Panic allows only one thread to become the panic thread. In panic mode, logs are only sent to panic-safe output devices. Each call to Panic flushes buffered logs to panic-safe output devices, and flushes panic-safe output devices.

Setters and getters are native functions called by FProperties when setting property values with *_InContainer functions.
Setters and getter function names can be manually specified with Setter = Func and Getter = Func keywords inside of UPROEPRTY macro but they will also be automatically parsed if the name is not explicitly specified if the setter or getter function name matches SetPropertyName and GetPropertyName pattern.
The latter behavior can be disabled in UHT's DefaultEngine.ini by setting AutomaticSettersAndGetters=False.
ImportText and ExportTextItem functions have been deprecated and should be replaced with *_InContainer or *_Direct variants.

2) Added new struct and class specifiers to account for settings being extracted from the engine code.
3) UHT no longer depends on pre-existing classes in the engine but will use them when it needs to create the engine instances of the classes.

The process of cooking would ensure that every BP derived from a C++ base using sparse class data would have its own sparse class data instance, as the serialization function would create an instance on save/load. This could potentially result in a lot of redundant instances that don't override any data from their archetype.
These changes allow the API for accessing sparse class data to optionally fallback to using the archetype data when possible (controlled via the EGetSparseClassDataMethod enum), though any existing code already using GetOrCreateSparseClassData (or the UHT wrapper) will continue to always create a new instance.
BPGC serialization has been updated to only save the sparse class data when it has overridden data from its archetype, and the loading code will now avoid creating the instance when no override data has been saved. This allows new code to take advantage of EGetSparseClassDataMethod by choosing to reference the archetype data instead, and the engine has also been updated to avoid calling GetOrCreateSparseClassData where possible.
Anything that requires a mutable sparse class data instance should still use GetOrCreateSparseClassData (or the UHT wrapper that doesn't take EGetSparseClassDataMethod), as otherwise you may edit data belonging to your archetype (which is why GetSparseClassData returns const data).
