These beta enhancements for cart properties are now generally available! This is a huge leap forward in making nested cart data more powerful, usable, and trustworthy across Amplitude. Here's a summary of the recent changes that are now live for everyone:

• Full Platform Support: Cart Properties now fully work with Event Block, Metrics and filters, Segment creation and group-bys, Funnels (with holding constant), Data Tables (columns, rows, filters)

• Lookup Table Support for Cart Properties: Translate values like SKUs or brand codes directly within carts into human-readable formats

• Transformations for Cart Properties: Extended support for certain merge/rename transformations

• Derived Properties with Cart Analysis: Introduced Parallel Operators to Derived Properties. Note: operators that don't currently work properly with array/cart properties are IF, CONCAT, regular math operators (SUM, SUBTRACT, MULTIPLE, DIVIDE, need to use the PARALLEL_ versions).
