- Add `DiscardReason.CALLBACK_ERROR` and use it for telemetry dropped when a `beforeSend*` callback throws. `OnDiscardCallback` can now receive this value.
- Drop telemetry and record `callback_error` when a customer event processor throws instead of continuing with a potentially partially processed item. SDK-owned processor failures are logged and processing continues without a `callback_error` client report.
- Drop breadcrumbs when `beforeBreadcrumb` throws instead of storing exception details on the breadcrumb.
- When `tracesSampler` throws, inherit the parent sampling decision or leave the trace unsampled if there is no parent decision, instead of falling back to `tracesSampleRate`.
- When `tracesSampler` throws, inherit the parent sampling decision or leave the trace unsampled if there is no parent decision, instead of falling back to `tracesSampleRate` ([#6163](https://github.com/getsentry/sentry-java/pull/6163))
- Disable URL caching when reading `META-INF/MANIFEST.MF` files during version detection so that the SDK no longer keeps jar file handles open for the life of the process ([#6124](https://github.com/getsentry/sentry-java/pull/6124)
- Keep the `EventListener` wrapped by `SentryOkHttpEventListener` per `Call` ([#6003](https://github.com/getsentry/sentry-java/pull/6003))
