 - Add `Session.State.Unhandled` for unhandled errors that do not terminate the process ([#5919](https://github.com/getsentry/sentry-java/pull/5919))
 
+### Behavioral Changes
+
+- Measure HTTP rate-limit backoff on a monotonic clock instead of the wall clock, so that a device time change no longer lifts or extends an active rate limit ([#6030](https://github.com/getsentry/sentry-java/pull/6030))
+
 ### Internal
 
 - Add internal `UptimeClock` and `ElapsedRealtimeClock` abstractions with `Deadline` and `Stopwatch` primitives ([#6028](https://github.com/getsentry/sentry-java/pull/6028))
+- Deprecate `RateLimiter(ICurrentDateProvider, SentryOptions)` in favour of `RateLimiter(ElapsedRealtimeClock, RateLimiterConfig)` ([#6030](https://github.com/getsentry/sentry-java/pull/6030))
