Change 2783106 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream2
Introduced GC UObject clusters. GC clusters provide means to create disregard for GC subsets at load time (e.g. Materials with material expressions and their textures).
- Saves about 25ms in reachability analysis (58ms -> 33ms)
- UObject classes/instances can now be marked as cluster root objects with CanBeClusterRoot() function override.
- Cluster creation is automatic. Clusters don't require any manual handling for GC to collect them when nothing is referencing them.
- Moved token stream processing to a new class FFastReferenceFinder to make it more generic and re-usable by other code
- Removed REFERENCE_INFO macro from GC code and replaced it with a local variable (saves about ~1.9ms: 33.2ms -> 31.3ms)
Change 2773094 on 2015/11/19 by Steve.Robb@Dev-Core
Multicast script delegate check for existing bindings replaced with ensure.
Multicast native delegate no longer checks for existing bindings.
Removal of old delegate code.
Some FORCEINLINEing to improve debugging experience of stepping into delegate code.
Change 2782180 on 2015/11/27 by Graeme.Thornton@GThornton_DesktopMaster
Make scoped seconds timer class available outside of stats build. Normal usage macros still remain guarded
Added SCOPE_SECONDS_COUNTER_RECURSION_SAFE which only times during the outmost instance of a recursive function
Added SCOPE_SECONDS_COUNTER_RECURSION_SAFE_BASE and SCOPE_SECONDS_COUNTER_BASE which are defined in all build types, for easy temporary timing in Test/Shipping builds.
Added a boolean parameter to the timer class which can be used to disable it without having to mess around with scoping the calling code
Change 2782635 on 2015/11/30 by Graeme.Thornton@GThornton_DesktopMaster
Added GetTimeStampPair() to the filemanager and platformfile interfaces. Requests timestamps for a pair of files where we assume that both files would always exist at the same wrapper level. Allows us to skip file system queries for localization package lookups where the native file is in a pak but the localized file doesn't exist.

Change 2773114 on 2015/11/19 by Steve.Robb@Dev-Core
FMath::IsPowerOfTwo is now templated to take any type.
Change 2773643 on 2015/11/19 by Steve.Robb@Dev-Core
GetDelegateInstance() calls replaced - delegate instances never compare equal unless you are comparing two unbound delegates (both null) or comparing a delegate with itself.

Change 2782538 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1
#UE4 Removed DiskCachedAssetDataBuffer as it was not strictly necessary and was triggering a crash when loading the cached registry from disk. This data is now stored directly in DiskCachedAssetDataMap. It was already true that this map does not change outside of SerializeCache but now it is critical since NewCachedAssetDataMap keeps pointers directly to its values.
Asset registry fixes by Bob Tellez. Possible fix for UE-23783.
Change 2782564 on 2015/11/30 by Robert.Manuszewski@Robert.Manuszewski_NCL_Stream1
FReferenceCollector::AddReferenceObjects performance improvements for TArrays. ARO will no longer call HandleObjectReference multiple times but instead will call HandleObjectReferences just once (currently only implemented for FGCCollector). Reduces the number of virtual function calls while GC'ing.
Change 2782716 on 2015/11/30 by Steve.Robb@Dev-Core
UObject serial number array initialized for debug visualization.
Change 2782933 on 2015/11/30 by Steve.Robb@Dev-Core

2. Parallelized search for old CDOs referencers.

Change 2762632 on 2015/11/11 by Steve.Robb@Dev-Core
Some TSet function optimisations:
Avoiding unnecessary hashing of function arguments if the container is empty (rather than the hash being empty, which is not necessarily equivalent).
Taking local copies of HashSize during iterations.
Change 2762936 on 2015/11/11 by Steve.Robb@Dev-Core
BulkData zero byte allocations are now handled by an RAII object which owns the memory.

[CL 2772222 by Robert Manuszewski in Main branch]
All changes regarding e-mail discussion titled "Asset registry shenanigans".
Changes:
1. Engine now actively is getting rid of short asset paths in FStringAssetReference during saving (for all packages) and loading (only for older packages).
2. Deprecated direct access to FStringAssetReference.AssetLongPathname and exposed it via ToString and SetPath -- SetPath is making sure the path is in correct format. If the path can't be found on disk, the path is cleared.
3. Also access to FStringAssetReference.AssetLongPathnam via Blueprints is guarded using custom Make node function that uses SetPath instead of simple assign.
4. StringAssetReferenceMap will now contain only paths to packages (not objects) and ini references
5. GetDependencies now has additional parameter that lets you chose if it should resolve ini references or not. It was left not as default to keep old behaviour.
[CL 2630589 by Jaroslaw Palczynski in Main branch]
References to hot-reloaded class are updated in blueprints (before recompiling and reinstancing).
I guess it could be optimized if necessary.

All children classes are recompiled before any object is reinstanced.

- CDO property values that have changed after hot-reload will now be propagated to the existing instances
- Adding code to a non-code project will no longer require restarting the editor to be able to work with new code (the new module will automatically be compiled and loaded)
