### Fixes

- Update `sample_rate` of _Dynamic Sampling Context (DSC)_ when making sampling decisions ([#4374](https://github.com/getsentry/sentry-dotnet/pull/4374))
- Crontabs now support day names (MON-FRI) and allow step values and ranges to be combined ([#4407](https://github.com/getsentry/sentry-dotnet/pull/4407))

## 5.13.0
