Due to the prevalence of SSDs, the Boot cache no longer offers the performance benefits that it once did, and its startup cost now often cancels out its performance gains.
Additionally, there are cases where different values are being written for the same key, which is incorrect but has not been fixed; and the Boot cache ignores the second and subsequent writes, which can cause out-of-date content to be loaded from the Boot cache in a future session.

- Frames track: Added "start time" and "fps" to the hovered frame tooltip. Also improved its appearance.
- Frames track: Improved distribution of values on vertical axis when zooming in vertically.
- Frames track: Also improved horizontal axis (ex. labels are now displayed on top; not hidden anymore when zooming in vertically).
- Frames track: Changed labels of vertical axis to move on the left or right side of view if the user hovers a frame in their area.
- Frames track: Added "Zoom Timing View on Frame Selection" toggle option in context menu of Frames track. If enabled, the Timing view will also be zoomed when a frame is selected.
- Added default ini file with following settings:
[Insights.TimingProfiler]
DefaultZoomLevel=5.0
bAutoHideEmptyTracks=True
bAutoZoomOnFrameSelection=False
AutoScrollFrameAlignment=game
AutoScrollViewportOffsetPercent=0.1
AutoScrollMinDelay=0.3
(see Engine\Programs\UnrealInsights\Config\DefaultUnrealInsightsSettings.ini for detailed description of each setting)
Above settings (except the DefaultZoomLevel) can be changed directly from UI and Unreal Insights will remember that settings.
- Timing view: Changed all settings related to "auto scroll" to be persistent in the ini file.
- Added SetScaleX(ScaleX) to FTimingTrackViewport.

Allow UnrealObjectPtrTool to perform reverse upgrades when the "-r" commandline argument is used. Also added functionality to allow UnrealHeaderTool to dump out necessary log messages specifying TObjectPtr member declrations for UnrealObjectPtrTool to consume.
Tested by:
1) Performing a new forward pointer upgrade (from a new UHT log) and confirming the resulting files had zero diffs when compared to a shelf of upgraded files from previous version of UnrealObjectPtrTool.
2) Performed a forward pointer upgrade, then a reverse pointer upgrade then reverted all unchanged files. The remaining files (13 of them see shelved CL15213431) only had trailing whitespace corrections due to the deliberate choices for trailing whitespace manipulation when doing forward upgrades.

#jira UE-88070 - UnrealDisasterRecoveryService paths are too long
- Renamed UnrealDisasterRecoveryService as UnrealRecoverySvc
- Set a ConcertSyncServer ShortName as "CncrtSyncSvr" to ensure shorter build path.
The change saves 29 characters on the offending path. The path before vs the path after:
Engine\Plugins\Developer\Concert\ConcertSync\ConcertSyncServer\Intermediate\Build\Win64\UnrealDisasterRecoveryService\Development\ConcertSyncServer\UnrealDisasterRecoveryService-ConcertSyncServer.lib (Before, 199 chars)
Engine\Plugins\Developer\Concert\ConcertSync\ConcertSyncServer\Intermediate\Build\Win64\UnrealRecoverySvc\Development\CncrtSyncSvr\UnrealRecoverySvc-ConcertSyncServer.lib (After, 170 chars)
