 # Changelog
 
-[0.5.1]
-
-- Fixed optimizer bug where `StoreBatch` and `StoreBatchNamed` instructions
-  were not recognized as reading operands, causing incorrect elimination of
-  necessary device property loads
-- Added comprehensive register read tracking for `StoreSlot`, `JumpRelative`,
-  and `Alias` instructions in the optimizer
-
 [0.5.0]
 
 - Added full tuple support: declarations, assignments, and returns
