# 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
