Here's a condensed release description for GitHub:
What's new in 1.1.0
TypeScript support
Lineup now scans .ts / .tsx projects for V8 JIT memory layout inefficiencies. V8 stores number properties as unboxed 8-byte doubles and everything else as 4-byte tagged pointers — interleaving them wastes memory the same way Go struct padding does. Lineup analyzes class, interface, and object type alias declarations and suggests an optimal property order.
Language selector
Pick Go or TypeScript before each scan. The architecture selector is hidden for TypeScript scans (V8 always uses 64-bit pointer compression). A default language preference is available in Settings.
Declaration kind badges
Results cards and the detail panel now show a class, interface, or type badge for TypeScript results. The toolbar label adapts to "declarations" for TypeScript scans.
