This release adds robust support for catalog-based local testing, allowing users to download external testcase bundles via the new grindx --fetch-testcases command. We've also streamlined the testing workflow with new keyboard shortcuts: Ctrl+R to run tests and Ctrl+Shift+R to reset the timer. For custom problems, please note the transition to a per-directory structure under ~/.grindx/problems/, with previous custom.json support now deprecated. Enjoy a much smoother development loop with these workflow enhancements! 🚀
