 ## Latest Updates
 `Experimental`
 
-`Version 1.2.1`
-- Global update.
+`Version 1.2.2`
 - Build version for Unreal Engine 5.6.0
-- Code refactoring and decomposition.
-- Improved code security and fixed critical errors in extreme situations (e.g., when loading and managing many embedded levels, as well as during critical subsystem shutdown).
-- Improved safety when working in PIE mode.
-- Added the ability to enable and disable resource preloading for both level-loading methods.
-- New functions added: `CreateSlateWidgetLPT` and `RemoveSlateWidgetLPT`. These are special Blueprint-supported functions that allow creating a loading screen based on <b>Slate</b> and <b>UMG</b>. The target UMG is added as a child directly into Slate, which enables the widget to remain visible even when the level is opened using OpenLevel.
-- `NEW` Added the `CheckingPIE` function, which helps determine whether the game is running in the editor (PIE) or in standalone mode.
