+## [1.0.0-preview.6]
+
+- Added `Jump(TimeSpan)` and `Jump(DateTimeOffset)` methods that will jump time to the specified place. Any timer callbacks between the start and end of the jump will be invoked the expected number of times, but the date/time returned from `GetUtcNow()` and `GetTimestamp()` will always be the jump time. This differs from how `Advance` and `SetUtcNow` works. See the readme for a detailed description.
+
 ## [1.0.0-preview.5]
 
 Aligned the public API surface of `ManualTimeProvider` with `Microsoft.Extensions.Time.Testing.FakeTimeProvider`. This means:
