ADDED UE-14356 HLOD: Print user friendly message if you try build and meshes don't have have LODs
ADDED MergeStaticMeshComponets to MeshUtilities needed for next CHANGE
ADDED HLOD preview build step for maps, this only builds the clusters for previewing the settings
ADDED SphereComponent now takes into account min and max drawing distances
ADDED Global forward declares and removed local ones from HierarchicalLOD.h
ADDED Visualization to LODActor class, uses USphereComponent to render its bounds
ADDED IsPreviewActor flag to LODActor class, if true during cluster generation DrawSphereComponents bounds will be used instead of LODActor's
ADDED vertex duplication removal on import
ADDED vertex/index buffer cache optimization on import
CHANGED World.h now forward declares HierarchicalLODBuilder to minimize (re)compile time
CHANGED While building/merging actors HLOD system now takes the orginal staticmesh from previously merged LODActors, this to enable retrieving the correct LOD per mesh (related to UE-15398)
CHANGED HLOD Cluster generation process, now takes into account HierarchicalLODVolumes to exclude actors from cluster generation
CHANGED Renamed CalculateRawMeshTangents to ExtractMeshDataForGeometryCache
FIXED Crash where a nullptr actor was added to actors list for > LOD0 clusters
FIXED Bound creation for actor within a cluster used FVector.Size(), now used FVector.AbsMax()
MOVED FLODCLuster structure into seperate header and cpp file

UETOOL-332 - Collections 2.0
UETOOL-401 - Add support for dynamic collections
You can now reference both static and dynamic collections in the Content Browser text filter, including recursive references (the evaluator guards against cyclic collection references).
The text filter now recursively gathers up any dynamic collection references when the filter text is changed. These are then tested depth first as sub-expressions against each object, to see whether the object is "contained" within the given dynamic collection.

UETOOL-332 - Collections 2.0
UETOOL-401 - Add support for dynamic collections
These collections can be created from a text search in the Content Browser, and allow you to store a search query so it can be reused or shared.
They have some limitations compared to static collections:
- As they never know what objects they actually contain, they can't be displayed in the "Collections" list in asset tooltips.
- They cannot contain child collections.

UE-17782 - Editor must be restarted for New Collections to appear after syncing
These use FFileCache to avoid detecting changes that are made by the collection manager itself.
This also fixes some issues when merging collection sets together, and fixes some places where UI wouldn't update when a collection was changed due to an update or merge.
