profiler directly with `sentry_sdk.profiler.start_profiler` and `sentry_sdk.profiler.stop_profiler`.

For some applications such as web servers, it may be difficult to call `sentry_sdk.profiler.start_profiler` in every process. Instead, you can use the `continuous_profiling_auto_start` option to automatically start the continuous profiler when a transaction is started.
