## [1.5.2] - 2021-01-08
### Added
- During recording, there are new ways to key animated properties:
- A new Inspector context menu has been added (`Key All Animated`) that sets a key to all currently animated properties.
- It is possible to make a multi-selection of tracks to set a keyframe to all currently animated properties. If no track is selected, all recording tracks are keyed.
- If properties are selected in the curve editor, only those properties are keyed.
- `TimelineEditor.GetWindow` and `TimelineEditor.GetOrCreateWindow` to get the current Timeline window or create a Timeline window.
- `TimelineEditorWindow.SetCurrentTimeline` to change which timeline asset is opened in the Timeline window.
- `TimelineEditorWindow.lock` to lock or unlock the Timeline window.
- `TrackExtensions.GetCollapsed`, `TrackExtensions.SetCollapsed`, `TrackExtensions.IsVisibleRecursive` to get and change the visibility state of a track.
- `AnimationTrackExtensions.IsRecording`, `AnimationTrackExtensions.SetRecording`, `AnimationTrackExtensions.SupportsRecording` to get or change the recording state of an Animation track.
- Added two methods in `TrackEditor` to control how an object is bound to a track: `IsBindingAssignableFrom` and `GetBindingFrom`.
- Added Japanese translation.
- The Timeline window will automatically rebuild the graph when a notifications's properties are changed.
- The Timeline window will be automatically refreshed when a marker's properties are changed.
- Added `TimelineEditor.GetInspectedTimeFromMasterTime` and `TimelineEditor.GetMasterTimeFromInspectedTime` to convert time from master to inspected timeline and vice versa when using sub-timelines.
- Added API to improve how to get/set a `TimelineClip`'s parent track:
- `TimelineClip.GetParentTrack` (replaces obsolete property getter)
- `ItemsUtils.SetParentTrack` (extension method thar replaces obsolete property setter)
- Added a new `Seconds` time display mode and renamed previous Seconds mode to Timecode.
- `TimelinePreferences.timeFormat` field,
- `UnityEditor.Timeline.TimeFormat` enum.
- Added API for the user to clip to the track area:
- API: Relevant member to `MarkerOverlayRegion`,
- API: `MarkerOverlayRegion.trackRegion`,
- API: `MarkerOverlayRegion` constructor.
- Added _Gameplay sequence_ sample.
- This sample demonstrates how Timeline can be used to create a small in-game moment, using built-in tracks.
- Added _Customization_ sample.
- This sample demonstrates how to create custom tracks, clips, markers and actions.
