v0.7.3

Highlights

Faster linting for large codebases

Rslint 0.7.3 reduces repeated work across the linting pipeline with parallel TypeScript Program construction, shared program metadata and configuration plans, and optimized rule hot paths. This release also expands adoption of the shared Refs API, improving the consistency of reference resolution across rules.

12 new rules

This release adds 12 rules across ESLint, Jest, Unicorn, and Rstest, expanding coverage for control flow, error handling, modern Node.js patterns, collection usage, and test quality.
